AT24MAC and AT24CS EEPROM Devices
Feature-enhanced serial EEPROM devices from Microchip
Microchip's AT24MAC series of devices provide pre-programmed media access control (MAC)/extended unique identifier (EUI) node identity addresses, alleviating the need for customers to program their own MAC/EUI addresses and maintain the associated complex databases, making it simpler, faster, and less expensive to develop Internet-connected products of all types.
Microchip's AT24CS series of devices includes unique, factory programmed, read-only serial numbers that can help customers simplify inventory control of mass production lines and enhance product traceability.
