SHA104-TFLXAUTHR-CZ-HV

Overview

The SHA104-TFLXAUTHR-CZ-HV is a pre-provisioned CryptoAuthentication device from Microchip Technology, designed for symmetric authentication in disposable and accessory applications. It features hardware-protected symmetric key storage, a 384-byte user EEPROM, and a monotonic counter. The component supports I2C and Single-Wire Interface (SWI) protocols with a supply voltage range of 1.65V to 5.5V. It includes an internal NIST-compliant random number generator and physical protection mechanisms against invasive attacks.

Feature Summary

• Hardware-based symmetric security engine supporting MAC generation
• Protected memory for symmetric keys and user data
• Integrated high-quality random number generator
• Physical anti-tampering and anti-invasive attack measures

Applications

• Accessory and consumable authentication
• Ecosystem control and anti-counterfeiting
• One-time use device identification

Procurement Notes
