Overview
The AT97SC3205T-G3M4610B 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 operates on a 3.3V supply voltage and includes a FIPS-140-2 certified high-quality Random Number Generator (RNG). The component provides 2066 bytes of non-volatile user-defined data storage.
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
Applications
- Embedded systems requiring trusted platform module integration
- Hardware physical presence indication via GPIO
- Secure random number generation for cryptographic operations
Procurement Notes
Verify the specific ordering suffix to confirm package type and temperature range. Confirm that the G3M4610B designation corresponds to the intended commercial or industrial operational range as defined in the manufacturer's catalog. Ensure compatibility with the required 3.3V power supply and I2C pull-up configurations.
Selection Notes
Select this component when a turnkey TPM solution compliant with version 1.2 is required. Choose between the 28-lead Thin TSSOP or 32-pad QFN packages based on board space constraints. Verify that the system can support the specified I2C clock speeds and that the 3.3V logic levels are compatible with the host processor.
Part Context
This part belongs to the AT97SC3205T series of security ICs manufactured by Microchip Technology (formerly Atmel). The series offers integrated security features including RNG, HMAC, AES, SHA, and RSA engines within a single chip designed for embedded applications.
Replacement Considerations
Consult the AT97SC3205 Summary Part Number Selection Guide for alternative package options or temperature ranges within the same family. Verify pinout compatibility if substituting with other variants in the AT97SC3205T series.
