AT24C512B-PU [Microchip]

The AT24C512B is a 512Kbit serial EEPROM optimized for industrial and commercial applications requiring low-power and low-voltage operation. It operates at 1.8V to 3.6V or 2.5V to 5.5V, features a two-wire serial interface with Schmitt triggers and filtered inputs for noise suppression, supports bidirectional data transfer, and offers write protect for hardware and software data protection. It includes a 128-byte page write mode with partial page writes allowed, self-timed write cycles of 5 ms max, high reliability with 1,000,000 write cycles endurance and 40 years data retention, and is available in multiple space-saving packages including PDIP, SOIC, TSSOP, dBGA2, and Ultra Thin SAP. The device is lead-free and halogen-free.
