External System Interfaces

Host HCI Transport (UART)

The high speed UART interface provides the physical transport between the SiW3500 and the application host for the

transfer of Bluetooth data compliant with the Bluetooth specification. The table below shows the supported configura-

tions. The default baud rate is 115,200 bps and can be set depending on the product.

Host HCI Transport (3-Wire UART)

To reduce the number of signals and to increase the reliability of the HCI UART interface, a 3-wire UART protocol is

available in the SiW3500. The protocol is compliant with the Bluetooth specification H:5 transport and backwards

compatible with the BCSP 3-wire UART protocol. Selection between H:4 UART, H:5 UART, and BCSP UART is done

automatically by the SiW3500.

Audio Codec Interface

The SiW3500 supports direct interface to an external audio CODEC or PCM host device. The interface provides the

following configurations:

• Standard PCM clock rates from 64 kHz to 2.048 MHz with multi-slot handshakes and synchronization.

• Supports either master or slave mode.

• Supports any PCM data size up to 16 bits.

• Compatible with Motorola SSI mode.
