AT97SC3204-X2A12-10

Overview

The AT97SC3204-X2A12-10 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 keys. 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

• Compliant with TCG TPM Version 1.2 and TIS Version 1.2 specifications
• Hardware asymmetric crypto engine supporting 2048-bit RSA in 200ms
• Internal EEPROM storage for RSA keys and 1756 bytes of user-defined data
• Integrated FIPS 140-2 compliant high-quality Random Number Generator

Applications

• Personal computer security integration
• Embedded system authentication
• Mobile computer platforms requiring clock stopping capabilities

Procurement Notes

Verify package configuration against the specific suffix requirements. Confirm operating temperature range alignment with the target application environment. Ensure LPC interface compatibility with the host platform controller hub. Review the complete datasheet addendum for full catalog number ordering codes and detailed electrical characteristics.

Selection Notes

Select based on required package type, such as 28-lead thin TSSOP or 40-pad QFN. Verify that the industrial (-40 to +85°C) or commercial (0 to 70°C) temperature rating matches system constraints. Ensure the host system supports the 33MHz LPC bus protocol and provides necessary pull-up resistors for proper operation.

Part Context

This component belongs to the AT97SC3204 series of Trusted Platform Modules manufactured by Microchip Technology (formerly Atmel). The series provides turnkey security solutions for PC clients and embedded systems, featuring integrated firmware and cryptographic accelerators designed to meet industry-standard security protocols.

Replacement Considerations

Consult the official datasheet addendum for confirmed substitute part numbers. Verify pinout compatibility and package dimensions before substitution. Ensure replacement components maintain compliance with TCG TPM 1.2 specifications.
