General Applications
and more can be designed using this ready-to-use module as a surface mount component to enable a rapid
design cycle and short time-to-market.
The SPI (Serial Peripheral Interface) is used only for programming and testing the module. The PCM ports
are used to connect to an external CODEC to provide two-way audio communication or to a PCM audio
stream to and from the host. The HCI can be a standard four wire UART or a USB interface.
Device Terminal Functions
PIO
The Parallel Input Output (PIO) Port is a general-purpose input/output interface to/from BM-GP-CS-03. The
port consists of eight programmable, bi-directional I/O lines, PIO[0:7]. Programmable Input/Output can be
accessed either via an embedded application running on BM-GP-CS-03 or via private channel or
manufacturer-specific HCI commands.
PIO[0] / RXEN
This is a multifunction terminal. Its function is selected by setting the Persistent Store Key
PSKEY_TX/RX_PIO_CONTROL (0x209). It can be used as a programmable I/O, however it will normally be

used to control the radio front end transmit switch. Refer to CSR documentation for BlueCore2-External
software.
PIO[2] / USB_PULL_UP
This is a multifunction terminal. On UART versions of BM-GP-CS-03 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[3] / USB_WAKE_UP
This is a multifunction terminal. On UART versions of BM-GP-CS-03 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
This is a multifunction terminal. The function depends on whether BM-GP-CS-03 is being used with a USB or
UART connection. On UART versions, this terminal is a programmable Input/Output. For USB versions the
USB_ON function is also selectable.
PO[5] / USB_DETACH
This is a multifunction terminal. The function depends on whether BM-GP-CS-03 is being used with a USB or
UART connection.
On UART versions, this terminal is a programmable Input/Output. For USB versions the USB_DETACH
function is also selectable.
PIO[6]
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
BM-GP-CS-03 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.

USB Interface
BM-GP-CS-03 contains its own full-speed (12Mbits/s) USB interface. The silicon is compliant with USB
Specification 1.1, available from www.usb.org. Designers of circuits using the USB interface of
Class 2 Bluetooth Module (BM-GP-CS-03)
All rights are reserved by USI. No part of this technical document can be reproduced in any form without permission of

BM-GP-CS-03 are encouraged to read this specification, as it contains valuable information on aspects such
as PCB track impedance, supply inrush current and product labeling.
BM-GP-CS-03 operates as a peripheral USB device, responding to requests from a master host controller
such as a PC. Both the Open Host Control Interface (OHCI) and the Universal Host Control Interface (UHCI)
are supported (see Section H2 of the Bluetooth specification for more information). The set of USB endpoints
implemented behave as specified in the USB section of the Bluetooth specification v1.1, part H2.
As USB is a master-slave-orientated system, BM-GP-CS-03 only supports USB slave operation.
Power Supply
The minimum output high voltage for USB data lines is 2.8V. To safely meet the USB specification, the
voltage on terminals must be an absolute minimum of 3.1V. USI recommends 3.3V for optimal USB signal
quality.
Self-Powered Mode
In self-powered mode, the circuit is powered from its own power supply and not from the VBUS (5V) line of
the USB cable. It draws only a small leakage current (below 0.5mA) from VBUS on the USB cable. This is
the easier mode for which to design for, as the design is not limited by the power that can be drawn from the
USB hub or root port. However, it requires that VBUS be connected to BM-GP-CS-03 via a resistor network
(Rvb1 and Rvb2), so module can detect when VBUS is powered up. BM-GP-CS-03 will not pull USB_D+ high
when VBUS is off.
The terminal marked USB_ON can be any free PIO pin. The default is PIO[4]. The PIO pin selected must be
registered by setting PSKEY_USB_PIO_VBUS (0x2d1) to the corresponding pin number.

In bus-powered mode the application circuit draws its current from the 5V VBUS supply on the USB cable.
BM-GP-CS-03 negotiates with the PC during the USB enumeration stage about power consumption. The 5V
VBUS line emerging from a PC is often electrically noisy. As well as regulation down to 3.3V and 1.8V,
applications should include careful filtering of the 5V line to attenuate noise that is above the voltage
regulator’s bandwidth. Excessive noise on the 1.8V supply to the analogue supply pins of BM-GP-CS-03 will
result in reduced receive sensitivity and a distorted transmit signal.
Detach and Wake_Up Signaling
BM-GP-CS-03 can provide out-of-band signaling to a host controller by using the dedicated 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 BM-GP-CS-03 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 Persistent Store Keys PSKEY_USB_PIO_DETACH (0x2ce) and
PSKEY_USB_PIO_WAKEUP (0x2cf) to the selected PIO number).
USB_DETACH, is an input which, when asserted high, causes BM-GP-CS-03 to put USB_D- and USB_D+
in a high-impedance state and to 1.5K Ohm?pull-up resistor on USB_D+. This detaches the device from the
bus and is logically equivalent to unplugging the device. When USB_DETACH is taken low, BM-GP-CS-03
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 proper), and cannot be sent while BM-GP-CS-03 is effectively disconnected
from the bus.

USB Driver
A USB Bluetooth device driver is required to provide a software interface between BM-GP-CS-03 and
Bluetooth applications running on the host.
USB 1.1 Compliance
BM-GP-CS-03 is compatible with 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 BM-GP-CS-03 meets the USB specification,
USI 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. 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_D+ and USB_D- adhere to the USB specification 1.1 electrical requirements. For AC and DC
specifications for terminals USB_DETACH, USB_WAKE_UP, USB_PULL_UP and USB_ON, refer to PIO
specification.
USB 2.0 Compatibility
BM-GP-CS-03 is compatible with USB specification 2.0 masters; under these circumstances the two ends
agree the mutually acceptable rate of 12Mbits/s according to the USB 2.0 specification.
PCM
Pulse Code Modulation (PCM) is the standard method used to digitize human voice patterns for transmission
over digital communication channels. Through its PCM interface, BM-GP-CS-03 has hardware support for
continual transmission and reception of PCM data, thus reducing processor overhead for wireless headset
applications. BM-GP-CS-03 offers a bi-directional digital audio interface that routes directly into the
baseband layer of the on-chip firmware. It does not pass through the HCI protocol layer.
Hardware on BM-GP-CS-03 allows the data to be sent to and received from a SCO connection.
Up to three SCO connections can be supported by the PCM interface at any one time.
BM-GP-CS-03 can operate as the PCM interface Master generating an output clock of 128, 256 or 512kHz.
When configured as PCM interface slave it can operate with an input clock up to 2048kHz. BM-GP-CS-03 is
compatible with a variety of clock formats, including Long Frame Sync, Short Frame Sync and GCI timing
environments. It supports 13 or 16-bit linear, 8-bit u-law or A-law companded sample formats at 8ksamples/s

and can receive and transmit on any selection of three of the first four slots following PCM_SYNC. The PCM
configuration options are enabled by setting the Persistent Store Key PS KEY_PCM_CONFIG (0x1b3).
BM-GP-CS-03 interfaces directly to PCM audio devices includes the following:
l Qualcomm MSM 3000 series and MSM 5000 series CDMA baseband devices
l OKI MSM7705 four channel A-law and u-law CODEC
l Motorola MC145481 8-bit A-law and u-law CODEC
l Motorola MC145483 13-bit linear CODEC
l BM-GP-CS-03 is also compatible with the Motorola SSI TM interface
PCM Interface Master/Slave
When configured as the Master of the PCM interface, BM-GP-CS-03 generates PCM_CLK and PCM_SYNC.
Figure 6. BM-GP-CS-03 configured as PCM interface master
When configured as the Slave of the PCM interface, BM-GP-CS-03 accepts PCM_CLK rates up to 2048kHz.

Long Frame Sync
Long Frame Sync is the name given to a clocking format that controls the transfer of PCM data words or
samples. In Long Frame Sync, the rising edge of PCM_SYNC indicates the start of the PCM word. When
BM-GP-CS-03 is configured as PCM Master, generating PCM_SYNC and PCM_CLK, then PCM_SYNC is
8-bits long. When BM-GP-CS-03 is configured as PCM Slave, PCM_SYNC may be from two consecutive
falling edges of PCM_CLK to half the PCM_SYNC rate (i.e., 62.5s) long.
Figure 8. Long Frame Sync (Shown with 8-bit Companded Sample)
BM-GP-CS-03 samples PCM_IN on the falling edge of PCM_CLK and transmits PCM_OUT on the rising
edge. PCM_OUT may be configured to be high impedance on the falling edge of PCM_CLK in the LSB
position or on the rising edge.
Short Frame Sync
In Short Frame Sync the falling edge of PCM_SYNC indicates the start of the PCM word. PCM_SYNC is
always one clock cycle long.
Figure 9. Short Frame Sync (Shown with 16-bit Sample)
As with Long Frame Sync, BM-GP-CS-03 samples PCM_IN on the falling edge of PCM_CLK and transmits

PCM_OUT on the rising edge. PCM_OUT may be configured to be high impedance on the falling edge of
PCM_CLK in the LSB position or on the rising edge.
Multi-Slot Operation
More than one SCO connection over the PCM interface is supported using multiple slots. Up to three SCO
connections can be carried over any of the first four slots.
Figure 10. Multi-slot Operation with Two Slots and 8-bit Companded Samples
GCI Interface
BM-GP-CS-03 is compatible with the General Circuit Interface, a standard synchronous 2B+D ISDN timing
interface. The two 64Kbps B channels can be accessed when this mode is configured.
Figure 11. GCI Interface
The start of frame is indicated by the rising edge of PCM_SYNC and runs at 8kHz. With BM-GP-CS-03 in

Slave mode, the frequency of PCM_CLK can be up to 4.096MHz.
Slots and Sample Formats
BM-GP-CS-03 can receive and transmit on any selection of the first four slots following each sync pulse. Slot
durations can be either 8 or 16 clock cycles. Durations of 8 clock cycles may only be used with 8-bit sample
formats. Durations of 16 clocks may be used with 8, 13 or 16-bit sample formats. BM-GP-CS-03 supports
13-bit linear, 16-bit linear and 8-bit u-law or A-law sample formats. The sample rate is 8ksamples/s. The bit
order may be little or big endian. When 16-bit slots are used, the 3 or 8 unused bits in each slot may be filled
with sign extension, padded with zeros or a programmable 3-bit audio attenuation compatible with some
Motorola CODECs.
Figure 12. 16-bit Slot Length and Sample Formats
Additional Features
BM-GP-CS-03 has a mute facility that forces PCM_OUT to be 0. In Master mode, PCM_SYNC may also be
forced to 0 while keeping PCM_CLK running (which some CODECS use to control power-down).

UART Interface
BM-GP-CS-03 Universal Asynchronous Receiver Transmitter (UART) interface provides a simple mechanism
for communicating with other serial devices using the RS232 standard(1).
Figure 16. Universal Asynchronous Receiver
Four signals are used to implement the UART function, as shown in above figure. When BM-GP-CS-03 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.
UART configuration parameters, such as Baud rate and packet format, are set using PSTool software.
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.
Uses RS232 protocol but voltage levels are 0V to VDD_PADS, (requires external RS232 transceiver IC)

Impedance Matching of Antenna
BM-GP-CS-03 utilizes a mono-pole ceramic chip antenna for radio communication. Application environments,
such as notebooks, PDAs, headsets or other handheld devices, both have plastic housings, different
motherboards and other mechanism structures. These factors will cause the deviation of antenna resonant
frequency, but can be corrected by antenna matching. In order to achieve longest communication range, it is
recommended to optimize the antenna matching in the final product. Please consult USI for further information.
