* Power Supply Specification
The power of DC3.1V ~ 3.6V is should be supplied to the Bluetooth module power(VDD). The
module supplies the power to the each block depending on the function. Module input power in
excess of the rated input power may cause damage to the internal components. And the influx of
Surge and ESD also may lead to the damage of the modem in the vehicle. For the prevention of this,
the module is necessary to design block the infloux of Sugre and EDS.

*Memory Interface
①Memory Management Unit
The MMU provides a number of dynamically allocated ring buffers that hold the data that is in transit
between the host, the air or the Kalimba DSP. The dynamic allocation of memory ensures efficient
use of the available RAM and is performed by a hardware MMU to minimise the overheads on the
processor during data/voice transfers.
②System RAM
48Kbyte of on-chip RAM supports the RISC MCU and is shared between the ring buffers used to
hold voice/data for each active connection and the general-purpose memory required by the
Bluetooth stack.
③Kalimba DSP RAM
Additional on-chip RAM is provided to support the Kalimba DSP:
■16K x 24-bit for data memory 1 (DM1)
■12K x 24-bit for data memory 2 (DM2)
■6K x 32-bit for program memory (PM)
Parameter Value
Baud rate 115,200 baud
Flow control None
Parity None
Number of stop bits 1
Bits per byte 8
* UART Interface
RBFA-C21XX UART interface provides a simple mechanism for communicating with other serial
devices using the RS232 protocol. UART configuration parameters, such as baud rate and packet
format, are set using LGIT firmware.
