The Microchip Trust Anchor (TA101) is a secure authentication IC from our portfolio of CryptoAutomotive™ and CryptoAuthentication security ICs for automotive and industrial security applications. It provides support for 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 for user access privileges and network authentication such as TLS and other root-of-trust based operations. It is a companion device to any microcontroller (MCU) or microprocessor (MPU) on the same board.

The TA101 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. It enhances the cryptographic security strength from 128bits to 256 bits.

Similar to all of our CryptoAutomotive™ security ICs, the new TA101 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 TA101 custom configurator from your local sales representative to implement your use cases and leverage our secure key provisioning service.
