Four dedicated I/O lines are available for platform control signals — typically used for physical presence, reset, and interrupt handshaking with the host chipset. The program memory is EEPROM, meaning the firmware and endorsement key are retained without external backup power. ## Active lifecycle — ROHS3, commercial temp range Microchip lists this part as Active. The Tray packaging is the standard delivery format for volume board-assembly lines; each tray holds a known quantity that maps to the pick-and-place feeder setup. ## Interface delta vs LPC peer The closest peer in the same CryptoController family is the AT97SC3204-U2MA-20, which uses an LPC (Low Pin Count) bus instead of I²C. Both parts share the AVR core, EEPROM program memory, and 3.3 V supply, but the LPC variant targets legacy chipset southbridge connections, while the I²C variant (this one) is the modern choice for embedded controllers and SoCs that expose an I²C TPM interface.","metaTitle":"Microchip AT97SC3205T-G3M4C00B TPM, I²C, 32-VQFN","metaDescription":"Microchip AT97SC3205T-G3M4C00B Trusted Platform Module, I²C interface, AVR core, 3.3V supply, 32-VQFN package.

The two parts are not pin-compatible — the bus protocol and pinout differ. A board designed for the I²C variant cannot accept the LPC variant without a layout change."},{"question":"What compliance documentation does Microchip provide for this TPM?","answer":"The part is ROHS3 compliant.
