The Microchip AT97SC3204-U2MA-20 is a dedicated security microcontroller from the CryptoController™ series, purpose-built as a Trusted Platform Module (TPM). It integrates an AVR core with dedicated cryptographic hardware and secure non-volatile storage (EEPROM program memory) to provide a hardware root of trust for platform authentication, secure boot, and key management. The LPC (Low Pin Count) interface ties it directly to the LPC bus of x86-based motherboards, embedded PCs, and server platforms that require a discrete TPM for measured boot and attestation.
Industrial temperature range — what it means for deployment
It can be specified into outdoor telecom base stations, industrial controllers in unheated enclosures, and automotive cabin-zone electronics where the ambient temperature stays within that band. The 3.3V supply rail is standard for the LPC bus and most platform controllers, so no extra voltage translation is needed.
Package and footprint notes for the layout
The LPC interface signals are on the outer perimeter pins; no special impedance control is needed for the 33 MHz LPC clock, but keep the trace short to the LPC header or chipset.
