7 WLAN External Interfaces
W2CBW003 supports SDIO and G-SPI interfaces for WLAN.
7.1 SDIO Interface
W2CBW003 supports SDIO device interface that conforms to the industry standard SDIO Full-Speed
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.
W2CBW003 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:
x On-chip memory used for CIS
x Supports SPI, 1-bit SDIO, and 4-bit SDIO transfer modes at the full clock range of 0 to 50 MHz
x Special interrupt register for information exchange
x Allows card to interrupt host

7.2 G-SPI Interface
W2CBW003 supports a generic, half-duplex, DMA-assisted SPI host interface (G-SPI) that allows a
host controller using a generic SPI bus protocol to access the WLAN device. The G-SPI interface
contains interface circuitry between an external SPI bus and the internal shared bus.
The 88W8686 acts as the device on the 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.

Dated: October 20, 2006
The 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:
SPI unit bus device operation
SPI unit register read / write
Interrupt generation to internal CPU
Interrupt generation to the SPI unit host
DMA to internal memories
Wake Interrupt to the Power Management Unit
8 Bluetooth External Interfaces
W2CBW003 supports UART, USB, PCM and SPI interfaces for Bluetooth.
8.1 UART Interface
W2CBW003 UART interface provides a simple mechanism for communicating with other serial devices
using the RS232 standard. Four signals are used to implement the UART function:
BT_UART_TX
BT_UART_RX
BT_UART_RTS
BT_UART_CTS
When W2CBW003 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. UART
configuration parameters, such as Baud rate and packet format, are set using W2CBW003 PS keys.
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 chip is also needed.

The UART interface is capable of resetting W2CBW003 upon reception of a break signal. A break is
identified by a continuous logic low (0V) on the BT_UART_RX.

PS Key “PSKEY_UART_BAUD_RATE (0x204)” can be used to set the desired Baud Rate for UART.
8.2 USB Interface
W2CBW003 contains 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 UHCI standards are
supported. The set of USB endpoints implemented can behave as specified in the USB section of the
Bluetooth Specification v2.0 + EDR or alternatively can appear as a set of endpoints appropriate to USB
audio devices such as a set of USB speakers.
USB is a master/slave oriented system (in common with other USB peripherals). W2CBW003 only
supports USB slave operation.
8.3 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, W2CBW003 has
hardware support for continual transmission and reception of PCM data, so reducing processor overhead
for wireless headset applications. W2CBW003 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 W2CBW003 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.
W2CBW003 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.
W2CBW003 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 ȝ-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 PS Key PS KEY_PCM_CONFIG.

W2CBW003 interfaces directly to PCM audio devices including the following:
x Qualcomm MSM 3000 series and MSM 5000 series CDMA baseband devices
x OKI MSM7705 four channel A-law and ȝ-law CODEC
x Motorola MC145481 8-bit A-law and ȝ-law CODEC
x Motorola MC145483 13-bit linear CODEC
x STW 5093 and 5094 14-bit linear CODECs
x W2CBW003 is also compatible with the Motorola SSI. interface
8.4 SPI Interface
W2CBW003 uses a 16-bit data and 16-bit address serial peripheral interface. Transactions may occur
when the internal processor is running or is stopped. This section describes the considerations required
when interfacing to W2CBW003 via the four dedicated serial peripheral interface terminals. Data can be
written or read one word at a time or the auto increment feature can be used to access blocks of data.
9 Antenna and Clock
W2CBW003 has two antenna interfaces, one for Bluetooth and one for WLAN. Both of these interfaces
have 50 Ohm impedance.
W2CBW003 has an internal crystal oscillator with 26 MHz frequency (frequency stability +/- 20ppm)
and requires no external clock source. This crystal provides clock for both WLAN and Bluetooth.

that is powered ON with any
materials that will reduce air
circulation such as a carrying
bag.
 
Transportation Precautions
To prepare the UMPC for transport, you should turn it OFF and disconnect all
external peripherals to prevent damage to the connectors. The hard disk drive’s
head retracts when the power is turned OFF to prevent scratching of the hard disk
surface during transport. Therefore, you should not transport the UMPC while the
power is still ON.
Cover Your UMPC
You can purchase an optional carrying case to protect it from dirt, water, shock, and
scratches.
CAUTION: The UMPC’s surface is easily dulled if not properly cared for. Be careful not
to rub or scrape the UMPC surfaces when transporting your UMPC.
Charge Your Batteries
If you intend to use battery power, be sure to fully charge your battery pack and any
optional battery packs before going on long trips. Remember that the power adapter
charges the battery pack as long as it is plugged into the computer and an AC power
source. Be aware that it takes much longer to charge the battery pack when the UMPC
is in use.
Airplane Precautions
Contact your airline if you want to use the UMPC on the airplane. Most airlines will
have restrictions for using electronic devices. Most airlines will allow electronic use only
between and not during takeoffs and landings.
CAUTION: There are three main types of airport security devices: X-ray machines
(used on items placed on conveyor belts), magnetic detectors (used on people walking
through security checks), and magnetic wands (hand-held devices used on people
or individual items). You can send your UMPC and diskettes through airport X-ray
machines. However, it is recommended that you do not send your UMPC or diskettes
through airport magnetic detectors or expose them to magnetic wands.
