Microchip’s Trust Shield family provides a complete solution for protecting data centers, telecommunications and network systems against rapidly evolving security threats

India, May 18, 2022– As the market need for security develops, platforms also need to evolve rapidly to protect against cyber attacks during launch, real-time and system updates. With these new market threats, designers cannot accept that the equipment they use is reliable and must start looking for new technologies to protect their systems. Microchip Technology Inc. (Nasdaq: MCHP) today announced its fully configurable microcontroller-based CEC1736 Trust Shield family, which addresses this challenge by going beyond the firmware guidelines of the NIST 800-193 firmware firmware with runtime protection, which secures the secure boot process while establishes a whole chain of trust for the system platform.

The CEC1736 solution expands Microchip’s offer to provide cyber resilience to end equipment. It is a fully configurable real-time trust platform that allows runtime firmware protection in SPI Flash and I2C / SMBus filtering against runtime attacks. The attestation feature provides reliable evidence to ensure that critical devices in the platform are authentic. Lifecycle and transfer of ownership functions protect secrets throughout the lifecycle of the final product and during the transfer of ownership of the product, allowing different operators to use the system platform securely without compromising information.


“The presumption of equipment reliability is no longer acceptable and it is imperative that you both expect and protect yourself from unauthorized firmware components while not trusting peripheral components until they are proven to be trustworthy,” said Ian Harris. , Vice President of Microchip’s Computing Products Business Unit. “Our CEC1736 Trust Shield family provides a complete solution to these challenges, simplifying the development and provision of keys and other secrets, while speeding up time to market and providing the flexibility to face threats.”

The advanced hardware crypto encryption package of the CEC1736 Trust Shield family is equipped with AES-256, SHA-512, RSA-4096, ECC with a key size of up to 571 bits and an elliptic curve digital signature algorithm (ECDSA) with 384-bit length key. The 384-bit hardware physical non-cloned function (PUF) allows unique master key, symmetric secretion, private key generation and protection. The advanced trust and security solution, which complies with the NIST 800-193 and OCP security guidelines, allows the rapid adoption of the latest security achievements and standards.

The Microchip CEC1736 Trust Shield family includes silicon, software, tools, development board and security capabilities that manage the end-to-end platform firmware protection that customers need.

“Security is a matter of business continuity, consumer privacy and national security, so it is everyone’s responsibility to ensure that it is protected,” said Frederick Thomas, chief technology officer of Kudelski IoT, a leading IoT security expert. “Microchip has taken important steps to ensure that the CEC1736 Trust Shield family is robust against advanced attack methods, working with us to ensure that their hardware is independently evaluated in our state-of-the-art security labs. This should reassure Microchip customers that they are working with a secure, state-of-the-art microcontroller that contributes to the overall security of the connected world. “

Development tools

Microchip’s easy-to-use CEC1736 Trust Shield family development tools begin with the Trust Platform Design Suite (TPDS), a graphical user interface (GUI) configurator for exploring capabilities, defining security configurations, and providing prototyping secrets and production. Microchip’s MPLAB® Harmony, a fully integrated built-in software development framework, simplifies device setup, library selection and application development. Other support includes the CEC1736 development board.


The CEC1736 Trust Shield family is now available, including the CEC1736 96MHz Arm® Cortex®-M4-based microcontroller in an 84-pin WFBGA package. The family also includes Microchip’s proven Soteria-G3 firmware, the CEC1736 development board, and Microchip’s Trust Platform Design Suite (TPDS) for configuring, securing, and programming the part.

The development board is now available:

• Development board CEC1736 (EV19K07A – $ 399.00)
