5 WLAN External Host Interfaces

For connection to a host processor, the W2CBW00DI supports the Secure Digital Input Output (SDIO) and Generic SPI (G-SPI) interfaces for WLAN. The choice of interface is dependent on the required data throughput, with SDIO having a throughput that is approximately four times greater than G-SPI.

If the WLAN SDIO interface is selected for connection to a host processor, then the host processor must support SDIO – (SD is not sufficient). If the selected processor does not have an integrated SDIO controller, then an external SDIO bridge can be used (e.g. SDIO-PCI Bridge for interfacing with a process supporting PCI interface only).

If the WLAN G-SPI interface is selected for connection to a host processor, then the host processor must support G-SPI – (SPI is not sufficient). If the selecte d processor only has SPI, then it might be possible to implement G-SPI with a combination of the SPI and a GPIO pin for interrupt. If the selected processor does not have SPI interface, then it might be possible to implement a G-SPI interface using a combination of GPIO pins. Please contact your sales representative if your processor does not support SDIO or G-SPI interfaces.

5.1 SDIO Interface

W2CBW00DI supports SDIO device interface that conforms to the industry standard SDIO FullSpeed card specification and allows a host controller using the SDIO bus protocol to access the WLAN device. The SDIO interface contains interface circuitry between an external SDIO bus and the internal shared bus.

W2CBW00DI acts as a device on the SDIO bus. The host unit can access registers of the SDIO interface directly and can access shared memory in the device through the use of BARs and a DMA engine.

The SDIO device interface main features include:

•

On-chip memory used for CIS

•

Supports SPI, 1-bit SDIO, and 4-bit SDIO transfer modes at the full clock range of 0 to 50 MHz

•

Special interrupt register for information exchange

5.3 G-SPI Interface

W2CBW00DI supports a generic, half-duplex, DMA-assisted G-SPI host interface (G-SPI) that allows a host controller using a Generic SPI bus protocol to access the WLAN de vice. The G-SPI interface contains interface circuitry between an external G-SPI bus and the internal shared bus.

The 88W8688 acts as the device on the G-SPI bus. The host unit can access the G-SPI registers directly and can access shared memory in the device through the use of BARs and a DMA engine.

The G-SPI unit supports Generic SPI Interface protocols as detailed in the following sections. The design is capable of 50 MHz operation. The interface supports the following functionality:

6 Bluetooth External Interfaces

For connection to a host processor, the W2CBW00DI supports UART interface. There is also a PCM interface for connection to audio PCM devices such analog to digital and digital to analog converters. The PCM selec tio n i s m ade in f ir mw ar e.

6.1 UART Interface

W2CBW00DI UART interface provides a simple mechanism for communicating with other serial device s using the RS232 standard. Four signals are us ed to implemen t the UART func tion:

•

BT_UART_TX

•

BT_UART_RX

•

BT_UART_RTS

•

BT_UART_CTS

•

BT_UART_DSR

•

BT UART DTR

When W2CBW00DI is connected to another digital device, BT_UART_RX and BT_UART_TX transfer data between the two devices. The remaining two signals, BT_UART_CTS and BT_UART_RTS, can be used to implement RS232 hardware flow control where both are active low indicators.

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. An external RS232 transceiver ch ip is also needed.

The UART interface is capable of resetting W2CBW00DI upon reception of a break signal.

6.2 PCM Interface

Pulse Code Modulation (PCM) is a standard method used to digitize audio (particularly voice) patterns for transmission over digital communication channels. Through its PCM interface, W2CBW00DI has hardware suppor t for co ntinu al transmission and reception of PCM data, so reducing processor overhead for wireless headset applications. W2CBW00DI offers a bi-directional digital audio interface that routes directly into t h e baseband layer of the on-chip firmware. It does not pass t hr oug h t he H CI p rot oco l l aye r. Hardware on W2CBW00DI 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.

W2CBW00DI 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. W2CBW00DI 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

-law or A-law compounded sample formats at 8k samples/s, and

can receive and transmit on any selection of three of the first four slots following PCM_SYNC.

7 Antenna and Clock

W2CBW00DI has two antenna interfaces, one for Bluetooth and one for WLAN. Both of these interfaces have 50 Ohm impedance.

W2CBW00DI has an internal crystal oscillator with 38.4 MHz frequency (frequency stability +/20ppm) and requires no external clock source. This crystal provides clock for both WLAN and Bluetooth.

part developer can create for a fixed NRE. This driver is specific to the operating system, processor and host bus – it cannot be used for any other processors, operating systems or host buses. Since the operating system and platform matrix is quite large, it is not possible to have all the combinations off the shelf. Please contact your sales represen tative on the actual driver availability.

The following is a brief description of the driv er features along with the processors, operating systems and host buses.

8.2 Bluetooth

Bluetooth portion of W2CBW00DI needs stack and profiles for operation. It uses a st andard HCI interface – any commercial stack or profile supporting the st andard interface will work with W2CBW00DI.

WinCE, WinMobile and Vista 32 bit have embedded stack and basic profiles that work with W2CBW00DI. Advanced profiles for these operating systems can be procured from commercial vendors like IV T, iAnywhere and Toshiba.

Wi2Wi will work with the customers to provide a suitable solution for the stack and profiles. There may be some additional cost associated with this based on the requirements. Please contact your sales representative to get more details.

9.1 Host Processor

The TCP/IP stack, Ethernet Driver and the 802.11 extensions reside on the host processor. The Hardware Interface Driver, which can be G-SPI or SDIO, is partitioned between the host and the firmware on the WiFi.

The WLAN firmware for the WiFi is downloaded through the selected host interface (G-SPI or SDIO) by the Hardware Interface Driver at power up.

Once the firm ware is dow nlo aded, the Dat a Pa th and th e Con trol Path bet ween th e host and W iFi are established, and information can flow between the two devices.
