MCHPAT97SC3205T-H3M4C-00
Overview
The AT97SC3205T is a fully integrated Trusted Platform Module (TPM) based on an 8-bit AVR RISC core, designed to provide hardware-based security for computing and embedded systems. It is compliant with the TCG TPM Version 1.2 specification and features dedicated hardware engines for RSA, SHA-1, AES, and HMAC operations. This turnkey solution includes 2066 bytes of user-defined NV storage and an I2C interface for seamless integration into 3.3V systems.
Why Choose This Part
The device is FIPS-140-2 Module Certified, ensuring high-assurance security for critical cryptographic functions like random number generation and hashing. Its compact 4x4mm VQFN package and I2C interface simplify the physical and logical integration into space-constrained embedded designs compared to LPC-based TPMs.
Applications
Key Specifications
Getting Started
To implement this TPM, engineers should utilize the Microchip TPM library and ensure the host controller supports I2C communication. Physical integration requires a 3.29V to 3.31V supply voltage and attention to the 0.4mm pitch 32-VQFN package requirements. Evaluation can be performed using the AT97SC3205T-SDK development kits which provide reference software for TCG-compliant drivers.
