CEC1736-S0-I/2ZW-PROTO2

Application Specific Microcontrollers Overview

The CEC1736-S0-I/2ZW-PROTO2 is an embedded controller from the CEC173x Trust Shield Family, designed as a Real Time Platform Root of Trust Controller. It features a 96 MHz ARM Cortex-M4F processor with floating-point support and 384 KB SRAM. The device integrates 4 MB internal SPI Flash and dual SPI monitor blocks for BMC and CPU channels. Operating at 3.3 V with optional 1.8 V interfaces across -40°C to 85°C, it provides hardware cryptographic accelerators including AES, SHA-2, RSA, and ECC. Security features include secure boot, PUF-based key generation, TCG DICE compliance, and tamper protection.

Application Specific Microcontrollers Feature Summary

• ARM Cortex-M4F processor running up to 96 MHz with FPU and MPU
• Dual SPI Monitor blocks with active intervention for BMC and CPU flash integrity
• Integrated 4 MB SPI Flash and 384 KB SRAM (320 KB code / 64 KB data)
• Hardware crypto engine supporting AES-256, SHA-2, RSA, and ECC algorithms

Application Specific Microcontrollers Applications

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

Application Specific Microcontrollers Procurement Notes

Verify that the specific suffix '-PROTO2' aligns with the intended development or prototype phase requirements. Confirm package compatibility with the 84-pin WFBGA footprint. Ensure design specifications match the 3.3 V operating voltage and -40°C to 85°C temperature range defined in the datasheet.

Application Specific Microcontrollers Selection Notes

Select this model over the 64-pin variant when dual host processor support (BMC and CPU) is required. The 84-pin package provides two independent SPI monitor blocks and 4 MB of integrated flash, compared to single-channel and 2 MB options in smaller packages. Verify GPIO count requirements against the 71 available pins in the 84-pin configuration.

Application Specific Microcontrollers Part Context

This component belongs to the CEC173x Trust Shield Family, which serves as a hardware root of trust for servers and networking equipment. The CEC1736 variant specifically targets applications requiring dual-host security monitoring, distinguishing it from the CEC1734 which supports only a single SPI channel.

Application Specific Microcontrollers Replacement Considerations

CEC1734-S0-I/2ZW-PROTO2 offers similar functionality but lacks the second SPI monitor block and has reduced integrated flash capacity. Cross-package replacements are not feasible due to pin count differences between the 64-pin and 84-pin variants.
