AT97SC3204-U2MA-20

Application Specific Microcontrollers Overview

The AT97SC3204-U2MA-20 is a security module implementing the Trusted Computing Group (TCG) TPM version 1.2 specification. 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 provides 1756 bytes of non-volatile user-defined data storage.

Application Specific Microcontrollers Feature Summary

• Fully compliant with TCG TPM version 1.2 and PC Client-specific TPM Interface Specification (TIS) version 1.2
• Hardware crypto engine capable of computing a 1024-bit RSA signature in 40ms and SHA-1 at 20μs per 64-byte block
• Supports SIRQ interrupts and CLKRUN for clock stopping to enable power savings in mobile computers
• Includes internal high-quality RNG compliant with FIPS 140-2 standards

Application Specific Microcontrollers Applications

• Personal computer integration
• Embedded systems requiring trusted platform functionality
• Mobile computers utilizing LPC power-saving features

Application Specific Microcontrollers Procurement Notes
