DESCRIPTION The IS24C02A, IS24C04A, IS24C08A, and IS24C16A are electrically erasable PROM devices that use the standard 2-wire interface for communications. The IS24C02A, IS24C04A, IS24C08A, and IS24C16A contain a memory array of 2K-bits (256 x 8), 4K-bits (512 x 8), 8K-bits (1,024 x 8), and 16K-bits (2,048 x 8), respectively. Each device is organized into 16 byte pages for page write mode.
