7. PHYSICAL INTERFACES
7.1 UART Interface
WT11 Universal Asynchronous Receiver Transmitter (UART) interface provides a simple
mechanism for communicating with other serial devices using the RS232 standard1.
UART_TX
UART_RX
UART_RTS
UART_CTS
WT12
Figure 6: WT11 UART interface
Four signals are used to implement the UART function, as shown in Figure 11.12. When
WT11 is connected to another digital device, UART_RX and UART_TX transfer data
between the two devices. The remaining two signals, UART_CTS and UART_RTS, can be
used to implement RS232 hardware flow control where both are active low indicators. All
UART connections are implemented using CMOS technology and have signaling levels of
0V and VDD_PADS.
Notes:
In order to communicate with the UART at its maximum data rate using a standard PC, an
accelerated serial port adapter card is required for the PC.

UART Configuration While RESET is Active
The UART interface for WT11 while the chip is being held in reset is tri-state. This will
allow the user to daisy chain devices onto the physical UART bus. The constraint on this
method is that any devices connected to this bus must tri-state when WT11reset is de-
asserted and the firmware begins to run.
7.2 USB Interface
WT11 USB devices contain a full speed (12Mbits/s) USB interface that is capable of driving
a USB cable directly. No external USB transceiver is required. The device operates as a
USB peripheral, responding to requests from a master host controller such as a PC. Both
the OHCI and the UHCI standards are supported. The set of USB endpoints implemented
can behave as specified in the USB section of the Bluetooth v2.0 + EDR specification or
alternatively can appear as a set of endpoint appropriate to USB audio devices such as
speakers.
As USB is a Master/Slave oriented system (in common with other USB peripherals), WT11
only supports USB Slave operation.
7.2.1 USB Data Connections
The USB data lines emerge as pins USB_DP and USB_DN. These terminals are connected
to the internal USB I/O buffers of the WT11 and therefore have low output impedance. To
match the connection to the characteristic impedance of the USB cable, resistors are
included with USB_DP / USB_DN and the cable.
7.2.2 USB Pull-Up Resistor
WT11 features an internal USB pull-up resistor. This pulls the USB_DP pin weakly high
when
WT11 is ready to enumerate. It signals to the PC that it is a full speed (12Mbit/s) USB
device. The USB internal pull-up is implemented as a current source, and is compliant with
Section 7.1.5 of the USB specification v1.2. The internal pull-up pulls USB_DP high to at
least 2.8V when loaded with a 15k: r5% pull-down resistor (in the hub/host) when VDD
=3.3V. This presents a Therein resistance to the host of at least 900Ohms. Alternatively,
an external 1.5k: pull-up resistor can be placed between a PIO line and D+ on the USB
cable. The firmware must be alerted to which mode is used by setting PS Key
PSKEY_USB_PIO_PULLUP appropriately. The default setting uses the internal pull-up
resistor.
7.2.3 Power Supply
The USB specification dictates that the minimum output high voltage for USB data lines is
2.8V. To safely meet the USB specification, the voltage on the VDD_USB supply terminals
must be an absolute minimum of 3.1V. CSR recommends 3.3V for optimal USB signal
quality.
7.2.4 Detach and Wake-Up Signaling
WT11 can provide out-of-band signaling to a host controller by using the control lines
called ‘USB_DETACH’ and ‘USB_WAKE_UP’. These are outside the USB specification (no
wires exist for them inside the USB cable), but can be useful when embedding WT11 into a
circuit where no external USB is visible to the user. Both control lines are shared with PIO
pins and can be assigned to any PIO pin by setting the PS Keys PSKEY_USB_PIO_DETACH
22
and PSKEY_USB_PIO_WAKEUP to the selected PIO number.
USB_DETACH is an input which, when asserted high, causes WT11 to put USB_DN and
USB_DP in high impedance state and turned off the pull-up resistor on D+. This detaches
the device from the bus and is logically equivalent to unplugging the device. When
USB_DETACH is taken low, WT11 will connect back to USB and await enumeration by the
USB host.
USB_WAKE_UP is an active high output (used only when USB_DETACH is active) to wake
up the host and allow USB communication to recommence. It replaces the function of the
software USB WAKE_UP message (which runs over the USB cable), and cannot be sent
while WT11 is effectively disconnected from the bus.
Figure 7: USB_DETACH and USB_WAKE_UP Signal
7.2.5 USB Driver
A USB Bluetooth device driver is required to provide a software interface between WT11
and Bluetooth software running on the host computer. Suitable drivers are available from
www.bluegiga.com/techforum/.
7.2.6 USB 1.1 Compliance
WT11 is qualified to the USB specification v1.1, details of which are available from
http://www.usb.org. The specification contains valuable information on aspects such as
PCB track impedance, supply inrush current and product labeling.
Although WT11 meets the USB specification, CSR cannot guarantee that an application
circuit designed around the chip is USB compliant. The choice of application circuit,
component choice and PCB layout all affect USB signal quality and electrical characteristics.
The information in this document is intended as a guide and should be read in association
with the USB specification, with particular attention being given to Chapter 7. Independent
USB qualification must be sought before an application is deemed USB compliant and can
bear the USB logo. Such qualification can be obtained from a USB plug fest or from an
independent USB test house.
Terminals USB_DP and USB_DN adhere to the USB specification 2.0 (Chapter 7) electrical
requirements.
7.2.7 USB 2.0 Compatibility
WT11 is compatible with USB v2.0 host controllers; under these circumstances the two
ends agree the mutually acceptable rate of 12Mbits/s according to the USB v2.0
specification.
7.3 SPI Interface
The synchronous serial port interface (SPI) for interfacing with other digital devices. The
SPI port can be used for system debugging. It can also be used for programming the Flash
memory. SPI interface is connected using the MOSI, MISO, CSB and CLK pins.
7.4 I/O Parallel Ports
The Parallel Input Output (PIO) Port is a general-purpose I/O interface to WT11. The port
23
consists of six programmable, bi-directional I/O lines, PIO[2:7].
Programmable I/O lines can be accessed either via an embedded application running on
WT11 or via private channel or manufacturer-specific HCI commands.
All PIO lines are configured as inputs with weak pull downs at reset.
PIO[2] / USB_PULL_UP (1)
This is a multifunction terminal. The function depends on whether WT11 is a USB or UART
capable version. On UART versions, this terminal is a programmable I/O. On USB versions,
it can drive a pull-up resistor on USB_D+. For application using external RAM this terminal
may be programmed for chip select.
PIO[3] / USB_WAKE_UP (1)
This is a multifunction terminal. On UART versions of WT11 this terminal is a
programmable I/O. On USB versions, its function is selected by setting the Persistent
Store Key PSKEY_USB_PIO_WAKEUP (0x2cf) either as a programmable I/O or as a
USB_WAKE_UP function.
PIO[4] / USB_ON (1)
This is a multifunction terminal. On UART versions of WT11 this terminal is a
programmable I/O. On USB versions, the USB_ON function is also selectable.
PIO[5] / USB_DETACH (1)
This is a multifunction terminal. On UART versions of WT11 this terminal is a
programmable I/O. On USB versions, the USB_DETACH function is also selectable.
PIO[6] / CLK_REQ
This is multifunction terminal, its function is determined by Persistent Store Keys. Using
PSKEY_CLOCK_REQUEST_ENABLE, (0x246) this terminal can be configured to be low
when WT11 is in deep sleep and high when a clock is required. The clock must be supplied
within 4ms of the rising edge of PIO[6] to avoid losing timing accuracy in certain Bluetooth
operating modes.
PIO[7]
Programmable I/O terminal.
8. RESET
The RESET pin is an active high reset and is internally filtered using the internal low
frequency clock oscillator. A reset will be performed between 1.5 and 4.0ms following
RESET being active. It is recommended that RESET be applied for a period greater than
5ms.
24
9. SOFTWARE STACKS
WT11 is supplied with Bluetooth v2.0 + EDR compliant stack firmware, which runs on the
internal RISC microcontroller.
The WT11 software architecture allows Bluetooth processing and the application program
to be shared in different ways between the internal RISC microcontroller and an external
host processor (if any). The upper layers of the Bluetooth stack (above HCI) can be run
either on-chip or on the host processor.

Figure 8: WRAP THOR VM Stack
In figure above, the iWRAP software solution is described. In this version of the stack
firmware shown no host processor is required to run the Bluetooth protocol stack. All
software layers, including application software, run on the internal RISC processor in a
protected user software execution environment known as a Virtual Machine (VM).
The host processor interfaces to iWRAP software via one or more of the physical interfaces
which are also shown in the figure above. The most common interfacing is done via UART
interface using the ASCII commands supported by the iWRAP software. With these ASCII
commands the user can access Bluetooth functionality without paying any attention to the
complexity which lies in the Bluetooth protocol stack.
The user may write applications code to run on the host processor to control iWRAP
software with ASCII commands and to develop Bluetooth powered applications.

More details of iWRAP software and it’s features can be found from iWRAP User Guide
which can be downloaded from www.bluegiga.com.
10. SOLDERING
10.1 Reflow Soldering
The soldering profile depends on various parameters necessitating a set up for each
application. The data here is given only for guidance on solder re-flow. There are four
zones:
1. Preheat Zone - This zone raises the temperature at a controlled rate, typically 1-
2.5°C/s.
2. Equilibrium Zone - This zone brings the board to a uniform temperature and also
activates the flux. The duration in this zone (typically 2-3 minutes) will need to be
adjusted to optimize the out gassing of the flux.
3. Reflow Zone - The peak temperature should be high enough to achieve good
wetting but not so high as to cause component discoloration or damage. Excessive
soldering time can lead to intermetallic growth which can result in a brittle joint.
4. Cooling Zone - The cooling rate should be fast, to keep the solder grains small
which will give a longer lasting joint. Typical rates will be 2-5°C/s.
5. Solder Re-Flow Profile for Devices with Lead-Free Solder Balls
Composition of the solder ball: Sn 95.5%, Ag 4.0%, Cu 0.5%
Key features of the profile:
Initial Ramp = 1-2.5°C/sec to 175°C±25°C equilibrium
Equilibrium time = 60 to 180 seconds
Ramp to Maximum temperature (250°C) = 3°C/sec max.
Time above liquidus temperature (217°C): 45-90 seconds
Device absolute maximum reflow temperature: 260°C
Devices will withstand the specified profile. Lead-free devices will withstand up to three
reflows to a maximum temperature of 260°C.

Certifications
WT11 is compliant to the following specifications
10.2 Bluetooth
The WT11-E module is Bluetooth qualified and listed as an end product. If not modified in
any way, it is a complete Bluetooth entity, containing software and hardware functionality
as well as the whole RF-part including the antenna. This practically translates to that if the
module is used without modification of any kind, it does not need any Bluetooth approval
work. If changes are made in the parameter set, added profiles or in the antenna design,
it is required to be submitted to a BQB (Bluetooth Qualification Body) for evaluation on
what needs to be tested.
With HCI firmware WT11 will not meet the requirements of end product qualification.
