The IS24C128 is an electrically erasable PROM device that uses the standard 2-wire interface for communications. The IS24C128 contains a memory array of 128K-bits (16,384 x 8), and is further subdivided into 256 pages of 64 bytes each for pagewrite mode. This EEPROM is offered in operating voltages of 2.5V to 5.5V (IS24C128-3) to be compatible with most application voltages. ISSI designed the IS24C128 to be a low-cost and low-power 2-wire EEPROM solution. The devices are packaged in 8-pin PDIP and 8-pin SOIC.
