AT24C512 is a serial electrically erasable and programmable read only memory (EEPROM) with features of low power and low voltage operation. It has an internally organized structure of 65,536 x 8 bits, with a two-wire serial interface, Schmitt triggers, and filtered inputs for noise suppression. The product supports bidirectional data transfer protocol, compatibility with multiple operating voltages (2.7V to 5.5V, 1.8V to 3.6V) and different frequencies (1 MHz, 400 kHz, 100 kHz). It also features a write protect pin, 128-byte page write mode, self-timed write cycle, high reliability (100,000 write cycles, 40 years data retention), etc. It can be used in industrial and commercial applications.
