AT97SC3205-G3M4520B

Overview

The AT97SC3205-G3M4520B is a Trusted Platform Module (TPM) security IC compliant with TCG TPM Version 1.2 and TIS Version 1.3 specifications. It integrates an Atmel AVR RISC microprocessor, hardware asymmetric crypto engine, and internal EEPROM for RSA key storage. The device communicates via the Serial Peripheral Interface (SPI) protocol at frequencies up to 45MHz. It includes a FIPS-140-2 certified high-quality Random Number Generator (RNG), HMAC, AES, SHA, and RSA engines. The component operates on a 3.3V supply voltage and 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
SPI Protocol Support Up to 45MHz

Applications

Personal Computers
Embedded Systems

Procurement Notes

Verify the specific package configuration required for the design, as the AT97SC3205 series is available in both 28-lead Thin TSSOP and 32-pad QFN packages. Confirm that the ordering suffix corresponds to the desired temperature range and package type. Ensure compatibility with the system's SPI interface timing requirements, particularly regarding the typical PC operating range of 24MHz to 33MHz.

Selection Notes

Select this component for applications requiring a turnkey TPM solution integrated into personal computers or embedded systems. The device supports both commercial (0°C to 70°C) and industrial (-40°C to +85°C) temperature ranges. Designers must account for the 3.3V supply voltage requirement and implement effective decoupling of VCC inputs using capacitors within the recommended range of 2200pF to 4700pF placed close to the chip.

Part Context

The AT97SC3205 is part of the AT97SC3205 family of security modules designed by Microchip Technology (formerly Atmel). This family offers a single-chip, turnkey solution for implementing Trusted Platform Modules. The device is intended for OEM and ODM manufacturers, providing integrated firmware and necessary device driver software for integration into various operating systems and BIOS environments.
