Read Only Memory (EEPROM)
communicates with the economy of one
signal plus ground
register is automatically write-protected after
programming
programming signals to a single data pin
communications requirements to reader
of 2.8V to 6.0V from -40°C to +85°C
registration number (8-bit family code + 48-
bit serial number + 8-bit CRC tester) assures
absolute traceability because no two parts are
alike
