24AA256-I/S16K

Memory IC Overview

The Microchip Technology 24AA256-I/S16K is a 32K x 8 (256-Kbit) Serial Electrically Erasable PROM (EEPROM). It operates across a broad voltage range of 1.7V to 5.5V with a maximum clock frequency of 400 kHz. The device supports both random and sequential reads up to the 256K boundary and features a page write capability of up to 64 bytes. Functional address lines allow up to eight devices on the same bus, providing up to 2 Mbit address space.
