AT97SC3205-H3M45-00

Overview

The AT97SC3205-H3M45-00 is a Trusted Platform Module (TPM) 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 supports the SPI protocol at up to 45MHz and includes a FIPS-140-2 certified high-quality Random Number Generator (RNG). It provides 2066 bytes of non-volatile user-defined data storage and operates on a 3.3V supply voltage.

Feature Summary

• Compliant with TCG TPM 1.2 and TIS 1.3 specifications
• Hardware asymmetric crypto engine with FIPS-140-2 certification
• Internal EEPROM storage for RSA keys and 2066 bytes NV user data
• SPI interface supporting clock speeds up to 45MHz

Applications

• Personal computer security modules
• Embedded systems requiring hardware authentication
• Secure boot implementations

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog, as the provided summary document references a separate addendum for complete part number codes. Confirm package availability, as the base model supports both 28-pin thin TSSOP and 32-pad QFN options. Ensure compatibility with the required operating temperature range before procurement.

Selection Notes

Select based on the required package type: 28X1 for 28-lead thin TSSOP or 32M3 for 32-pad QFN. Verify the operating temperature range requirement, as the device is offered in Commercial (0°C to 70°C) and Industrial (-40°C to +85°C) variants. Ensure the system design accommodates the 3.3V supply voltage and appropriate SPI bus timing constraints.

Part Context

This component belongs to the AT97SC3205 series of security ICs designed by Microchip Technology (formerly Atmel). It serves as a single-chip turnkey solution for implementing trusted platform functionality in embedded devices. The series focuses on providing secure hardware and firmware integration for cryptographic operations and identity management.

Replacement Considerations

Consult the official Microchip/Atmel cross-reference documentation for verified compatible replacements. Consider pinout compatibility if substituting packages (TSSOP vs. QFN). Verify that any replacement maintains compliance with TCG TPM 1.2 and TIS 1.3 standards.
