Available as a CryptoAuthentication™ or CryptoAutomotive™ Secure IC, the new TA101 device focuses on larger key sizes and enhanced cybersecurity requirements

Microchip Technology has launched its latest TrustAnchor Security IC, the TA101, which can accommodate complex automotive and embedded security use cases. The TA101 supports large key sizes up to ECC P521, SHA512, RSA-4K and AES256 with greater security strength, exceeding current standards and allowing room for future adjustments while maintaining backwards compatibility for smaller keys. The TA101 is offered as an industrial-grade CryptoAuthentication™ Security IC and as a CryptoAutomotive™ Security IC supporting AEC-Q100 Grade 1 qualified devices.

As the latest device in Microchip’s portfolio of security ICs, the TA101 is specifically designed to support automotive security, data center and industrial applications. The cryptographic companion device works alongside a microcontroller (MCU) or microprocessor (MPU) to handle cryptographic functions including public key infrastructure, certificate management and secure key storage requirements. The TA101 offers easy patch updates, message authentication, Transport Layer Security (TLS), secure boot, High-bandwidth Digital Content Protection (HDCP), firmware updates, security upgrades, transfer of ownership, key management and WPC Qi® 1.3 authentication.

“It is critically important for OEMs to not only comply with current standards but to stay a step ahead when it comes to security. By introducing key sizes associated with 256 bits of security strength, the TA101 offers great key strength diversity now and for future applications,” said Nuri Dagdeviren, corporate vice president of Microchip’s Secure Computing Group. “Additionally, Microchip’s modular security solution approach allows customers to choose an optimally sized and priced MCU based on the focus application of the module, while standardizing a single security solution that satisfies virtually all security requirements.”

The TA101 delivers an alternative architecture to on-die multicore MCU/MPU management of in-vehicle networking by offering an off-chip component to handle secure boot and message authentication.  The device is compatible with a wide range of MCUs or MPUs, enabling flexible solutions that can help lower costs and reduce time to market.
