■ DESCRIPTION

The S1C33209 is a CMOS 32-bit microcomputer composed of a CMOS 32-bit RISC core, 8K-byte RAM, 4-

channel SIO, A/D converter, timers, PLL and other circuits. The S1C33209 features high-speed operation and

low current consumption. It is suitable for various portable equipment and multimedia control systems. The

S1C33209 also provides a DSP function using the internal MAC (multiplication and accumulation) operation

function with the A/D converter, this makes it possible to achieve speech recognition and voice synthesis sys-

tems.
