Syn chron ous Serial I nt erface
This interface is a synchronous serial port interface (SPI) for interfacing with other digital devices. The
SPI port can be used for system debugging. It can also be used for programming the Flash memory.
UART
This interface is a standard Universal Asynchronous Receiver Transmitter (UART) interface for
communicating with other serial devices.
PCM / I
2
S / SPDI F I nt e rfa ce
This interface is a bi-directional serial programmable audio interface supporting PCM, I2S and SPDIF
formats.
Audio I n t e rface
The audio interface of TBM–CBC5 has fully differential inputs and outputs and a microphone bi
as output. A
high-quality stereo audio Bluetooth application can be implemented with minimum amount of external
components.
Pr ogr am m a ble I / O
BTP518B has a total of 10 digital programmable I/O terminals. These are controlled by the firmware running
on the device.
Reset
TBM–CBC5 has a reset circuitry that is used to reset the module in the startup to ensure proper operation of
the flash memory. Alternatively, the reset can be externally driven by using a TBM–CBC5 reset pin.

Dedicated hardware is provided to implement a variety of coexistence schemes. Channel skipping AFH
(Adaptive Frequency Hopping), priority signaling, channel signaling, and host passing of channel
instructions are all supported. The features are configured in firmware. Since the details of some
methods are proprietary (e.g. Intel WCS)
