CEC1302D-C0-SZ

Overview

The CEC1302D-C0-SZ is a low-power crypto embedded controller featuring an ARM Cortex-M4 processor core with hardware floating-point support. It integrates 128 KB of SRAM and 32 KB of boot ROM within a 144-pin WFBGA package. The device includes dedicated cryptographic engines for AES, SHA-1/SHA-256, RSA, and ECC algorithms, alongside a true random number generator. Peripheral interfaces include four I2C/SMBus controllers, two SPI memory interfaces, five ADC channels, RTC, PWM outputs, and fan tachometer inputs.

Feature Summary

• Hardware-accelerated cryptographic processing supporting AES, SHA, RSA, and ECC algorithms with DMA interface
• Secure boot functionality utilizing digital signature validation via PKCS #1 with RSA-2048 encryption and SHA-256 hashing
• Integrated real-time clock with calendar registers, programmable alarms, and battery-backed resources
• RPM-based fan speed control algorithm with automatic tachometer feedback and aging detection

Applications

• System power management in laptop and desktop platforms
• Embedded controller applications requiring hardware root of trust
• Fan speed control and thermal management subsystems
• Low-power IoT devices requiring secure communication

Procurement Notes

Verify the specific suffix 'C0' against the manufacturer's current documentation to confirm pinout compatibility and feature set variations. Ensure design-in requirements align with the 144-pin WFBGA package outline and voltage specifications. Confirm that the intended application environment falls within the specified operating temperature range and humidity sensitivity levels defined in the electrical characteristics section.

Selection Notes

Select this component when system security requires a hardware root of trust and encrypted code execution from external SPI flash. It is suitable for designs needing integrated power management logic, RTC capabilities, and multiple I2C interfaces without external bridge chips. Consider the 144-pin package density and available GPIO multiplexing options for complex peripheral integration.

Part Context

This part belongs to the CEC1302 family of low-power crypto embedded controllers manufactured by Microchip Technology. These devices are designed to replace traditional Super I/O and EC combinations by integrating security features directly into the microcontroller architecture. The series supports various packaging options and is optimized for mobile computing and industrial control applications.

Replacement Considerations

Consult official substitution lists for compatible parts within the CEC1302 family. Verify pin-to-pin compatibility if replacing with variants having different suffixes. Ensure software migration strategies account for any silicon revisions or errata associated with alternative part numbers.
