AT97SC3205T-G3M46-00

Overview

The AT97SC3205T is a fully integrated security module implementing the Trusted Computing Group (TCG) Trusted Platform Module (TPM) Version 1.2 specification. It operates on a 3.3V supply voltage and features an Atmel AVR RISC microprocessor with a hardware asymmetric crypto engine. The device supports I2C communication at 400kHz Fast Mode or 100kHz Standard Mode. It includes internal EEPROM storage for RSA keys, a FIPS-140-2 certified high-quality random number generator, and 2066 bytes of non-volatile user-defined data storage. Available in 28-lead Thin TSSOP and 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 Interface supporting 400kHz Fast Mode

Applications

Embedded systems requiring hardware-based security modules
Platforms needing TCG-compliant trusted platform functionality
Devices utilizing hardware physical presence indicators

Procurement Notes

Verify package type availability as the component is offered in both 28-lead Thin TSSOP and 32-pad QFN configurations. Confirm operational temperature range requirements against Commercial (0°C to 70°C) and Industrial (-40°C to 85°C) options. Ensure decoupling capacitors meet the recommended X5R or X7R dielectric ratings for stable operation.

Selection Notes

Select the appropriate package based on board space constraints; the 28-pin TSSOP measures 4.40mm x 9.70mm while the 32-pin QFN measures 4.00mm x 4.00mm. Verify I2C pull-up resistor values, specifically noting that 800Ω on SM_DAT and 1.5KΩ on SM_CLK function properly at 400kHz speeds. Ensure GPIO pins are tied correctly if unused to maintain proper logic states.

Part Context

This component belongs to the AT97SC3205T series of Trusted Platform Modules manufactured by Microchip Technology (formerly Atmel). It serves as a single-chip turnkey solution for integrating security features into embedded systems without requiring external cryptographic components.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult official manufacturer channels for migration paths or equivalent secure elements.
