AT97SC3205T-U3A1610B

Overview

The AT97SC3205T-U3A1610B 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 NV storage for user-defined data.

Feature Summary

Compliant with Trusted Computing Group (TCG) TPM Version 1.2 Specification
Integrated Atmel AVR RISC Microprocessor with Hardware Asymmetric Crypto Engine
FIPS-140-2 Certified RNG, HMAC, AES, SHA, and RSA Engines
I2C Interface supporting 400kHz Fast Mode and 100kHz Standard Mode

Applications

Embedded systems requiring secure authentication
Hardware physical presence detection
Secure boot and platform integrity verification

Procurement Notes

Verify the specific ordering suffix U3A1610B against official Microchip documentation to confirm package type and temperature range. Confirm availability status as some variants may be discontinued or have restricted supply. Ensure compatibility with existing I2C pull-up configurations for stable operation at rated speeds.

Selection Notes

Select this component for applications requiring TCG TPM 1.2 compliance with I2C connectivity. Choose between 28-lead Thin TSSOP or 32-pad QFN packages based on board space constraints. Verify that the operational temperature range meets system requirements, as commercial and industrial options are available within the family.

Part Context

This part belongs to the AT97SC3205T series of security ICs manufactured by Microchip Technology (formerly Atmel). The series offers single-chip turnkey solutions for embedded security. Variants differ primarily in package style (TSSOP vs. QFN), operating temperature ranges, and specific manufacturing lot codes indicated by the suffix.

Replacement Considerations

Direct replacements must maintain TCG TPM 1.2 compliance and I2C interface compatibility. Consider the AT97SC3205T-SDK2 development kit for evaluation purposes. Verify pinout compatibility if substituting with other packages in the same family.
