描述 Description

The full-featuredCEC1712 Arm® Cortex®-M4-based microcontroller providessecure boot with hardware root of trust protection in a pre-boot mode for thoseoperating systems booting from external SPI flash memory. In addition, theCEC1712 provides key revocation and code rollback protection during operatinglife, enabling in-field security updates. Complying with NIST 800-193 guidelines,the CEC1712 protects, detects and recovers from corruption for total systemplatform firmware resiliency. The secure boot with hardware root of trust iscritical in protecting the system against threats before they can load into thesystem and only allows the system to boot using software trusted by themanufacturer. The CEC1712 secure bootloader loads, decryptsand authenticates the firmware to run on the CEC1712 from the external SPIflash. The validated CEC1712 code subsequently authenticates the firmwarestored in SPI flash for the first application processor. Up to two applicationprocessors are supported with two flash components supported for each.  Inaddition to preventing malicious malware during pre-boot in 5G and data centeroperating systems, Microchip’s CEC1712 and Soteria-G2 combination is a securityenabler for connected autonomous vehicle operating systems, automotive AdvancedDriver Assisted Systems (ADAS) and other systems that boot out of external SPIflash.

CEC1712H-S2-I/SX works with Soteria-G2 firmware to provide secure boot with hardware root of trust protection in a pre-boot mode for operating systems booting from external SPI flash memory.  Together, this solution allows designers to speed adoption and implementation of a secure pre-boot and secure firmware update platform.  Soteria-G2 firmware simplifies risk reduction during code development by using the CEC1712 immutable secure bootloader, implemented in Read-Only Memory (ROM), as the system root of trust.
