ATECC608B-TFLXACTS

Specialized ICS Overview

The ATECC608B-TFLXACTS is a hardware security component from Microchip Technology’s CryptoAuthentication™ series, designed for secure key storage and cryptographic operations. It integrates an ECC P-256 engine, SHA-256 hash function, AES-128 encryption, and a True Random Number Generator (TRNG). The device features 16KB of structured EEPROM for secure data management and communicates via I²C or Single Wire Interface (SWI). Packaged in an 8-SOIC case with Tape & Reel (TR) delivery, it operates within a voltage range of 2V to 5.5V and supports surface-mount installation.

Specialized ICS Feature Summary

• Hardware-based ECC P-256, SHA-256, and AES-128 engines
• 16KB structured EEPROM with access control
• Supports I²C (up to 1MHz) and SWI interfaces
• Integrated True Random Number Generator (TRNG)

Specialized ICS Applications

• IoT device authentication and identity management
• TLS/DTLS handshake acceleration
• Secure boot and firmware update verification

Specialized ICS Procurement Notes

Verify the specific ordering suffix 'TFLXACTS' against official Microchip documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing I²C bus configurations and voltage levels during integration planning.

Specialized ICS Selection Notes

Select this component when hardware-level isolation of cryptographic keys is required. It is suitable for applications needing certified random number generation and support for standard elliptic curve algorithms without exposing private keys to the main processor.

Specialized ICS Part Context

This part belongs to the ATECC608x family of Secure Elements. It shares core cryptographic capabilities with variants like the ATECC608A and ATECC608C but differs in interface options and package availability. The TFLXACTS designation indicates a specific manufacturing configuration within the broader CryptoAuthentication portfolio.

Specialized ICS Replacement Considerations

Direct pin-to-pin replacements include other ATECC608B variants such as ATECC608B-TNGACTS or ATECC608B-MAHDA-S, provided the interface and package requirements match.
