CEC1736-S0-I/2HW-TFLX

Application Specific Microcontrollers Overview

The CEC1736-S0-I/2HW-TFLX is a Real Time Platform Root of Trust Controller from the CEC173x Trust Shield Family, designed for servers, telecommunications, and industrial applications. It features a 32-bit 96 MHz ARM Cortex-M4F processor core with closely coupled memory. The device supports NIST 800-193 and Open Compute Project (OCP) security requirements. Hardware security includes CNSA-based secure boot (P-384), AES256, SHA-384, ECDSA, and a True Random Number Generator compliant with SP800-90B. It utilizes Soteria-G3 firmware for secure boot, attestation, and crisis recovery. The component is available in an 84-pin WFBGA package.

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against the official Microchip Product Identification System to confirm package type and temperature range. Ensure compatibility with the required SPI flash monitoring voltage configuration (1.8V or 3.3V). Confirm that the selected variant matches the intended system architecture, particularly regarding the number of supported Application Processors and QSPI ports.

Application Specific Microcontrollers Selection Notes

Select the CEC1736-S0-I/2HW-TFLX when a single QSPI port is sufficient for one Application Processor with up to two SPI flash components. The 64-pin 2HW package offers a smaller footprint compared to the 84-pin 2ZW variant. Consider the internal flash capacity options (2MB or 4MB) based on the size of the Soteria-G3 images and customer certificate chains required for the specific deployment.

Application Specific Microcontrollers Part Context

This component belongs to the CEC173x Trust Shield family of Real Time Platform Root of Trust Controllers. It is a partially configured and provisioned variant pre-loaded with Soteria-G3 firmware. The device is designed to minimize development time while supporting unique credentials for Application Processor images, enabling rapid prototyping and integration into platform root-of-trust architectures.

Application Specific Microcontrollers Replacement Considerations

The CEC1736-S0-I/2HW-TFLX is part of the CEC173x series. For systems requiring support for two Application Processors with dual QSPI ports, the 84-pin package variants such as CEC1736-S0-I/2ZW-TFLX are the appropriate alternative within the same family.
