AT97SC3205T-G3M4420B

Overview

The AT97SC3205T-G3M4420B is a security IC 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 key storage. The device operates on a 3.3V supply and supports I2C communication at 100kHz Standard Mode or 400kHz Fast Mode. It includes a FIPS-140-2 certified high-quality Random Number Generator (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
Applications utilizing hardware RNG for key generation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to confirm package type and temperature range. Confirm RoHS compliance status and check for any product change notices (PCN) related to assembly or marking changes before finalizing procurement plans.

Selection Notes

Select based on required interface speed (Standard vs. Fast Mode I2C) and operating temperature range (Commercial 0°C to 70°C or Industrial -40°C to 85°C). Ensure adequate decoupling capacitance (2200pF to 4700F) near VCC pins to maintain signal integrity at 400kHz operation.

Part Context

This component belongs to the AT97SC3205T series of Trusted Platform Modules. It serves as a single-chip turnkey solution for embedded security, combining cryptographic processing with non-volatile memory management for secure boot and identity verification protocols defined by the TCG.

Replacement Considerations

Consult the AT97SC3205T Summary Part Number Selection Guide for alternative package options or temperature grades within the same family. Verify pin compatibility if substituting between TSSOP and QFN variants.
