The AT24MAC402 is a 2-Kbit (256 x 8) serial EEPROM that operates over a supply voltage range of 1.7V to 5.5V, making it suitable for low-voltage applications. It features an I¬=C-compatible (2-wire) interface with a maximum clock frequency of 1MHz. The device is designed for industrial and commercial applications, with an operating temperature range of -40¬8C to 85¬8C. This EEPROM includes a factory-programmed EUI-48 address and a unique 128-bit serial number, both of which are permanently write-protected. It supports hardware write protection via an external pin and offers both permanent and reversible software write protection for the first half of the memory array. The device is available in multiple package options, including 8-lead SOIC, 8-lead TSSOP, 8-pad UDFN, and 5-lead SOT23, and is compliant with RoHS standards. With an endurance of 1,000,000 write cycles and a data retention period of 100 years, the AT24MAC402 is a reliable choice for applications requiring long-term data storage.
