AT97SC3205T-G3M4400B

Overview

The AT97SC3205T-G3M4400B is a fully integrated security module 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 via I2C interface at 400kHz Fast Mode or 100kHz Standard Mode with a 3.3V supply voltage. It includes FIPS-140-2 certified modules for RNG, HMAC, AES, SHA, and RSA engines, providing 2066 bytes of NV storage for user-defined data.

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 supporting 400kHz Fast Mode/100kHz Standard Mode

Applications

Embedded systems requiring trusted platform module integration
Hardware physical presence indication
Secure key generation and management

Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors. Confirm package type availability as the device is offered in 28-lead Thin TSSOP or 32-pad QFN packages. Ensure environmental compliance documentation matches project requirements.

Selection Notes

Select based on required operating temperature range: Commercial (0°C to 70°C) or Industrial (-40°C to +85°C). Choose between 28-pin Thin TSSOP or 32-pin Very Thin QFN packages according to PCB layout constraints. Verify I2C pull-up resistor values for stable communication at rated speeds.

Part Context

This component belongs to the AT97SC3205T series of Trusted Platform Modules manufactured by Microchip Technology (formerly Atmel Corporation). The series provides single-chip turnkey solutions for embedded security applications.

Replacement Considerations

Consult official Microchip Technology documentation for verified substitute part numbers within the AT97SC3205T family. Cross-reference package options and temperature ranges when selecting alternatives.
