CEC1736-S0-I/2HW-TCSM

Application Specific Microcontrollers Overview

The Microchip CEC1736-S0-I/2HW is a Real Time Platform Root of Trust Controller featuring an ARM Cortex-M4F processor running at 96 MHz. It operates on a 3.3 V supply with interface voltages supporting 3.3 V and optional 1.8 V SPI. The device includes 384 KB SRAM, 8 Kbit OTP memory, and 2 MByte integrated SPI Flash. Security features include CNSA-compliant secure boot, AES-256 encryption, SHA-384 hashing, and hardware PUF. It utilizes a 64-pin VFBGA package with single SPI channel monitoring capabilities.

Application Specific Microcontrollers Feature Summary

• ARM Cortex-M4F core with 96 MHz clock and floating-point support
• CNSA compliant secure boot loader with AES-256 and SHA-384 support
• Integrated 2 MByte SPI Flash for the 64-pin variant
• Hardware accelerators for RSA, ECC, and Deterministic Random Number Generator

Application Specific Microcontrollers Applications

• Server platform root of trust
• Telecommunications infrastructure
• Industrial embedded computing

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range. Ensure compatibility with the target host processor voltage levels (1.8V or 3.3V) before integration. Confirm that the single SPI monitor configuration meets the system's security architecture requirements.

Application Specific Microcontrollers Selection Notes

Select this model for applications requiring a single SPI flash monitor channel. Compare against the 84-pin CEC1736-S0-I/2ZW if dual-channel monitoring for both BMC and CPU is required. Consider the 64-pin form factor constraints when designing the PCB layout for the VFBGA package.

Application Specific Microcontrollers Part Context

This component belongs to the CEC173x Trust Shield Family, designed as a Real Time Platform Root of Trust Controller. It serves as a configurable mixed-signal advanced I/O controller intended to secure server, telecom, and industrial platforms against firmware tampering and unauthorized access.

Application Specific Microcontrollers Replacement Considerations

The CEC1734-S0-I/2HW is a pin-compatible alternative within the same family but lacks the specific device ID and potentially different internal configuration associated with the CEC1736 series. Verify functional equivalence in secure boot and crypto acceleration features.
