Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's summary datasheet to confirm package type and temperature range. The complete catalog number ordering code requires reference to the full AT97SC3205T datasheet addendum. Confirm availability status directly with authorized distributors as lead times may vary based on production schedules.

Application Specific Microcontrollers Selection Notes

Select this component for applications requiring TCG TPM 1.2 compliance with I2C connectivity. Ensure the system design accommodates the 3.3V supply voltage and appropriate decoupling capacitors (2200pF to 4700pF) near VCC pins. Verify that the required operational temperature range matches the commercial or industrial variant selected.

Application Specific Microcontrollers Part Context

The AT97SC3205T series is part of Atmel's (now Microchip Technology) security IC portfolio designed for embedded systems. It serves as a single-chip turnkey solution for implementing trusted platform functionalities. The device utilizes internal dynamic memory management to store multiple RSA keys without system intervention.

Application Specific Microcontrollers Replacement Considerations

Consult the AT97SC3205 Summary Part Number Selection Guide for alternative packages such as 28-pin Thin TSSOP or 32-pad QFN. Verify pin compatibility and interface requirements before substituting with other TPM models from the same family.
