S1C33S01
32-bit Single Chip Microcomputer
● High-speed 32-bit RISC Core
● Multiply Accumulation
● 8K-byte RAM Built-in
● 2-ch. SIO
■ DESCRIPTION
The S1C33S01 consists of the S1C33000 32-bit RISC type CPU as the core, a bus control unit, an interrupt
controller, timers, serial interface circuits, 8K-byte RAM and other circuits. It also includes a high-speed oscilla-
tion circuit, PLL and low-speed oscillation circuit allowing high-speed operation and low-power operation with
excellent clock functions. The S1C33S01 also provides a DSP function, by using the internal MAC (multiplica-
tion and accumulation) operation function, it makes it possible to design simply voice synthesis systems.
