Chapter 5, “1323x Remote Extender Motherboard” for detailed information. A small 8-switch
matrix, IR receiver, and USB interface provides means for communication to the MC1323x for:
— Simple keypad-only applications
— Connection to a PC
— Host connection such as for a remote control extender or remote control receiver
Whether the 1323x-MRB is used in a simple standalone application or in combination with another host
card, Freescale provides a complete software development environment called the Freescale BeeKit
Wireless Connectivity Toolkit (BeeKit). BeeKit is a comprehensive codebase of wireless networking
libraries, application templates, and sample applications. The BeeKit Graphical User Interface (GUI)
allows users to create, modify, and update various wireless networking implementations. A wide range of
software functionality is available to complement the 1323x-MRB and these are provided as codebases
within BeeKit.
2.2 Features
The MC1323x development platform is built around the concept of having a single daughter card
(1323x-MRB) that contains the MC1323x IC and all necessary I/O connections for use as a self-contained
module or for connection to an application motherboard. Figure 2-1 shows a simplified block diagram of
the more powerful Freescale configuration of the 1323x-MRB combined with the 1323x-RCM.

2.3 Driver Considerations
When users first connect a 1323x-RCM or 1323x-REM based platform to a PC, they may be prompted to
install drivers. If BeeKit is installed and this occurs, do not allow Windows to automatically search for and
install the drivers. Instead, select manual installation and steer Windows to the following directory:
C:\Program Files\Freescale\Drivers
If installing the BeeKit software package to another drive or directory, indicate the Drivers directory
created by the installer in the custom location where BeeKit was installed.
Follow the instructions as they appear on the screen to complete driver installation.
If BeeKit is not installed, be aware of the following:
• The boards use the FTDI serial to USB converter, Virtual COM Port (VCP) driver for Windows,
available at www.ftdichip.com/ftdrivers.htm.
(Direct (D2XX) drivers are also available.)
• The FTDI web site offers drivers for other platforms including Windows® (98 through Vista x64
and CE), MAC OS (8 through X) and Linux.
• Download the appropriate driver and follow the instructions to complete driver installation.

Figure 3-2 shows a footprint of the 1323x-MRB with the location of the IO Headers J2 and J3. The user
may desire to create a motherboard on which the 1323x-MRB would be mounted, and headers J2 and J3
are used for connection to the motherboard:
• Both headers have standard 0.10in / 2.54 mm pin spacing
• J2 is 20-pin and J3 is 18-pin
• Both are pin headers mounted on the bottom side of the 1323x-MRB and are intended to plug into
matching receptacles on the motherboard.
• It is recommended that 1323x-MRB be located such that it extends beyond edge of the
motherboard (see Figure 3-2) so that the entire F-Antenna is exposed with no motherboard ground
or voltage plane beneath it. This is to allow best results transmitting and receiving with the radio.
• With the 1323x-MRB oriented as shown in Figure 3-2, the IR blaster transmits to the right.

3.2.1 RF Performance and Considerations
The MC1323x transceiver includes a low noise amplifier, 1mW nominal output power, PA with internal
voltage controlled oscillator (VCO), integrated transmit/receive switch, on-board power supply regulation,
and full spread-spectrum encoding and decoding.
• Nominal output power is 0 dBm, with +3 dBm max
• Typical sensitivity is -93 dBm
• Frequency range is 2405 to 2480 MHz
• Typical range (outdoors, line of sight) is 130 meters
The 1323x Modular Reference Board utilizes a minimum number of components while providing good
RF performance:
• Uses a minimum number of RF matching components and external 50:100 balun
• “F” printed metal antenna for a small footprint, low cost design
An external 50 (unbal):100 (bal) balun connects a single-ended 50-Ω port to the differential RF port of the
MC1323x radio. The layout has provision for out-of-band signal suppression (components L2 and C7) if
required. Also note that control pin CT_Bias switches reference voltage to the balun as required for TX
(CT_Bias = 1.5V) or RX (CT_Bias = ground).
The default RF mode is use of the “F” antenna coupled through 10 pF C3 to the single-end RF port. An
alternative mode is to connect an SMA RF connector (not provided; must be mounted). This is useful for
connected measurements to test radio performance.

Figure 3-4. 1323x-MRB RF Circuitry
3.2.2 Clocks
The MC1323x provides for two clocks:
• 32 MHz Reference Oscillator - Figure 3-5 shows the external 32 MHz external crystal Y2. This
mounted crystal must meet the MC1323x specifications. The IEEE 802.15.4 Standard requires that
the frequency be accurate to less that +/-40 ppm.
— Capacitors C10 and C11 provide the bulk of the crystal load capacitance. Onboard trim
capacitors can be programmed to center the frequency. At 25°C, it is desired to have the
frequency accurate to +/-10 ppm or less to allow for temperature variation.
— To measure the 32 MHz oscillator frequency, signal PTD7/XTAL_32MOUT can optionally be
programmed to provide a buffered output clock signal
— The 1323x-MRB has provision for injecting an external 32 MHz clock source as an alternative
to use of the onboard crystal:
– The crystal Y2 should be removed
– Resistors R23, R24, R19, and R20 must be mounted
– C23 must be mounted
– The external 32 MHz source is connected to 2-pin header J8; the frequency accuracy of the
external source must meet the +/-40 ppm of the IEEE 802.15.4
• Optional 32.768 kHz Crystal Oscillator - Provision is also made for a secondary 32.768 kHz crystal
X2 (see Figure 3-6). This oscillator can be used for a low power accurate time base.
— The module comes provided with this Y1 crystal and its load capacitors C4 and C15.
— Load capacitors C4 and C15 provide the entire crystal load capacitance; there is no onboard
trim capacitance.
— The 32 kHz oscillator components are supplied, but un-enabled. Zero-ohm resistors R11 and
R13 enable use of IO signals PTA0 and PTA1 via the IO connector and are supplied as mounted.
These must be unmounted and moved to resistor sites R10 and R12 to enable the 32.768 kHz
crystal and disable PTAO and PTA1.

• The Freescale 1323x-RCM and 1323x-REM development boards
generate the system power supply on the motherboard and supply the
voltage to the 1323x-MRB through the V_BRD pin of Headers J2 and
J3. In this mode, the current flows to the 1323x-MRB through the pins.
• If an external supply is used via 1323x-MRB header J5, current flows to
the motherboard through the V_BRD pin of Headers J2 and J3. THE
MOTHERBOARD SUPPLY SHOULD NOT BE USED.
• In all modes, the IO voltage supply of peripherals on a motherboard
must be the same voltage as V_BRD, which is also the voltage applied
to the IC MC1323x.

3.3.2 IO Connectors J2 and J3
The two IO connectors J2 and J3 are standard 100 mil pin headers mounted on the back (non-component
side) of the 1323x-MRB. The primary header J2 is 20-pin and the secondary header J3 is 18-pin, and they
are mounted physically in such a manner as to prevent reverse insertion of the 1323x-MRB into a
motherboard receptacle (see Figure 3-2). When the 1323x-RCM or 1323x-REM or custom motherboard
is plugged into these connectors, they allow access to MC1323x MCU GPIO.
• V_BRD is the connector supply voltage.
— Depending on power supply configuration, this voltage may supply the 1323x-MRB from the
motherboard or the 1323x-MRB may supply this voltage to the motherboard. See
Section 3.3.1, “Power Management”.
— Peripherals IO to the MC1323x and the MC1323x supply should use this same voltage
NOTE
The 1323x-RCM and 1323x-REM and 1323x-MRB are supplied configured
for the motherboard to supply main power.
• Some of the GPIO are shared with onboard devices. Check for the 1323x-MRB schematic and
Table 3-4 and Table 3-5 for any conflict.
• BDM port signal PTA7/BKGD is NOT connected to the IO headers to prevent possible interference
with the debug port.

3.3.3 1323x-MRB Onboard Peripheral Functions
The 1323x-MRB has two onboard peripheral functions to assist in implementing targeted applications.
NOTE
To use the peripherals, a minimum power supply voltage of 2.7 V must be
maintained.
3.3.3.1 2 Mbit Serial FLASH (SPI Interface)
Component U2 is an Atmel AT45DB021D 2 Mbit (256 kbyte) serial FLASH memory with SPI interface.
The memory is useful for over-the-air programming (OTAP) and for storage of non-volatile system data
or parameters. Figure 3-9 shows the memory circuit.
• Memory power supply is V_MEM (Header J9, Pin 1-2)
• Disabling the memory supply V_MEM may load the MC1323x SPI port through the U2 ESD
diodes
• Discrete pullup resistors for the SPI port are provided
• The SPI can be shared with another peripheral - an additional IO signal would be required as a chip
enable (CS or SS) for the peripheral. The normal SPI_SS and the second chip select should NOT
be active at the same time.

3.3.3.2 IR Transmitter (Blaster)
An IR transmitter or blaster is provided to control IR legacy components (see Figure 3-10).
• The IR power supply is V_LED (Header J9, Pin 7-8)
• The IR transmitter has approximately a 10 meter range.
• Current draw is approximately 80 mA when active.
• To reduce the peak current consumption, it is recommended that the IR transmitter only be active
when the MC1323x RF transceiver is in-active.
• When using the blaster in an application, observe proper orientation (see Figure 3-2)

4.2 Functional Description
The 1323x-RCM is a host motherboard for the 1323x-MRB. The two-board combination provides a
powerful evaluation and development platform for the MC13233. Figure 4-2 shows a simple block
diagram. The 4-layer board provides a flexible power supply, 36 pushbutton matrix, 128x32 LCD,
Touchpad sensor, 3-axis accelerometer, four indicator LEDs, buzzer, and a USB <> UART serial port.
As the board name implies this platform is useful to develop an RF remote control application for a DTV,
entertainment console, or similar function. The 1323x-MRB provides the RF node and an IR transmitter
is available to support legacy IR protocol remote controls. The rich set of peripherals of the 1323x-RCM
allows a user to develop a remote control ranging from a simple input device to a higher end unit with
display.

4.2.1 Power Management
The 1323x-RCM can be powered from two AA batteries, the USB connector 5 V supply, or an external
DC supply and is also intended to power the 1323x-MRB. Figure 4-3 shows the power management
circuit.
Figure 4-3. 1323x-RCM Power Management Circuit
A boost-buck voltage regulator U8 is used in this design to allow operation over a relatively wide, low
voltage input range, i.e., the TPS63001 regulator has an input voltage range from 1.8 V to 5.5V. This
allows a broad range of power supply sources. The regulated output voltage of the TPS63001 is 3.3 V
which delivers about 3.05 V to the board due to the drop across the isolation Schottky diodes.
Attributes of the power management circuit include:
• Switch SL1 provides an ON/OFF function for all input voltage sources
• Red LED5 provides a POWER-ON indicator for all sources
• The 1323x-RCM can derive power from three different sources -
1. USB port Type-B connector J15 - power can be supplied from an actual USB port connection
or from an AC to DC converter that uses the USB connector to supply power.

2. External DC source via header J14 - a standard 0.1 in. spacing 1x2 pin header allows for
connection of an external DC supply.
3. Battery Operation - a battery holder that accommodates two AA batteries is mounted on the
non-component (back) side of the board and provides for battery operation.
– If either the USB or external DC source is present, the battery source is disabled by
MOSFET transistor Q3
– The sources are all isolated and protected by Schottky diodes
– The minimum effective battery operating voltage is controlled by the use the FTDI
FT232RQ USB <> UART device - leakage current back through the FT232RQ UART
connections to the MC13233 on the MRB can cause the Q3 MOSFET to partially turnoff at
battery voltage below approximately 2.7-2.8 Vdc.
NOTE
To avoid current leakage through the USB device and to have lowest
minimum battery operating voltage for battery-only operation, remove the
following jumpers:
• P1, Pins 7-8
• P1, Pins 11-12
• P1, Pins 17-18
• P1, Pins 21-22
NOTE
When battery operation is used, the temperature range of the two board
system should be limited to within the specified temperature range of the
battery technology. Table 4-1 limits temperature range from 0 °C to +50 °C
when battery operation is applied.
Table 4-2 lists the voltage source attributes.
