b) A critical component is any component of a life support device or system whose failure to perform
can be reasonably expected to cause the failure of the life support device or system, or to affect
its safety or effectiveness.
Laird Technologies does not assume responsibility for use of any of the circuitry described, no circuit
patent licenses are implied and Laird Technologies reserves the right at any time to change without notice
said circuitry and specifications.
6.12 Data Sheet Status
Laird reserves the right to change the specification without prior notice in order to improve the design and
supply the best possible product.
6.13 Changes between release
Although every effort is made to ensure compatibility, the functionality of some features has changed due
to the evolution of the Bluetooth chips and stack implementations. Users migrating between firmware
variants should check the following differences:
 ATZ
 AT+BTIN
Please check with Laird Technologies Ltd for the most recent data before initiating or completing a design.
7. PCM CODEC INTERFACE
PCM_OUT, PCM_IN, PCM_CLK, and PCM_SYNC carry up to three bi-directional channels of voice data,
each at 8ksamples/s. The format of the PCM samples can be 8-bit A-law, 8-bit μ-law, 13-bit linear, or 16-
bit linear. The PCM_CLK and PCM_SYNC terminals can be configured as inputs or outputs, depending
on whether the module is the master or slave of the PCM interface.
Contact a Laird FAE for further details.
The module is compatible with the Motorola SSI TM interface and interfaces directly to PCM audio
devices including the following:
7.1 Compatible Codec Chips
 Winbond W61360 13-bit linear CODEC (Motorola MC145483 compatible)
 OKI MSM7702 single channel A-law and μ-law CODEC
The default codec support is for the Winbond W61360.
