ECC608-TFLXWPCU-PROTO

Specialized ICS Overview

The ECC608A-MAH1Z-S is a pre-provisioned security IC from Microchip Technology, belonging to the CryptoAuthentication family. It is designed for hardware-based authentication and secure key storage in IoT applications. The device features an I2C interface with a configurable address and supports P-256 Elliptic Curve Cryptography (ECC) for digital signatures and key exchange. It includes a hardware True Random Number Generator (TRNG) compliant with NIST SP 800-90 standards. The chip provides 16 flexible key slots with customizable access policies, ensuring private keys never leave the secure element. It operates within a voltage range of 2V to 5.5V and is available in compact packages such as 8-UDFN.

Specialized ICS Feature Summary

• Pre-provisioned with fixed configuration for simplified integration
• Supports WPC Qi 1.3 authentication and TLS 1.2/1.3 connections
• Includes dedicated slots for WPC Manufacturing CA and Product Unit Certificates
• Features I/O protection key slot to secure I2C communication

Specialized ICS Applications

• WPC Qi 1.3 Wireless Power Transmitter Authentication
• Secure IoT TLS Connections for Cloud Services
• Secure Boot and Secure Firmware Update Systems

Specialized ICS Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature range. Ensure the pre-provisioned configuration matches the target application requirements, as the Configuration Zone is locked after manufacturing. Confirm I2C address compatibility with the host system, noting that it may differ from generic ATECC608 variants.

Specialized ICS Selection Notes

Select this variant when WPC Qi 1.3 compliance or specific TLS provisioning is required out-of-the-box. It is suitable for devices needing immediate authentication capabilities without custom provisioning steps. Compare with generic ATECC608 models if flexible, user-defined slot configurations are necessary instead of fixed factory settings.

Specialized ICS Part Context

This component is part of the Microchip TrustFLEX secure element family, specifically tailored for the Wireless Power Consortium ecosystem. It serves as a specialized version of the ATECC608 series, optimized for power transmitter authentication. The device integrates seamlessly with Microchip's Trust Platform Design Suite for development and management.

Specialized ICS Replacement Considerations

Generic ATECC608 devices require manual provisioning and do not natively support WPC Qi 1.3 certificates. Substitutes must be verified for compatible pinouts and I2C addressing. No direct cross-model replacements with identical pre-provisioned content exist; alternative secure elements may require significant firmware and hardware redesign.
