TRSF1602B General Description：
The TxP16S2TM is a high performance 16-bit MCU, running up to 13MHz and provided with 128K FLASH and total 3K SRAM for high performance process of audio algorithm. It is the new generation computational kernel for Flash Speech series. It has initially aimed at the areas of speech application to demonstrate its profession. TxP16S2 furnish with a fast unit, which allows calculation instructions to be issued with access memory simultaneously during one cycle. The TRSF1602B is equipped with TxP16S2 and integrating input/output ports,Audio PWM, Timer and Low Voltage Reset...etc. on a chip.
Furthermore, TRSF1602B extend its external device connection capability such as Serial ROM/Flash. The internal memory capacity includes 128Kx16 program/data FLASH plus 3Kx16 working SRAM.

TRSF1602B MAC (16-bit X 16-bit Multiplier and Accumulator)：
A 16 bit x 16 bit MAC is provided for digital signal processing. The core of MAC operation is multiply MX&MY
with 2’S complement operand and accumulation previous 40-bit MF then rounding store result in the 40-bit MR
register. The basic MAC architecture is shown as Figure 5.5.
TRSF1602B Application Circuit and Chip Power Circuit：
Application Circuit: Mono16-bit PWM output
Notice:
1. VCC Decoupling Cap 10uF should be close to IC within 0.5cm.
2. VCC Decoupling Cap 0.1uF should be close to IC within 0.5cm.
