AT97SC3204T-X2MB-10

Overview

The AT97SC3204T-X2MB-10 is a Trusted Platform Module (TPM) compliant with TCG TPM version 1.2 and TCG PC Client-specific TPM Interface Specification (TIS) version 1.2. It integrates an Atmel AVR RISC microprocessor, hardware asymmetric crypto engine, and internal EEPROM for RSA keys. The device features a 33MHz Low Pin Count (LPC) interface, FIPS 140-2 compliant RNG, and 1756 bytes of NV storage. Operating at 3.3V, it supports commercial (0 to 70°C) and industrial (-40 to +85°C) ranges.

Feature Summary

• Fully compliant with TCG TPM v1.2 and TCG PC Client-specific TIS v1.2 specifications
• Hardware crypto engine computes 2048-bit RSA signature in 200ms and 1024-bit in 40ms
• SHA-1 accelerator performance of 20μs per 64-byte block
• Integrated AVR 8-bit RISC CPU with dynamic internal memory management for multiple RSA keys

Applications

• Personal computers requiring hardware-based security modules
• Embedded systems needing trusted platform functionality
• Mobile computers utilizing SIRQ and CLKRUN for power savings

Procurement Notes

Verify the specific package type associated with the X2MB suffix against official Microchip documentation, as the summary datasheet lists 28X1 (thin TSSOP), wide TSSOP, and 40ML1 (QFN). Confirm temperature range requirements match the commercial or industrial grades defined in the ordering information section.

Selection Notes

Select based on required operating temperature range: commercial (0 to 70°C) or industrial (-40 to +85°C). Ensure system design accommodates the 3.3V supply voltage and LPC bus interface. Verify that the chosen package variant fits the PCB layout constraints for either the 28-lead TSSOP or 40-pad QFN form factors.
