DESCRIPTION
The IS25C128A is electrically erasable PROM devices that use the Serial Peripheral Interface (SPI) for communications. The IS25C128A is 128Kbit (16K x 8). The IS25C128A EEPROMs is offered in a wide operating voltage range of 1.8V to 5.5V for compatibility with most application voltages. ISSI designed the IS25C128A to be an efficient SPI EEPROM solution. The device is offered in lead-free, RoHS, halogen free or Green. The available package types are 8-pin SOIC, TSSOP and PDIP.
