CST1602A(C) General Description：
The CST16S2TM 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. CST16S2 furnish with a fast unit, which allows calculation instructions to be issued with access memory simultaneously during one cycle. The CST1602A(C) is equipped with CST16S2 and integrating input/output ports,Audio PWM, Timer and Low Voltage Reset...etc. on a chip.
Furthermore, CST1602A(C) extend its external device connection capability such as Serial ROM/Flash. The internal memory capacity includes 128Kx16 program/data FLASH plus 3Kx16 working SRAM.
