■ DESCRIPTION
The S1C33221/222 is a CMOS 32-bit microcomputer composed of a CMOS 32-bit RISC core, ROM, RAM,
DMA, timers, SIO, PLL and other circuits. The S1C33221/222 can be operated with high speed and spend little
current. With the ADC, PWM and the MAC function, the S1C33221/222 is suitable for voice applications, PDAs
and OA products such as printers.
