About this manual

The CK802 is a low‑cost, ultra‑low‑power 32‑bit embedded CPU core developed by C‑SKY Microsystems. It targets smart‑card, smart‑grid, low‑cost micro‑controller and wireless sensor network applications and implements a mixed 16/32‑bit RISC instruction set.

The manual covers the processor's micro‑architecture, programming model, data formats, full register set, 32‑bit and 16‑bit instruction encodings, pipeline operation, exception handling, work‑mode switching, and provides appendices with MPU configuration examples and an instruction glossary. This manual is written in Chinese.
