DESCRIPTIONS
The S1C33240 is a CMOS 32-bit microcomputer composed of a CMOS 32-bit RISC core, Flash∗, RAM, DMA, timers, SIO,
PLL and other circuits. The S1C33240 can be operated with high speed and spend little current. With the ADC, PWM and the
MAC function, the S1C33240 is suitable for voice applications, PDAs and OA products such as printers.
