AT97SC3204-X2A1A-10

Overview

The AT97SC3204-X2A1A-10 is a Trusted Platform Module (TPM) compliant with TCG TPM version 1.2 and TCG PC Client-specific TPM Interface Specification (TIS) version 1.2. It integrates an Atmel AVR RISC microprocessor, hardware asymmetric crypto engine, and internal EEPROM for RSA key storage. The device communicates via a 33MHz Low Pin Count (LPC) bus and includes a FIPS 140-2 compliant Random Number Generator. It operates on a 3.3V supply voltage and supports SIRQ and CLKRUN features for mobile power management.

Feature Summary
