Overview

CEC1702 is a full-featured 32-bit Arm® Cortex®-M4-based microcontroller (MCU) that enables secure boot of system firmware, providing an immutable identity and a root of trust to ensure that the firmware is untouched and hasn’t been corrupted. These devices can be used as stand-alone MCUs, while also providing easy-to-use firmware authentication, public key and customer-specific pre-provisioning flexibility to minimize your risk.

MA990003 CEC1702Q-S1 PIM is designed to work with the DM990013 CEC1x02 evaluation and development board. The CEC1702Q-S1 Plug-In-Module (PIM) enables customers to evaluate, develop and program all aspects of the CEC1702, including the OTP.

MA990003 is designed to work with the CEC1702Q-S1 silicon which supports Microchip's Soteria custom firmware to speed adoption and implementation of a secure pre-boot platform. Soteria is highly configurable custom firmware that runs on CEC17x2 devices to provide a complete platform to establish a chain of trust for platform firmware resiliency. Soteria-G1 runs on the CEC1702Q-S1 and Soteria-G2 runs on the CEC1712Q-S2. The Soteria solution is designed to work with virtually any application processor that meets two criteria: the application processor can be held in reset, and the application processor loads its first code from SPI-Flash.

Soteria is available to CEC1702Q-S1 customers under a Signed License Agreement (SLA).
