Pin No. Pin Name Type Descriptions
1 BT_VCC Power DC Power Supply 3.3V±5%
2 BT_USBN In/Out Host USB Differential Data
3 PCM_OUT Out PCM Data Output — serial PCM data output to the PCM Codec.
This data is synchronous with PCM_BCLK, and the first serial bit is qualified by PCM_SYNC.
4 BT_USBP In/Out Host USB Differential Data
5 PCM_IN In PCM Data Input — serial PCM data from the PCM Codec.
This data is clocked in with PCM_BCLK, and the first serial bit is qualified by PCM_SYNC.
6 BT_GND Ground Digital Ground
7 BT_GND Ground Digital Ground
8 PCM_CLK In/Out NC PIN
9 PCM_CLK In/Out In master mode, this is the clock output used by the PCM Codec to clock CM_OUT into the Codec.
In clock slave mode, this is an input.
10 -IOWE NC NC PIN
11 PCM_SYNC In/Out PCM Sync Signal (Slot 0) — In master mode, this is an 8 kHz sync signal for channel 0 that synchronizes the input and output serial data streams of the Codec. In slave mode, this is an input.
12 BT_WAKE Output Bluetooth device wake-up: Signal from the host to the Bluetooth device that the host requires attention.
Asserted = Bluetooth device must wake-up or remain awake.
Deasserted = Bluetooth device may sleep when sleep criteria are met.
