AT97SC3205T-H3M4C20B

Overview

The AT97SC3205T-H3M4C20B is a Trusted Platform Module (TPM) compliant with TCG TPM Version 1.2 specifications. It integrates an Atmel AVR RISC microprocessor, hardware asymmetric crypto engine, and internal EEPROM for RSA key storage. The device supports I2C communication at 400kHz Fast Mode or 100kHz Standard Mode. It features FIPS-140-2 certification for its RNG, HMAC, AES, SHA, and RSA engines. Operating on a 3.3V supply, it provides 2066 bytes of NV user-defined data storage. Available in 28-lead Thin TSSOP or 32-pad QFN packages, it operates within commercial (0°C to 70°C) and industrial (-40°C to 85°C) temperature ranges.

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 trusted platform module integration
Secure hardware and firmware design implementations
Applications requiring certified random number generation and cryptographic operations

Procurement Notes

Verify the specific ordering suffix against the official AT97SC3205T datasheet addendum for complete catalog details. Confirm package type availability (28-pin Thin TSSOP or 32-pin Very Thin QFN) and operational range (Commercial or Industrial) required for the target application environment.

Selection Notes

Select based on interface requirements, as this model utilizes the I2C protocol. Ensure the system design accommodates the 3.3V supply voltage and appropriate decoupling capacitors (2200pF to 4700pF) near VCC pins. Consider the physical presence pin configuration if hardware security indicators are necessary for the deployment.

Part Context

This component belongs to the AT97SC3205T series of fully integrated security modules. It serves as a single-chip turnkey solution for implementing TPM functionality in embedded devices. The series includes variants with different interfaces, such as SPI, but this specific part number denotes the I2C interface version.

Replacement Considerations

Consult the AT97SC3205T Summary Part Number Selection Guide for verified substitutes. Ensure any replacement maintains TCG TPM 1.2 compliance and matches the required package and temperature range.
