MCHPAT97SC3204-U2A1A-20
Overview
The AT97SC3204-U2A1A-20 is a Trusted Platform Module (TPM) based on an 8-bit AVR RISC core, specifically designed for secure hardware-based cryptographic functions. It is fully compliant with the Trusted Computing Group (TCG) version 1.2 specification and utilizes a Low Pin Count (LPC) interface for integration with PC-compatible architectures and embedded systems. The device features a hardware asymmetric crypto engine, a high-quality FIPS 140-2 compliant random number generator, and 1756 bytes of non-volatile EEPROM storage for user data and RSA keys.
Why Choose This Part
This single-chip turnkey solution simplifies the implementation of TCG-compliant security by offloading complex asymmetric cryptographic operations to a dedicated hardware engine. It offers 1756 bytes of internal EEPROM for secure user data and is designed with specialized hardware countermeasures to resist physical tampering. The LPC interface ensures compatibility with standard PC-client specifications, making it a drop-in security upgrade for many industrial motherboard designs.
Applications
Key Specifications
Getting Started
To integrate this TPM, ensure your host processor supports the LPC (Low Pin Count) interface and is compatible with TCG TIS version 1.2 drivers. Development typically requires a TPM software stack (TSS) like TrouSerS or WolfTPM to interact with the device via the OS kernel. Hardware prototyping is best performed on boards with a dedicated TPM header, though manual wiring of the 28-TSSOP package is possible for custom embedded applications.
