AT97SC3205T-H3M4C-20

Overview

The AT97SC3205T-H3M4C-20 is a security integrated circuit implementing the Trusted Computing Group (TCG) Trusted Platform Module (TPM) Version 1.2 specification. It features an Atmel AVR RISC microprocessor, hardware asymmetric crypto engine, and internal EEPROM storage for RSA keys. The device operates on a 3.3V supply voltage with I2C communication supporting 400kHz Fast Mode and 100kHz Standard Mode. It includes FIPS-140-2 certified modules for RNG, HMAC, AES, SHA, and RSA. The component provides 2066 bytes of NV storage for user-defined data and is available in 28-lead Thin TSSOP or 32-pad QFN packages.

Feature Summary

Compliant with TCG TPM Version 1.2 Specification
Hardware Asymmetric Crypto Engine with FIPS-140-2 Certification
Internal EEPROM Storage for RSA Keys
I2C Interface: 400kHz Fast Mode / 100kHz Standard Mode

Applications

Embedded systems requiring hardware-based authentication
Trusted Platform Modules for PC clients
Secure key storage and management applications

Procurement Notes

Verify the specific ordering suffix H3M4C-20 against the manufacturer's current catalog to confirm package type and temperature range availability. Confirm RoHS compliance status and check for any product discontinuation notices or lifecycle changes directly from Microchip Technology before finalizing procurement plans.

Selection Notes

Select this component for designs requiring TCG TPM 1.2 compliance with I2C interface connectivity. Ensure the system design accommodates the 3.3V supply voltage and provides appropriate decoupling capacitors (2200pF to 4700pF) near VCC pins. Verify that the chosen package (TSSOP or QFN) fits the PCB layout constraints and thermal requirements.

Part Context

This part belongs to the AT97SC3205T family of Trusted Platform Modules manufactured by Microchip Technology (formerly Atmel). The family offers single-chip turnkey solutions for security applications, integrating cryptographic engines and non-volatile memory within an AVR processor core.

Replacement Considerations

Consult the official AT97SC3205T Summary Part Number Selection Guide for verified substitute part numbers. Cross-reference package options (28-pin TSSOP vs. 32-pin QFN) and operational temperature ranges when evaluating alternatives.
