MAXQ1065GTC+

MAXQ1065GTC+ is an ultra-low-power cryptographic controller with ChipDNA™ for embedded devices. This security coprocessor provides turnkey cryptographic functions for root-of-trust, mutual authentication, data confidentiality and integrity, secure boot, secure firmware update, and secure communications with generic key exchange and bulk encryption or complete TLS support. The device integrates 8KB of secure storage for user data, keys, certificates, and counters with user-defined access control and life cycle management. It also has a configurable output pin and a tamper input pin. Commands are accessible through a standard SPI interface. It is used in applications such as secure communication: key exchange, TLS, secure data storage, mutual authentication, certificate management, anti-cloning, anti-counterfeiting, feature and usage control, system-level tamper protection and integrity, secure boot, and secure firmware update.
