Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix X3A1C10B against official Microchip documentation to confirm package type and temperature range. Confirm availability status as some variants may be discontinued or have limited stock. Ensure compatibility with existing system designs regarding I2C pull-up requirements and decoupling capacitor placement.

Application Specific Microcontrollers Selection Notes

Select this component for applications requiring TCG TPM 1.2 compliance with I2C interface. Consider the 28-lead Thin TSSOP or 32-pad QFN packages based on board space constraints. Verify operational temperature range requirements against Commercial (0°C to 70°C) or Industrial (-40°C to 85°C) options available in the product line.

Application Specific Microcontrollers Part Context

The AT97SC3205T series is part of Microchip's (formerly Atmel) security IC portfolio designed for embedded systems. It provides a single-chip turnkey solution for implementing trusted computing functions. The device integrates cryptographic engines and secure storage to protect sensitive data and authentication processes within host systems.

Application Specific Microcontrollers Replacement Considerations

Check for updated versions or alternative packages within the AT97SC3205T family. Verify pinout compatibility if substituting with other TPM devices. Ensure that any replacement maintains TCG TPM 1.2 compliance and I2C interface specifications.
