Microchip Technology has introduced TrustAnchor100 (TA100) CryptoAutomotive security IC that supports in-vehicle network security solutions such as secure boot, firmware update, and message authentication, including Controller Area Network (CAN) MAC at bus speed.


TA100 provides an alternative in-vehicle network architecture implementation for secure boot and message authentication, hence the OEMs and their module suppliers don’t need to rearchitect their application software. The IC has already been approved by multiple OEMs around the world as a solution for EVITA Medium and EVITA Full HSM requirements.


The device offers pre-programmed cryptographic internal application code provisioned with unique asymmetric key-pairs and associated x.509 certificates. This reduces the challenges associated with secure code development eventually reducing risk, cost, and time to market. TA100 is AEC-Q100 Automotive Grade-1 qualified, FIPS 140-2 CMVP Security Level 2 rated and Physical Key Protection Level 3 certified, and has achieved the highest possible vulnerability assessment rating of Joint Interpretation Library (JIL) High.


It offers multiple software components like AUTOSAR drivers, MCALs, and Microchip’s CryptoAuthentication library for the integration of the device into an industry-standard operating system or AUTOSAR software stack. The TA100 is available in 8- and 14-pin SOIC packages starting at $1.50 in 10,000-unit quantities.


Features of TA100 CryptoAutomotive Security IC

  • Significant cost and time savings compared to redesigning with a new MCU
  • Minimal MCU code updates resulting in little to no impact to existing host MCU functional safety ratings
  • Pre-programmed with built-in security measures to eliminate the need for in-house security expertise
  • Elimination of risk associated with significant MCU code updates
  • More whole-chip tampers with a higher level of certifiability
  • True hardware key isolation
