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.
The AT24C512 is a 512‑Kbit (65,536 × 8) serial EEPROM with low‑voltage and standard‑voltage operation. It supports a two‑wire I²C‑compatible interface, 128‑byte page write mode, and up to four devices can be cascaded on the same bus.
The document provides electrical characteristics, pin configurations, timing diagrams, mechanical dimensions, and contact information for Atmel. It also lists absolute maximum ratings, endurance, data retention, and recommended operating conditions.
