24C512 512 Kbit Serial I²C Bus EEPROM DIP‑8

Description

24C512 512 Kbit Serial I²C Bus EEPROM DIP‑8 The 24C512 512 Kbit Serial I²C Bus EEPROM DIP‑8 is a non‑volatile memory device organized as 65,536 × 8 bits. It operates from 1.8 V to 5.5 V and communicates via a standard two‑wire I²C‑compatible interface at up to 1 MHz. With self‑timed write cycles, hardware write‑protect, and ultra‑low standby current, it’s ideal for data logging, configuration storage, and industrial control applications Features Wide supply voltage range: 1.8–5.5 V for low‑voltage and standard‑voltage systems. Two‑wire I²C‑compatible serial interface supporting 100 kHz, 400 kHz, and 1 MHz clock rates. 128‑byte page write capability with partial‑page writes allowed. Built‑in 1 MΩ pull‑up inputs with Schmitt‑trigger filtering for noise immunity. Self‑timed write cycle (max 5 ms) and acknowledge polling for efficient operation. Hardware write‑protect pin to safeguard memory against unintended writes. High reliability: 1,000,000 write cycles and 100 years data retention.
