■ DESCRIPTION
The S1C33L03 is a CMOS 32-bit microcomputer composed of a CMOS 32-bit RISC core, RAM, DMA, timers,
SIO, PLL, LCD controller, SDRAM controller and other circuits. The S1C33L03 can be operated with high speed
and spend little current. With the ADC, PWM and the MAC function, the S1C33L03 is suitable for voice applica-
tions and PDAs.
