AT97SC3205T-H3M4B20B

Overview

The AT97SC3205T-H3M4B20B is a security integrated circuit implementing the Trusted Computing Group (TCG) Trusted Platform Module (TPM) Version 1.2 specification. It operates on a 3.3V supply voltage and utilizes an I2C interface supporting 100kHz Standard Mode and 400kHz Fast Mode. The device integrates an Atmel AVR RISC microprocessor, hardware asymmetric crypto engine, and internal EEPROM storage for RSA keys. It provides 2066 bytes of non-volatile user-defined data storage and includes a FIPS-140-2 certified high-quality random number generator.

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 and 2066 Bytes User Data
I2C Interface: 100kHz Standard Mode / 400kHz Fast Mode

Applications

Embedded System Security Modules
Trusted Platform Module Implementations
Secure Authentication Devices

Procurement Notes

Verify the specific ordering suffix H3M4B20B against official Microchip Technology documentation to confirm package type and temperature range. Confirm current lifecycle status as the summary datasheet indicates potential variations in availability. Ensure compatibility with system I2C pull-up requirements for stable communication at rated speeds.

Selection Notes

Select this component for applications requiring TCG TPM 1.2 compliance with I2C connectivity. Verify that the system supports the required 3.3V supply voltage and can accommodate the specific package dimensions (28-lead Thin TSSOP or 32-pad QFN). Ensure firmware integration aligns with the AVR RISC architecture and available NV storage capacity.

Part Context

This part belongs to the AT97SC3205T series of Trusted Platform Modules manufactured by Microchip Technology (formerly Atmel). The series offers single-chip turnkey solutions for embedded security, featuring hardware cryptographic engines and secure firmware design compliant with industry standards.

Replacement Considerations

Consult the AT97SC3205T Summary Part Number Selection Guide for verified substitutes. Ensure any replacement maintains TCG TPM 1.2 compliance, I2C interface compatibility, and equivalent package footprint.
