The Microchip Trust Anchor (TA100) is a secure element from our portfolio of CryptoAutomotive™ security ICs for automotive security applications. It provides support for code authentication (aka secure boot), message authentication via MAC generation, support for trusted firmware updates, Qi 1.3 and Qi 2.0 wireless charging authentication, multiple key management protocols including TLS and other root-of-trust based operations. It is typically a companion device to a microcontroller (MCU) or microprocessor (MPU) on the same board.

The TA100 integrates multiple asymmetric, symmetric, and hashing security protocols supporting an ultra-secure method for key agreement, sign-verify authentication for automotive in-vehicle networking applications. Similar to all of our CryptoAutomotive™ security ICs, the new TA100 employs ultra-secure hardware-based cryptographic key storage and cryptographic countermeasures to eliminate potential backdoors linked to software weaknesses.

The device is agnostic of any microprocessor (MPU) or microcontroller (MCU) and compatible with our AVR® or ARM® processor based MCUs and MPUs. 

Download the Trust Platform Design Suite and request the TA100 custom configurator from your local sales representative to implement your use cases and leverage our secure key provisioning service.
