„ DESCRIPTIONS
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.
