A-China Semiconductor Limited

Each 32-bit MCU with its own natural created ID, use to protect your firmware and data, the ID is created during the silicon process, which is reliable, durable, and unpredictable for higher encryption key protection and confidential data exchange purposes. The idea is similar to the human fingerprint. The applications include authentication for IoT, smart locks, smart car keys, smart ID cards etc.
Powerful specification at a very low cost
