CEC1736-S0-I/2ZW-TCSM

Application Specific Microcontrollers Overview

The CEC1736-S0-I/2ZW-TCSM is a Real Time Platform Root of Trust Controller in an 84-pin WFBGA package. It features a 96 MHz ARM Cortex-M4F processor, 384 KB SRAM, and 4 MB internal SPI Flash. Operating at 3.3 V with optional 1.8 V SPI, it supports -40°C to 85°C. Security includes CNSA-compliant Secure Boot, AES-256 encryption, SHA-384 hashing, PUF, and TCG DICE compliance. Dual SPI monitors provide real-time flash integrity verification.

Application Specific Microcontrollers Feature Summary

• ARM Cortex-M4F processor running up to 96 MHz with floating-point support
• Dual SPI channel monitoring with active intervention for firmware integrity
• Hardware crypto accelerators for AES-256, RSA, ECC, and SHA-2 families
• 4 MB internal SPI Flash and 384 KB SRAM (320 KB code / 64 KB data)

Application Specific Microcontrollers Applications

• Server platform root of trust controllers
• Telecommunications infrastructure security
• Industrial IoT embedded computing

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'TCSM' against Microchip documentation to confirm sample or custom configuration status. Ensure the 84-pin WFBGA footprint matches the target PCB design. Confirm that the operating voltage requirements align with the system's 3.3 V and 1.8 V rails.

Application Specific Microcontrollers Selection Notes

Select this model over the 64-pin variant if dual host processor support and independent SPI flash monitoring are required. The 84-pin package provides separate I/O regions for BMC and CPU interfaces. Verify that the application utilizes the full 4 MB internal flash capacity or requires the additional GPIO count available in the 84-pin configuration.

Application Specific Microcontrollers Part Context

This component belongs to the CEC173x Trust Shield Family, designed as a hardware root of trust for servers and networking equipment. It integrates immutable boot ROM and mutable firmware execution environments to enforce secure boot sequences and runtime integrity checks across multiple host processors.

Application Specific Microcontrollers Replacement Considerations

The CEC1734-S0-I/2ZW-TCSM is a compatible alternative within the same family but offers only 2 MB of internal flash and single-channel SPI monitoring. Verify if the reduced memory and single-host monitoring capabilities meet the system requirements before substitution.
