AT97SC3203-X9M10

Overview

The AT97SC3203-X9M10 is an 8-bit Trusted Platform Module (TPM) microcontroller manufactured by Microchip Technology, formerly Atmel. It integrates an AVR RISC core with internal EEPROM storage for RSA keys and a hardware asymmetric crypto engine. The device complies with the TCG TPM Version 1.2 specification and supports the SPI protocol at frequencies up to 45 MHz. It is housed in a TSSOP-28 package and operates within a commercial temperature range of 0°C to +70°C. This component provides a secure, single-chip solution for platform authentication and data protection.

Feature Summary

• Compliant with TCG TPM Version 1.2 and TCG PC Client-Specific TIS Version 1.3 specifications
• Integrated AVR RISC microprocessor core with hardware asymmetric crypto engine
• Internal EEPROM storage dedicated to RSA key management
• Serial Peripheral Interface (SPI) support with typical operating speeds between 24 MHz and 33 MHz

Applications

• PC client platform authentication and security
• Secure boot and firmware integrity verification
• Hardware-based encryption for data at rest

Procurement Notes

The AT97SC3203 series has been officially declared End-of-Life (EOL) by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory. Designers should confirm RoHS compliance status and review specific EOL notifications from Microchip Technology before procurement planning.

Selection Notes

Select this component for applications requiring FIPS-140-2 certified TPM functionality using the SPI interface. Ensure the system design accommodates the 8-bit AVR architecture and TSSOP-28 package constraints. Verify that the host controller supports the required SPI timing parameters and voltage levels compatible with the 3.3V operation typical for this family.

Part Context

This part belongs to the AT97SC320x family of Trusted Platform Modules. It shares architectural similarities with the AT97SC3205 but differs in packaging and specific interface configurations. The 'X9' suffix typically denotes specific tape-and-reel packaging or regional variants within the broader AT97SC3203 product line managed by Microchip.

Replacement Considerations

Due to the End-of-Life status, direct replacements are limited. Evaluate the AT97SC3205 for updated availability, noting potential differences in package type (e.g., VQFN vs. TSSOP). Cross-reference with newer TPM solutions from Microchip or other vendors if long-term supply assurance is required.
