CEC1736-S0-I/2HW-PROTO

Application Specific Microcontrollers Overview

The CEC1736-S0-I/2HW-PROTO is a prototype variant of the CEC173x Trust Shield family, functioning as a Real Time Platform Root of Trust Controller. It features a 96 MHz ARM Cortex-M4F core and supports up to two Application Processors via a single QSPI port in its 64-pin VFBGA (5.5x5.5x0.92 mm) package. Pre-provisioned with Soteria-G3 firmware, it implements NIST 800-193 and OCP security requirements, including hardware CNSA-based secure boot, SPI flash monitoring, and key management. The device provides immutable secure bootloading, runtime authentication, and crisis recovery capabilities for server and telecom applications.

Application Specific Microcontrollers Feature Summary

• Hardware CNSA Secure Boot with P-384, AES256, SHA-384, and ECDSA support
• Soteria-G3 Firmware compliant with NIST 800-193 and Open Compute Project standards
• Integrated SPI Flash Monitor for real-time integrity verification and intervention
• Physical Unclonable Function (PUF) and True Random Number Generator (SP800-90B)

Application Specific Microcontrollers Applications

• Server platforms requiring external root of trust
• Telecommunications infrastructure
• Industrial embedded computing systems

Application Specific Microcontrollers Procurement Notes

This part number identifies a proto device intended for evaluation and development purposes. Verify that the specific ordering suffix corresponds to the TrustCUSTOM or TrustFLEX configuration required for your prototyping phase. Confirm package availability and revision status through official Microchip channels prior to integration planning.

Application Specific Microcontrollers Selection Notes

Select this model when evaluating the 64-pin VFBGA package variant which supports one QSPI port for a single Application Processor. Ensure compatibility with the 84-pin socket evaluation kit if migrating to higher I/O configurations later. Validate that the pre-provisioned Soteria-G3 firmware meets the specific security policy requirements for the target system architecture.

Application Specific Microcontrollers Part Context

The CEC1736-S0-I/2HW-PROTO belongs to the CEC173x-TFLX Trust Shield Family. It is distinct from the 84-pin 2ZW package variant by offering a reduced pin count suitable for simpler host configurations. As a proto device, it facilitates rapid integration of platform resilience features before final production silicon selection.

Application Specific Microcontrollers Replacement Considerations

For production volumes, consider the non-proto variants such as CEC1736-SO-I/2HW-TFLX or CEC1736-SO-I/2HW-TCSM. These production parts maintain the same 64-pin footprint and functional specifications but are optimized for manufacturing rather than development flexibility.
