TA100 (B5)

Description

The Microchip Technology Inc. Trust Anchor security device TA100 is intended for automotive, industrial, or

commercial systems and can provide support for code authentication (secure boot), Message Authentication Code

(MAC) generation, support for trusted firmware updates, multiple key management protocols including Transport

Layer Security (TLS), and other root-of-trust-based operations.

It is typically a companion device to an MCU or MPU on the same board.
