AT97SC3205-G3M4510B

Overview

The AT97SC3205-G3M4510B is a Trusted Platform Module (TPM) compliant with TCG TPM Version 1.2 and TIS Version 1.3 specifications. It features an integrated hardware asymmetric crypto engine, an Atmel AVR RISC microprocessor, and internal EEPROM storage for RSA keys. The device communicates via the Serial Peripheral Interface (SPI) protocol at frequencies up to 45MHz. It includes FIPS-140-2 certified modules for RNG, HMAC, AES, SHA, and RSA operations, along with 2066 bytes of non-volatile user-defined data storage. The component operates on a 3.3V supply voltage.

Feature Summary

Compliant with TCG TPM Version 1.2 and TIS Version 1.3
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
Security modules requiring physical presence indicators

Procurement Notes

Verify package availability as the component is offered in both 28-lead Thin TSSOP and 32-pad QFN configurations. Confirm temperature range requirements against commercial (0°C to 70°C) and industrial (-40°C to +85°C) options. Ensure ordering codes match specific suffixes for package type and operating range.

Selection Notes

Select based on required interface speed and environmental conditions. The SPI clock frequency typically ranges from 24MHz to 33MHz in PC applications. Ensure proper decoupling capacitors (2200pF to 4700pF) are placed within 5mm of VCC pins. Unused GPIO pins should be configured according to internal pull-up or pull-down resistor states.

Part Context

This component belongs to the AT97SC3205 series of security modules designed for integration into OEM and ODM manufacturing environments. It provides a turnkey solution with integrated firmware and necessary device drivers for operating system integration. The module supports BIOS drivers and manufacturing support software for initialization and verification during board assembly.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing TPM implementations and ensure replacement parts meet TCG Version 1.2 specification requirements.
