CEC1702Q-S1-I/SX

Application Specific Microcontrollers Overview

The CEC1702Q-S1-I/SX is a cryptographic embedded controller from Microchip Technology, designed for IoT platforms. It features an ARM Cortex-M4F processor core with hardware floating-point support and operates on 3.3V or 1.8V supply planes. The device integrates 480KB of SRAM (split into two blocks) and 64KB of Boot ROM. Key security features include a hardware root of trust, secure boot loader, AES engine supporting 128/192/256-bit keys, SHA hashing, and public key cryptography for RSA up to 4096 bits and ECC up to 640 bits. It includes four I2C controllers, UARTs, SPI interfaces, and various timers.

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'Q-S1-I/SX' against the official datasheet inventory table to confirm availability and exact feature mapping. Check for any End-of-Life (EOL) notifications or production discontinuance notices from Microchip Technology prior to procurement planning.

Application Specific Microcontrollers Selection Notes

Select this component when hardware-based cryptographic acceleration is required for IoT security. Ensure the design supports the 84-pin WFBGA package and provides separate VBAT and VTR power planes. Verify that the external SPI Flash memory is compatible with the Boot ROM's loading requirements for secure image authentication.

Application Specific Microcontrollers Part Context

The CEC1702 family is part of Microchip's specialized embedded controller line, focusing on security for connected devices. It differs from standard microcontrollers by integrating dedicated cryptographic hardware and a secure boot mechanism directly into the silicon architecture.

Application Specific Microcontrollers Replacement Considerations

No direct public substitute part numbers are listed in the provided documentation. Evaluate other Microchip MEC or CEC series devices based on pin compatibility and cryptographic feature requirements.
