Description

The S3CK225/FK225 single-chip CMOS microcontroller is designed for high performance using Samsung's new 8-bit CPU core, CalmRISC.

CalmRISC is an 8-bit low power RISC microcontroller. S3CK225's basic architecture follows Harvard style, that is, S3CK225 has separate program memory and data memory. Both instruction and data can be fetched simultaneously without causing a stall, using separate paths for memory access. Represented below is the top block diagram of the CalmRISC microcontroller.
