No part of this technical document can be reproduced in any form without permission of USI. 3 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 receive switch. PIO[1] / TX 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 • Laptop and Desktop PCs • Mobile Phones • Cordless Headsets • Personal Digital Assistants (PDAs) • Computer Accessories (USB Dongles) • Mice, Keyboards and Joysticks • Digital Cameras and Camcorders • Domestic and Industrial Appliances • FAX • Printers • Scanners

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. PIO[7] ~ PIO[11] Programmable Input/Output terminal. 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.

No part of this technical document can be reproduced in any form without permission of USI. 5 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. Figure 4. Self-Powered Mode Bus-Powered Mode Rs=24 Ohm, series damping resistor. Already included in module. Rvb1 = 47K Ohm, 5%. VBUS ON sense divider. Rvb2 = 22K Ohm, 5%. VBUS ON sense divider. Rvb1 and Rvb2 must added by user under self-powered mode.

No part of this technical document can be reproduced in any form without permission of USI. 6 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. Figure 5. USB_DETACH and USB_WAKE_UP Signal

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. Figure 7.

No part of this technical document can be reproduced in any form without permission of USI. 9 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 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

No part of this technical document can be reproduced in any form without permission of USI. 11 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). PCM Timing Information - PCM Master Timing

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) Parameter Possible Values Minimum 1200 Baud (<2% Error) Baud Rate Default 115.2KBaud (<1% Error) Maximum 1.5MBaud (<1% Error) Flow Control RTS/CTS or None Parity None, Odd or Even Number of Stop Bits 1 or 2 Bits per channel 8 Please specify your needs when ordering the modules with UART interface.

No part of this technical document can be reproduced in any form without permission of USI. 19 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.
