SiW3500

Preliminary

• Configuration of the CODEC interface is done by the firmware during boot-up by reading non-volatile memory (NVM)

parameters.

Multi-function I/Os (MFPs)

Up to 8 (eight) multi-function I/O ports are available in the SiW3500. The table below identifies the I/Os and their usage.

Address A[18], SYNC_CLOCK, AUX_RTS, General purpose.

FREQ_SEL[3], SYNC_DATA, General purpose.

FREQ_SEL[1], General purpose.

FREQ_SEL[2], General purpose.

AUX_RXD, General purpose.

AUX_CTS, TX_RX_SWITCH, General purpose.

External Memory Interface

The SiW3500 does not require additional memory for standard below HCI protocol functions. An external memory

interface is available for execution of protocol stack software from FLASH memory if desired. If external FLASH memory

will be used, the read access time of the device must be 100 ns or less.

Auxiliary UART

The SiW3500 can be configured and enabled with an auxiliary UART port. This UART port can be used for debug

depending on the application software.

External Power Amplifier Interface

The SiW3500 supports the use of an external power amplifier for +20 dBm designs. When enabled, these signals

provide an integrated interface for the control of an external PA.

Signal

TX_RX_SWITCH

Description

Power control to external PA. This output provides a variable current source

that can be used to control the external PA. Leave unconnected if not used

Output signal used to indicate the state of the radio. This could be used as a

direction control for the PA. The polarity is programmable with the default set

as: Low = Transmit; High = Receive.

Power Management

The HOST_WAKEUP and EXT_WAKE signals are used for power management control of the SiW3500.

HOST_WAKEUP is an output signal used to indicate Bluetooth activity to the host. EXT_WAKE is an input signal used

by the host to wake up the SiW3500 from sleep mode.

For control of the reference clock source, CLOCK_REQ_IN and CLOCK_REQ_OUT can be made available to turn on/off

an external reference clock source.

General-Purpose Analog to Digital Converter (ADC)

The SiW3500 incorporates a general-purpose ADC that can be enabled to sample external analog voltage. The ADC

has an 8-bit resolution.

External EEPROM Controller and Interface

This interface is intended for communication to an optional EEPROM when using the SiW3500 in ROM mode. The
