Overview

The AT97SC3204T-X2A1B-10 is a Microchip CryptoController based on the 8-bit AVR RISC architecture, specifically designed to function as a Trusted Platform Module (TPM). It is fully compliant with the TCG TPM version 1.2 and TCG PC client-specific TIS version 1.2 specifications. The device includes a hardware asymmetric crypto engine, a FIPS 140-2 compliant random number generator, and 1756 bytes of user-defined NV storage.

Why Choose This Part

This turnkey solution simplifies security implementation with its integrated AVR core and dedicated hardware crypto engine. It features internal EEPROM for secure key storage and a high-quality RNG, eliminating the need for external security components while maintaining TCG 1.2 compliance.

Applications

PC Client Security
Provides secure storage for RSA keys and platform integrity measurements in desktop and laptop computers.
Embedded System Trust
Acts as a root of trust for embedded industrial controllers requiring TCG-compliant security features.
Secure Boot and Attestation
Facilitates secure boot sequences and remote attestation by managing cryptographic identity and platform state.
