AVR - Trusted Platform Module (TPM) Microcontroller IC EEPROM 32-VFQFN Exposed Pad
Active286 in stock

Overview

The AT97SC3205T is a fully integrated Trusted Platform Module (TPM) based on an 8-bit AVR RISC core. It is a turnkey security solution designed to provide hardware-based encryption, secure key storage, and platform integrity measurement. The device is compliant with the TCG TPM Version 1.2 specification and features a dedicated hardware asymmetric crypto engine.

Why Choose This Part

This module is FIPS-140-2 certified, ensuring it meets rigorous security standards for RNG, HMAC, AES, SHA, and RSA operations. It simplifies security implementation by providing 2066 bytes of user-defined non-volatile storage and a standard I2C interface for communication with a host processor.

Applications

Embedded System Integrity
Used to perform secure boot and ensure that firmware has not been tampered with by measuring system software against known-good hashes.
Secure Key Storage
Utilizes internal EEPROM for the safe storage of RSA keys and user-defined data, preventing unauthorized extraction of sensitive credentials.
Network Authentication
Acts as a root of trust for securing network connections via SSL/TLS certificates and hardware-backed device identity.
