6. HOST INTERFACE TIMING CHARACTERISTICS

The following table summarizes the Host Controller interface options. All interfaces operate

independently.

WLAN

Shared HCI for all functional

blocks except WLAN

BT Voice/Audio

WLAN HS SDIO Over UART BT PCM

The device incorporates UART module dedicated to the BT shared-transport Host Controller

Interface (HCI) transport layer. The HCI interface is used to transport commands, events and ACL

between the Bluetooth device and its host using HCI data packets. This acts as a shared transport

for all functional blocks except WLAN.

WLAN SDIO Transport Layer

The SDIO is the host interface for WLAN. The interface between the host and the module uses

an SDIO interface and supports a maximum clock rate of 50MHz.

The Device SDIO also supports the following features of the SDIO V3 specification:

 4 bit data bus

 Synchronous and Asynchronous In-Band-Interrupt

 Default and High-Speed (HS, 50MHz) timing

 Sleep/wake commands
