AT97SC3205T-H3M4C10B

Overview

The AT97SC3205T-H3M4C10B 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 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. The component operates on a 3.3V supply voltage and includes 2066 bytes of NV storage for user-defined data.

Feature Summary

FIPS-140-2 Certified Hardware Crypto Engine (RNG, HMAC, AES, SHA, RSA)
Integrated Atmel AVR RISC Microprocessor with Internal EEPROM
I2C Interface supporting 400kHz Fast Mode and 100kHz Standard Mode

Applications

Embedded system security modules
Hardware physical presence indicators
Secure authentication devices

Procurement Notes

Verify the specific ordering suffix against the manufacturer's summary catalog to confirm package type and temperature range. Confirm availability status as lead times may vary based on production schedules. Ensure compatibility with existing I2C pull-up configurations for stable operation at rated speeds.

Selection Notes

Select between 28-lead Thin TSSOP or 32-pad QFN packages based on board layout constraints. Verify operational temperature requirements against Commercial (0°C to 70°C) or Industrial (-40°C to 85°C) ratings. Ensure adequate decoupling capacitors (2200pF to 4700F) are placed close to VCC pins to maintain signal integrity.

Part Context

This component belongs to the AT97SC3205T series of security ICs designed for embedded systems. It serves as a single-chip turnkey solution for implementing trusted platform functionalities without requiring external cryptographic hardware.

Replacement Considerations

Consult the AT97SC3205T Summary Part Number Selection Guide for alternative ordering codes within the same family that may offer different packaging or temperature grades.
