AT24C04-10PI [Microchip]

The AT24C01A/02/04/08/16 is a family of serial EEPROMs optimized for industrial and commercial applications requiring low-power and low-voltage operation. Available in space-saving 8-pin PDIP, 8-lead TSSOP, and 8-lead JEDEC SOIC packages, these devices feature a 2-wire serial interface, Schmitt trigger inputs for noise suppression, and operate at 5.0V (4.5V-5.5V), 2.7V (2.7V-5.5V), 2.5V (2.5V-5.5V), and 1.8V (1.8V-5.5V) versions. Key capabilities include write protect pin for hardware data protection, 8-byte or 16-byte page write modes, partial page writes, self-timed write cycles (10 ms max), high endurance (1 million write cycles), and 100-year data retention.
