Safety Information
The CY8CKIT-042-BLE Bluetooth Low Energy (BLE) Pioneer Kit is intended for use as a
development platform for hardware or software in a laboratory environment. The board is an open
system design, which does not include a shielded enclosure. Due to this reason, the board may
cause interference with other electrical or electronic devices in close proximity. In a domestic
environment, this product may cause radio interference. In such cases, the user may be required to
take adequate preventive measures. Also, this board should not be used near any medical
equipment or critical RF devices.
The CY8CKIT-042-BLE Bluetooth Low Energy (BLE) Pioneer Kit is intended for use as a
development, demonstration and evaluation platform for hardware or software in a laboratory
environment. The kit is not intended for general consumer use. Cypress recommends that the kit
only be used in a shielded room.
Attaching additional wiring to this product or modifying the product operation from the factory default
may affect its performance and cause interference with other apparatus in the immediate vicinity. If
such interference is detected, suitable mitigating measures should be taken.
The CY8CKIT-042-BLE boards contain electrostatic discharge (ESD)
sensitive devices. Electrostatic charges readily accumulate on the
human body and any equipment, which can cause a discharge without
detection. Permanent damage may occur on devices subjected to
high-energy discharges. Proper ESD precautions are recommended
to avoid performance degradation or loss of functionality. Store unused
CY8CKIT-042-BLE boards in the protective shipping package.
End-of-Life/Product Recycling
The end-of-life cycle for this kit is five years from the date of
manufacture mentioned on the back of the box. Contact your nearest
recycler to discard the kit.
CY8CKIT-042-BLE BluetoothÂŽ Low Energy (BLE) Pioneer Kit Guide, Doc. # 001-93731 Rev. *A
General Safety Instructions
ESD Protection
ESD can damage boards and associated components. Cypress recommends that the user perform
procedures only at an ESD workstation. If an ESD workstation is not available, use appropriate ESD
protection by wearing an antistatic wrist strap attached to the chassis ground (any unpainted metal
surface) on the board when handling parts.
Handling Boards
CY8CKIT-042-BLE boards are sensitive to ESD. Hold the board only by its edges. After removing
the board from its box, place it on a grounded, static-free surface. Use a conductive foam pad if
available. Do not slide the board over any surface.
Battery Care and Use
â
Use the correct size and type of battery specified in this guide.
â
Keep battery contact surfaces and battery compartment contacts clean by rubbing them with a
clean pencil eraser or a rough cloth each time you replace batteries.
â
Remove the battery from a device when it is not expected to be in use for several months.
â
Make sure that you insert the battery into your device properly, with the + (plus) and â (minus)
terminals aligned correctly.
â
Do not place the battery next to metallic objects such as keys and coins.
â
Never throw the battery into fire.
â
Do not open up the battery.
â
Do not short the battery.
â
Do not subject the battery to high temperatures or high humidity.
â
Store the battery in a dry place.

The BLE Pioneer board acts as the baseboard for the PSoC 4 BLE (red module) and PRoC BLE
(black module). The Pioneer board contains a PSoC 5LP that is used as an onboard programmer or
debugger, and for the USB-Serial interface.
The baseboard is Arduino form-factor compatible, enabling Arduino shields to be connected on top
of the board to extend the functionality of BLE modules. The board also features a 1-Mb F-RAM, an
RGB LED, a five-segment CapSense slider, a proximity header, a user switch, and a reset switch for
the PSoC 4 BLE and PRoC BLE devices on the module. The Pioneer board supports three voltage
levels: 1.9 V, 3.3 V, and 5 V.
The baseboard can also be used as a standalone programmer to program and debug other PSoC 4
BLE/PRoC BLE devices using serial wire debug (SWD), and as a USB-Serial bridge. The firmware
on PSoC 5LP device enables bootloading PSoC 5LP over USB to upgrade the firmware.

This kit includes two modules boards. These boards act as a basic breakout board for the
CY8C4247LQI-BL483 and CYBL10563-56LQXI BLE silicon. The PSoC 4 BLE and PRoC BLE
Modules are identical except for the silicon. In addition to including the PSoC 4 BLE and PRoC BLE
devices, the module boards also contain the BLE passives (resistors, capacitors, external crystals,
and antenna-matching network), an onboard antenna, and headers for connecting to the baseboard.
The BLE dongle is the host's wireless interface for the BLE device or project on the baseboard. The
dongle has a PRoC BLE device, to allow BLE connection with other kits. It also contains a
PSoC 5LP, to be used as an onboard programmer or debugger, and for the USB-Serial interface, as
shown in Figure 3-3.
The dongle has a USB A-type plug to connect the PSoC 5LP to the USB port of the host PC. The
PSoC 5LP then communicates with the PRoC BLE device over UART or multiplexed I2C or an SPI
bus. The board also features a user LED, a user switch, and a reset switch for the PRoC BLE
device. The dongle is powered directly through the USB port (VBUS) at 5.0 V.
The BLE dongle can also be used as a standalone programmer to program and debug other PSoC
devices (outside the dongle board) using SWD, and as a USB-Serial bridge after removing the
resistor between the SWD pins of PSoC 5LP and PRoC BLE.

USB-UART Bridge
The onboard PSoC 5LP on both the baseboard and dongle acts as a USB-UART bridge to transfer
and receive data from the PSoC 4 BLE or PRoC BLE device to the PC via the COM terminal
software. When the USB mini-B cable is connected to J13 of the baseboard or the dongle is
connected to the PC, a device named âKitProg USB-UARTâ is available under Ports (COM & LPT)
in the Device Manager. To use this functionality, a project supporting UART communication must be
created on the BLE device. More details are available in the section Using PSoC 5LP as USB-UART
Bridge on page 115.
For both the baseboard and the dongle, the UART lines are hardwired onboard between the PSoC
5LP and BLE Modules. No external UART connection between the two devices is needed. Simply

The PSoC 5LP also functions as a USB-I2C bridge. In this role, PSoC 5LP communicates with
PSoC 4 BLE/PRoC BLE using an I2C interface, and sends that data over the USB to the USB-I2C
software utility running on the PC, called the Bridge Control Panel (BCP). This feature is available
for both the BLE Pioneer Kit and the BLE dongle.
The BCP is available as part of the PSoC Programmer installation. This software can be used to
send and receive USB-I2C data from the PSoC 5LP. When the USB mini-B cable is connected to
header J13 on the BLE Pioneer Kit or when the dongle is connected to the PC, the KitProg USB-I2C
is available under Connected I2C/SPI/RX8 Ports in the BCP, as shown in Figure 3-23.
To open BCP in your system, go to Start > All Programs > Cypress > Bridge Control Panel.

Measure Coin Cell Power Consumption
To measure the power consumption of a project with coin cell, connect the coin cell directly to the
BLE modules, as shown in Figure 3-27. The baseboard is designed with additional circuits to protect
the PSoC 4 BLE/PRoC BLE device and the F-RAM in Arduino environment. Note that power
consumption measurements on the baseboard will also include the power consumed by these
additional circuits.
After you have programmed your application on the CY8CKIT-142 PSoC 4 BLE Module or the
CY5671 PRoC BLE Module, remove the BLE module from the baseboard and connect the coin cell
(Figure 3-27). This setup enables an accurate power consumption measurement for the application.

Example Projects
This chapter demonstrates the functionality of the PSoC 4 BLE and PRoC BLE devices using the
BLE Pioneer kit-based example projects. To access these example projects, download and install
the kit setup file from the kit web page. The example projects are available in the firmware folder
under the installed directory.
The Cypress BLE device comes in two variants:
4.1
â
PSoC 4 BLE: The PSoC 4 BLE product family is the new wireless member of the PSoC 4
architecture platform. The family provides a full programmable analog and digital system and a
complete schematic view of PSoC Creator. The PSoC 4 BLE family provides a 32-bit ARM
Cortex-M0 based MCU subsystem with programmable analog and digital peripherals, such as
universal digital blocks (UDBs), 12-bit SAR ADC, opamp, LP comparator, IDACs, UART, I2C, SPI,
and timer/counter/PWM block. It also has a dedicated CapSense block (in select part numbers)
to implement the touch-sensing solution, with a practical system SNR of 100:1.
â
PRoC BLE: This family provides prebuilt part numbers for applications such as human interface
devices (HID), remote control, trackpad, and toys. PRoC BLE also supports up to two-finger
gestures for trackpad and remote control applications. The PRoC BLE product family enriches
the PRoC wireless capacitive touch devices with the Bluetooth Low Energy protocol. The PRoC
BLE family has embedded gestures (in select part numbers) to implement the touch-sensing
solution for trackpad implementation. It also provides a 32-bit ARM Cortex-M0 based MCU
subsystem with analog and digital peripherals, such as 12-bit SAR ADC, UART, I2C, PWMs, and
timer/counter/PWM blocks. The family uses a special PSoC Creator schematic view for easy
configuration of PRoC BLE devices.

Example Projects
Figure 4-1. Open Example Project from PSoC Creator
4. Select the folder where you want to save the project and click OK.
5. BLE projects use a public device address set in the BLE component GUI to advertise and scan,
depending on the role: peripheral or central mode. If there are other kits in close proximity, which
have the same public device address, then wrong devices may be connected or connections can
fail. To prevent this, you can change the Public device address (and preferably Device name)
in the BLE component. To do this, double-click the BLE component in TopDesign, go to the GAP
Settings tab, and choose the General setting. Add the desired public device address (non-zero)
and device name in the respective fields, as shown in Figure 4-2. Click OK.
Alternatively, you can select the 'Silicon generated' device address by selecting the check box.
This way, the BD address is generated using the silicon ID, unique to each silicon. Click OK.

Figure 4-6. Connect Device From PSoC Creator and Program
Note: As stated previously, the BLE Pioneer kit supports both Cypress BLE devices: PSoC 4 BLE
and PRoC BLE. Thus, there are two versions of each of the kit example projects demonstrating the
same functionality. Projects named with the prefix PSoC_4_BLE_ work with the PSoC 4 BLE Module
placed on the baseboard. Projects named with the prefix PRoC_BLE_ work with the PRoC BLE
Module placed on the baseboard. Ensure that the correct module is placed on the baseboard before
programming the device with the corresponding kit example projects.
The description, hardware configurations, and verification method of the kit example projects
explained in the following sections are valid for both PSoC 4 BLE and PRoC BLE devices. Unless
explicitly mentioned, the theory and usability for these example projects should be considered the
same for both the modules/devices.
This document refers to the BLE Pioneer kits, dongle, and PC/mobile as BLE Central or peripheral
devices. A BLE Central device is normally the master and requests/commands data from the
peripheral device. BLE-enabled phones and PCs are one such example. BLE peripheral devices, on
the other hand, store the actual data and send it to central devices when requested. Examples
include BLE-enabled sensors, proximity beacons, and so on.

CapSense Slider and LED
4.2.1
Project Description
This project demonstrates BLE connectivity between the BLE Pioneer kit (acting as a peripheral and
server device) and BLE dongle or mobile device running the CySmart application (acting as a central
and client device). This project demonstrates following:
â
Advertisement with timeout
â
Connection with any BLE Central device
â
Two custom services in single profile
â
Data transfer over BLE custom service using notifications, read, and write
â
Low-power mode implementation for battery operation
The BLE profile in this project consists of two BLE custom services: CapSense and RGB LED. The
CapSense service consists of one custom characteristic, termed as CapSense Slider. The
CapSense slider characteristic is used to send one byte data, ranging from 0 to 100, as notification
to the client device. This data is the finger location read by the CapSense component on the fivesegment slider (CSS1) present on the kit. This characteristics supports notification, which allows the
BLE server to send data to the connected client device whenever new data is available.
The RGB LED service also consists of one custom characteristic, termed as RGB LED Control.
This characteristic supports two operations, read and write, through which the connected client
device can read data as well as write a new value to the characteristic. This data has four byte values indicating red, green, blue, and intensity values for the onboard RGB LED.
These properties for the custom service/characteristics are configured in the BLE component under
the Profiles tab, as shown in Figure 4-7.

Example Projects
The project consists of the following files:
â
main.c/.h
These files contain the main function, which is the entry point and execution of the firmware application. It also contains function definition for initialization of the system and reading the
CapSense slider data from the CapSense component.
â
BLEApplications.c/.h
These files contain all the macros and function definitions related to BLE communication and
operation. It contains the event callback function definition that is registered with the BLE component startup and used by the component to send BLE-related events from the BLE stack to the
application layer for processing. It contains a method to send CapSense notifications to the client
device and process the Read and Write commands on the RGB LED characteristic by the client
device. It updates the BLE Connection parameter, which is important for low-power mode usage.
â
HandleLowPower.c/.h
These files contain the function to handle low-power mode. This function is continuously called in
the main loop and is responsible for pushing the BLE hardware block (BLESS) as well as the
CPU to Deep Sleep mode as much as possible. The wakeup source is either the BLE hardware
block Link Layer internal timer or the interrupt from the user button press (SW2). This allows for
very low power mode implementation and operation using a coin cell.
Additionally, the PRoC BLE version of this project consists of the RGB_PRSm.c/.h file, which contains the function to drive the software-based PrISM method and drive the color and intensity on the
RGB LED.
This is the default firmware that comes in the BLE modules shipped with the kit.
Two projects demonstrate this functionality on two different devices:
â
PSoC_4_BLE_CapSense_Slider_LED works with the PSoC 4 BLE Module
â
PRoC_BLE_CapSense_Slider_LED works with the PRoC BLE Module.
The PSoC 4 BLE project implements RGB color and intensity control using the PRiSM component
whereas the PRoC BLE uses the software implementation of the PRiSM mode.

CapSense Proximity
4.3.1
Project Description
This project demonstrates BLE connectivity between the BLE Pioneer kit (acting as a peripheral and
server device) and the BLE dongle or mobile device running the CySmart application (acting as a
central and client device). This project demonstrates the following:
â
Advertisement with timeout
â
Connection with any BLE Central device
â
One custom service
â
Data transfer over BLE custom service using notifications
â
Low-power mode implementation for coin cell operation
The BLE profile in this project consists of a single BLE custom service, called CapSense. The
CapSense service consists of a custom characteristic, termed as CapSense Proximity. The
CapSense proximity characteristic is used to send one byte data, ranging from 0 to 255, as
notification to the client device. This data is the difference count read by the CapSense component
on the one-wire proximity sensor (J14) connected on the kit. This characteristics supports
notification, which allows the BLE server to send data to the connected client device whenever new
data is available.
The properties for the custom service/characteristics are configured in the BLE component under the
Profiles tab, as shown in Figure 4-32.

BLE Central Mode
4.4.1
Project Description
The BLE projects described above have been functioning as BLE peripheral devices. This means
that the firmware role was set to be a BLE peripheral and server; another device such as the
CySmart PC tool or CySmart mobile application will connect to it and collect the data.
This example project demonstrates the BLE central and client mode where it will scan for a peripheral device, connect to it, and send commands. In this project, the BLE Pioneer kit scans and autoconnects to a particular peripheral device supporting Immediate Alert Service (IAS). Whenever the
peripheral with a predetermined address is found, a connection request is sent followed by discovering the attributes. When the discovery is over, you can send one of the three alert levels to the BLE
peripheral device over the IAS. This is done by pressing the SW2 button on the BLE Pioneer kit and
cycling through the alert levels.
The BLE central project supports low-power mode operation, where the firmware supports BLESS
and CPU Deep Sleep mode whenever possible. The system remains in deep sleep when disconnected. Press SW2 to wake up the system and start scanning (blinking blue LED). The scanning
timeout interval is set to 30 seconds. If the particular BLE peripheral device is found advertising
before timeout, a connection is made (blue LED always ON). If no such device is found, then the
CY8CKIT-042-BLE BluetoothÂŽ Low Energy (BLE) Pioneer Kit Guide, Doc. # 001-93731 Rev. *A

Example Projects
system stops scanning and returns to Deep Sleep mode (LED OFF). Press SW2 again to wake the
system and restart scanning.
To aid in evaluation, the BLE peripheral project with the particular BD address is provided in the
same workspace. This peripheral project supports IAS and has fixed BD address that the central
device will recognize and auto-connect to. This peripheral project is programmed on the BLE dongle
and powered through the USB port of PC. The received alert levels (No, Mid, and High alert) on the
BLE dongle are represented by different LED status. No Alert is represented by LED OFF, Mid Alert
by blinking LED, and High Alert with LED always ON. Upon each successive button press on the
BLE Pioneer kit, the LED state on the BLE dongle changes in a circular fashion.
Two projects demonstrate the BLE Central functionality on the two devices:
â
PSoC_4_BLE_Central_IAS works with the PSoC 4 BLE Module.
â
PRoC_BLE_Central_IAS works with the PRoC BLE Module.
Additionally, the BLE_Dongle_Peripheral_IAS project is to be programmed on the dongle. This
project is present in both the PSoC_4_BLE_Central_IAS and the PRoC_BLE_Central_IAS workspace and can be used to program the dongle separately.
Note: If the dongle is programmed with the BLE_Dongle_Peripheral_IAS example, it will not work
with the CySmart PC utility. Reprogram the dongle with the CySmart firmware according to Updating
BLE Dongle for CySmart PC Tool on page 33 to use the CySmart PC tool.

BLE Dongle and LED Control
4.5.1
Project Description
This firmware supports the CySmart debug tool (see CySmart PC Tool on page 160) by acting as the
BLE host emulator. This is the default firmware that comes in the BLE dongle shipped with the kit.
This project additionally demonstrates LED brightness control via a custom BLE profile, which works
with the CapSense slider example explained in CapSense Slider and LED on page 47.
The device will scan for the peripheral acting as a CapSense slider and LED device, and connect to
it automatically. This is achieved by filtering the advertisement packets for the CapSense Slider
service data, which will be sent by the CapSense slider example. Then, it will enable slider
notifications and process the received notifications. Whenever CapSense detects activity, it will
notify the finger location to the dongle; the dongle will update the LED brightness using PWM.
The custom client LED control will be stopped if the CySmart PC tool acquires the dongle. The
dongle will enter the CySmart emulator mode, in which it will process all BLE commands as
triggered by the user via the tool. The project uses custom command/event protocol to exchange
data between the CySmart PC tool and the BLE component via a USB-CDC interface. It uses the
Cypress USB-UART bridge functionality from the PSoC 5LP-based KitProg module described in
Using PSoC 5LP as USB-UART Bridge on page 115.
Note: This project is meant only for the PRoC BLE device and works on the dongle hardware.

Direct Test Mode (DTM)
4.6.1
Project Description
Bluetooth Core specification (v4.0 and later), Volume 6, Part F defines Direct Test Mode (DTM) as a
method to test the BLE PHY layer and provide a report back to the tester. It uses one of the two
methods, over Host Controller Interface (HCI) or through a two-wire UART interface.
Device under test (DUT) is the BLE system that is to be tested (for example, BLE Pioneer kit). With
DTM, the RF performance of the BLE system can be verified during development or in production
line. The environment consists of the DUT and a tester. The tester has two parts; the upper tester
sends commands through one of the two methods (HCI or two-wire UART) and the lower tester performs the corresponding action over the RF link. The tester compares the command sent over HCI
and the response received over RF, and provides a result of the performance.
Figure 4-67. Direct Test Mode (DTM) Setup
HCI/UART
Upper
Tester
DUT
RF (2.4 GHz)
Lower
Tester
The BLE component allows configuring the device in DTM by enabling the HCI. The appropriate
response to commands from the tester are performed by the BLE stack and does not involve separate application handling. The only task is to start the BLE component and call the API to process the
events.
CY8CKIT-042-BLE BluetoothÂŽ Low Energy (BLE) Pioneer Kit Guide, Doc. # 001-93731 Rev. *A
84
Example Projects
The HCI is enabled in the BLE component under the General Settings. Note that when the HCI
mode is selected, all other tabs are hidden and cannot be configured. This is because in HCI mode,
there are no upper layer processes. On enabling HCI mode in the components, the components
automatically reserves a UART block to allow communication between the tester and BLE stack.
The UART exposes the pins that can be assigned in Design Wide Resource > Pins. The only
option to be configured for HCI mode is the baud rate and the pins for communication with the tester.
Figure 4-68. HCI Mode in BLE Component
Many companies develop BLE testers for Direct Test Mode. It is also possible to create PC-based
software tools that will send HCI commands over serial communication links.
For PC-based software, the serial communication link is the COM port, which is enumerated by KitProg on PSoC 5LP of the BLE Pioneer kit. In such a case, the UART pins in PSoC 4 BLE/PRoC BLE
should be assigned to P1_4 and P1_5. These pins are hardwired to pins on PSoC 5LP and allows
USB-UART data communication between the PC tool and the BLE device.
For separate BLE testers, the serial communication is mostly over the RS232. To test with this
system, an external RS232 voltage translator is required, such as Digilent's Pmod RS232. This
translator will modify the signal level of the serial communication between the BLE device and the
RS232 port on the tester. The UART pins of the BLE device can be assigned to P0_0 and P0_1 and
the header J5 can be used to connect to the RS232 translator.

85
Example Projects
Figure 4-69. J5 Header to Interface RS232 Translator
4.6.2
Hardware Connection
For DTM test mode, it is recommended to use SMA connectors and connect the tester and DUT
using a SMA to SMA connector cable. This ensures that there is minimum interference to RF
communication between the DUT and tester, and the performance measured is the true RF
performance of the device. The BLE Pioneer kit module with SMA connector (CY8CKIT-141 PSoC 4
BLE) is available separately and can be ordered from the Cypress web page.
Four UART pins are exposed when HCI mode is selected in the BLE component. These pins should
be assigned to allow communication with the external tester. The connection depends on the tester
being used.
If the tester is a PC-based software and communicated with HCI over serial link, then the onboard
PSoC 5LP on the BLE Pioneer kit can act as the USB-UART bridge. The KitProg on the PSoC 5LP
enumerates as a USB-UART interface and opens a COM port in the PC. This COM port is then used
by the software tool to communicate commands to the BLE device. In this case, the UART pins
should be assigned as follows.

The UART for HCI communication exposes hardware flow control lines CTS and RTS. They can

If the tester is an external hardware tester (CBT), then connect any of the RS232 voltage translators
to header J5 on the BLE Pioneer kit. The UART pins should be assigned as follows.

The input to the LDO can come from either the USB, the VIN pin in the Arduino header J1 or header
J9.
Note: The typical dropout voltage of the selected LDO is 0.3 V at 500-mA output current. This gives
a minimum output of 4.6 V from the input voltage of 5 V from the VBUS. This drop also takes into
account the voltage drop across the Schottky diode connected at the output of the LDO to protect
against voltage applied at the output terminal of the regulator.

A MOSFET-based protection circuit is provided for overvoltage and reverse-voltage protection for
the 3.3-V rail from J1.5, as shown in Figure 5-4. When a voltage greater than 3.6 V is applied
from J1.5, the Q2 PMOS will turn off, which will cut off the power to the BLE module from J1.5.
When reverse voltage is applied from J1.5, the Q1 PMOS will turn off, protecting the onboard
components from reverse voltage.

The J1 header contains I/O pins for reset, I/O reference voltage (IOREF), and power supply line. The
J2 header is an analog port that contains I/O pins for SAR ADC, comparator, and opamp. The J3
header is primarily a digital port that contains I/O pins for PWM, I2C, SPI, and analog reference. The
J4 header is also a digital port that contains I/O pins for UART and PWM. The J12 header is an
Arduino ICSP compatible header for the SPI interface and is not populated. Refer to the âNo Load
Componentsâ section of Bill of Materials (BOM) on page 184 for the header part number.
Additional Functionality of Header J2
The J2 header is a 6Ă2 header that supports Arduino shields. The Port 2 and Port 3 pins of PSoC 4
BLE and PRoC BLE are brought to this header. The Port 2 pins also connect to the onboard
CapSense slider through 560-ohm resistors. When the CapSense feature is not used, remove these
resistors to help ensure better performance with these pins.

CapSense Slider
The kit has a five-segment linear capacitive touch slider, which is connected to the BLE module pins
(see Figure 5-12). The CMOD and CTANK capacitors are required for CapSense functionality and
are provided on the BLE modules (see BLE Module Board on page 106). A 2.2-nF capacitor is
present on the CMOD pin, P4[0], for CapSense operation. This kit also supports CapSense designs
that enable waterproofing. On this kit, the connection of the shield to the pin or to ground is made by
resistors R12 and R13, respectively. By default, R13 is mounted on the board, which connects the
shield to ground. Populate R12 and remove R13 when evaluating waterproofing designs, which will
connect the shield to the designated pin, P1[6].

Cypress Ferroelectric RAM (F-RAM)
The baseboard contains an F-RAM device (FM24V10) (see Figure 5-17) that can be accessed
through I2C lines P5[0] and P5[1] of the PSoC 4 BLE/PRoC BLE device. The F-RAM is 1-Mbit
(128 KB) with an I2C speed up to 1 Mbps. The I2C slave address of the F-RAM device is seven bits
wide, and the LSB two bits are configurable through physical pins and are hardwired to 00 on the
board. By default, the address of the F-RAM device used on the board is 0x50. This address can be
modified by changing the R32/R36 and R33/R37 pairs. The operating voltage range of the F-RAM is
between 2 V and 3.6 V. To prevent the application of 5 V from the adjustable LDO regulator on the
board, a MOSFET based protection circuit similar to the one used for the 3.3-V rail is connected
between the output of the regulator and the VDD pin of the F-RAM. The protection circuit cuts off the
power to the F-RAM when the output of the regulator is greater than 3.6 V.

Serial Interconnection Between PSoC 5LP and BLE Module
The PSoC 5LP onboard programmer is also a USB-Serial interface, It supports USB-UART and
USB-I2C bridges (see Figure 5-18). The pull-ups resistors on I2C bus are enabled when the protocol
is selected from user interface (like bridge control panel). The USB-Serial pins of the PSoC 5LP are
also available on the Arduino header; therefore, the PSoC 5LP can be used to control Arduino
shields with the SPI/I2C/UART interface. Refer Using PSoC 5LP as USB-UART Bridge on page 115
and Using PSoC 5LP as USB-I2C Bridge on page 126 for more information on how to use these
