CEC1736-S0-I/2ZW

Application Specific Microcontrollers Overview

The CEC1736-S0-I/2ZW is a TrustFLEX platform trust root controller within the CEC173x series, designed for external root of trust (eRoT) implementations. It features an ARM Cortex-M4 core operating at up to 48 MHz with 96 kB program memory and 32 kB data RAM. The device integrates hardware security functions including secure boot, secure update, crisis recovery, verification, SPI monitoring, and ownership transfer. Packaged in a WFBGA-144 format, it supports I2C, SPI, and UART interfaces and operates within a commercial temperature range of 0°C to +70°C.

Application Specific Microcontrollers Feature Summary

• Integrated NIST and OCP recommended security features: secure boot, secure update, crisis recovery, verification, SPI monitoring, and ownership transfer.
• ARM Cortex-M4 processor core with 96 kB program memory and 32 kB SRAM.
• Supports configuration via the TPDS (Trust Platform Design Suite) tool for rapid prototyping.
• Available in WFBGA-144 package with 116 I/O pins.

Application Specific Microcontrollers Applications

• Data center platforms requiring external root of trust.
• Telecom and 5G infrastructure systems.
• Industrial IoT embedded computing applications.

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm the exact variant, as suffixes define packaging, temperature grade, and security customization levels. Ensure compatibility with the EV42J24A evaluation kit if development tools are required. Confirm moisture sensitivity handling procedures during storage and assembly.

Application Specific Microcontrollers Selection Notes

Select this component when an external root of trust is required for server or telecom hardware. Compare with the CEC1734 model if pin count or memory requirements differ. Utilize the TPDS configurator tool to define specific security policies before ordering. Ensure the host system supports the necessary SPI flash interface for secure boot operations.

Application Specific Microcontrollers Part Context

This part belongs to the CEC173x family of platform trust root controllers. It is distinct from general-purpose microcontrollers like the CEC1302D due to its specialized focus on hardware-based security and identity management. The device is often evaluated using the EV42J24A kit alongside proto devices.
