Analog Devices Inc./Maxim Integrated

The MAXQ1065 is a security coprocessor that 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.The MAXQ1065's low power consumption makes it suitable for battery-powered applications, and the extremely reduced footprint and pin count allow easy integration into medical and wearable devices. Its lifetime and operating range make it compatible with long-term deployments in harsh environments. The MAXQ1065 life cycle management allows flexible access control rules during the major life cycle stages of the device. Secure key loading protocol and secure factory preprogramming are available.DeepCover®embedded security solutions cloak sensitive data under multiple layers of advanced security to provide the most secure key storage possible. To protect against device-level security attacks, invasive and noninvasive countermeasures are implemented including active die shield, encrypted storage of keys using the ChipDNA PUF technology, and externally callable algorithmic subroutines.ApplicationsAnti-cloning, Anti-counterfeiting, Feature and Usage ControlCertificate ManagementMutual AuthenticationSecure Boot, Secure Firmware UpdateSecure Communication: Key Exchange, TLSSecure Data StorageSystem-Level Tamper Protection and Integrity
