CEC1734-S0-I/2ZW-TCSM

Application Specific Microcontrollers Overview

The CEC1734-S0-I/2ZW-TCSM is a Real Time Platform Root of Trust Controller from the Microchip CEC173x family, housed in an 84-pin WFBGA package. It features a 96 MHz ARM Cortex-M4F processor with floating-point support and 384 KB SRAM. The device integrates 4 MBytes of internal SPI Flash and dual SPI monitor blocks for firmware integrity verification. Security functions include hardware accelerators for AES-256, SHA-2, RSA, and ECC, alongside a Physically Unclonable Function (PUF) and Deterministic Random Number Generator (DRNG). Operating conditions specify 3.3 V supply voltage and a temperature range of -40°C to 85°C.

Application Specific Microcontrollers Feature Summary

• ARM Cortex-M4F processor running at up to 96 MHz with floating-point unit
• Dual SPI Flash Monitor blocks with active intervention capabilities
• Integrated 4 MByte SPI Flash and 384 KB SRAM
• Hardware security accelerators supporting AES, SHA-2, RSA, and ECC

Application Specific Microcontrollers Applications

• Server platform root of trust controllers
• Telecommunications infrastructure security
• Networking equipment authentication
• Industrial embedded computing security

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix '-TCSM' against official Microchip documentation to confirm it denotes the TrustCUSTOM variant rather than standard production units. Ensure the 84-pin WFBGA package type matches the design requirements for dual SPI channel monitoring. Confirm that the industrial temperature grade (-40°C to 85°C) aligns with the target system environment specifications.

Application Specific Microcontrollers Selection Notes

Select this model over the 64-pin variant when dual host processor support or independent SPI flash monitoring for both BMC and CPU is required. The 84-pin package provides separate I/O regions for two distinct voltage domains (1.8V or 3.3V). Verify that the 4 MByte internal flash capacity meets the firmware storage needs without requiring external memory components.

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 secure boot loader and firmware integrity monitor for high-security environments. The device supports TCG DICE compliance and SPDM for attestation, ensuring immutable code execution and secure key management within the platform architecture.

Application Specific Microcontrollers Replacement Considerations

The CEC1736-S0-I/2ZW-TCSM is the primary alternative within the same package, offering identical security features but potentially different main/sub IDs. Cross-referencing the specific silicon revision and life cycle stage settings is necessary when substituting between CEC1734 and CEC1736 variants.
