CEC1712H-S2-I/SX

Application Specific Microcontrollers Overview

The Microchip CEC1712H-S2-I/SX is a cryptographic embedded controller based on the ARM Cortex-M4 processor. It operates at 3.3 V and 1.8 V with an operating temperature range of -40 °C to +85 °C. The device features a 48 MHz clock, 256 KB SRAM (224 KB code/32 KB data), and 64 bytes of battery-backed storage. Security includes hardware accelerators for AES-256, SHA-384, ECDSA P-384, RSA up to 4096 bits, and a True Random Number Generator. It supports secure boot from external SPI Flash with key revocation and rollback protection.

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'S2' against the official datasheet inventory table to confirm package type and temperature grade. Ensure compatibility with the required 84-pin WFBGA footprint. Confirm that the -I designation matches the industrial temperature range specifications.

Application Specific Microcontrollers Selection Notes

Select this component when hardware-based cryptographic acceleration is required for secure boot or data integrity. The dual voltage support (1.8V/3.3V) allows integration with both legacy and modern platform controller hubs. Consider the 256 KB SRAM allocation if large firmware images are used.

Application Specific Microcontrollers Part Context

The CEC1712 belongs to Microchip's Cryptographic Embedded Controller family, designed specifically for high-security applications. It integrates a standard ARM Cortex-M4 core with specialized hardware engines to offload cryptographic tasks, reducing CPU load and improving performance compared to software-only solutions.

Application Specific Microcontrollers Replacement Considerations

Check for direct pin-compatible alternatives within the CEC171x series. Verify if the CEC1702 offers sufficient security features for the application, noting differences in memory size and peripheral availability.
