AT97SC3205T-H3M4C00B

Overview

The AT97SC3205T-H3M4C00B is a Trusted Platform Module (TPM) compliant with the 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 operates at 3.3V via I2C interface supporting 400kHz Fast Mode and 100kHz Standard Mode. It includes a FIPS-140-2 certified RNG, HMAC, AES, SHA, and RSA engines. 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 Operation: 400kHz Fast Mode / 100kHz Standard Mode

Applications

Embedded systems requiring trusted platform module integration
Secure hardware and firmware design implementations
Systems utilizing high-quality random number generation for key generation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to confirm package type and temperature range. Confirm availability status as product lifecycles may change. Ensure compatibility with existing system voltage requirements of 3.3V before procurement.

Selection Notes

Select based on required package style: 28-lead Thin TSSOP or 32-pad QFN. Verify operational temperature range needs against Commercial (0°C to 70°C) or Industrial (-40°C to 85°C) options. Ensure I2C pull-up values are appropriate for 400kHz operation, specifically noting recommended values like 800Ω for SM_DAT.

Part Context

This component belongs to the AT97SC3205T series of security ICs designed by Microchip Technology (formerly Atmel). It serves as a single-chip turnkey solution for embedding trust into embedded systems through standardized TPM protocols and cryptographic functions.

Replacement Considerations

Consult the AT97SC3205T Summary Part Number Selection Guide for equivalent part numbers. Verify pinout compatibility between 28-pin TSSOP and 32-pin QFN variants if substituting package types within the same family.
