AT97SC3204-X2MA-10

Overview

The AT97SC3204-X2MA-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 features a 33MHz Low Pin Count (LPC) bus interface, supporting SIRQ and CLKRUN for mobile power savings. It includes a FIPS 140-2 compliant Random Number Generator and provides 1756 bytes of non-volatile user-defined data storage. Operating on a 3.3V supply, it supports commercial (0°C to 70°C) and industrial (-40°C to +85°C) temperature ranges.

Feature Summary

• Fully compliant with TCG TPM version 1.2 and TCG PC Client-specific TIS version 1.2 specifications.
• Integrates an Atmel AVR RISC microprocessor with a hardware asymmetric crypto engine for RSA signatures.
• Features a 33MHz LPC bus interface with support for SIRQ interrupts and CLKRUN clock stopping.
• Includes a FIPS 140-2 compliant internal Random Number Generator (RNG) and 1756 bytes of NV storage.

Applications

• Personal computers requiring trusted platform module integration.
• Embedded systems needing secure hardware and firmware design.
• Mobile computers utilizing LPC power-saving features like CLKRUN.

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature range. Confirm availability through authorized distributors as lead times may vary. Ensure compliance with RoHS standards if required by the application environment.

Selection Notes

Select this component for applications requiring TCG TPM 1.2 compliance and LPC interface connectivity. Consider the 28-lead thin TSSOP package for space-constrained designs. Verify that the operating temperature range meets the environmental requirements of the target system.

Part Context

The AT97SC3204 series serves as a turnkey security solution for OEMs and ODMs, integrating firmware directly onto the chip. It is designed for easy integration into PCs and embedded systems, providing necessary drivers and BIOS support for initialization and verification during board assembly.

Replacement Considerations

Check for updated versions within the AT97SC3204 family or alternative TPM solutions from Microchip that maintain TCG 1.2 compatibility and LPC interface support. Ensure pinout and package dimensions match the existing design constraints.
