CEC1734-S0-I/2HW-TCSM

Application Specific Microcontrollers Overview

The CEC1734-S0-I/2HW is a Real Time Platform Root of Trust Controller in the CEC173x family, designed for servers and embedded computing. It features an ARM Cortex-M4F processor running up to 96 MHz with floating-point support. The device includes 384 KB SRAM (320 KB code, 64 KB data) and 8 Kbit OTP memory. Operating at 3.3 V with an industrial temperature range of -40°C to 85°C, it integrates a single SPI Flash monitor for firmware integrity verification. Security features include CNSA-compliant secure boot, hardware accelerators for AES-256 and SHA-384, and a Physically Unclonable Function (PUF).

Application Specific Microcontrollers Feature Summary

• ARM Cortex-M4F processor core operating at programmable frequencies up to 96 MHz.
• Single SPI Flash Monitor block providing real-time load module verification and intervention.
• Hardware crypto engine supporting AES-256, SHA-2 (256/384/512), RSA, and ECC algorithms.
• Integrated 2 MByte in-package SPI Serial Flash storage.

Application Specific Microcontrollers Applications

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

Application Specific Microcontrollers Procurement Notes

Verify the package marking and date code against the specific revision indicated by the suffix. Confirm that the single-channel SPI monitor configuration aligns with the system's host architecture requirements. Ensure compatibility with the required voltage levels for the connected SPI flash devices.

Application Specific Microcontrollers Selection Notes

Select this model over the 84-pin variant when only one SPI channel requires monitoring or isolation. The 64-pin WFBGA package offers fewer GPIO pins compared to the 84-pin version. Verify that the 2 MByte integrated flash capacity meets the firmware storage needs without requiring external memory expansion.

Application Specific Microcontrollers Part Context

This component belongs to the Microchip CEC173x Trust Shield Family, which serves as a Real Time Platform Root of Trust. The CEC1734 designation indicates the 64-pin package variant with a single SPI monitor, distinguishing it from the CEC1736 which supports dual monitors in an 84-pin package.

Application Specific Microcontrollers Replacement Considerations

Direct pin-compatible replacements within the same family include the CEC1736-S0-I/2HW, which provides dual SPI monitors but requires an 84-pin footprint. No other direct substitutes are documented in the provided datasheet.
