IS24C128A-2PLI中文资料北京矽成数据手册PDF规格书

DESCRIPTION

The IS24C128A/256A is an electrically erasable PROM device that uses the standard 2-wire interface for communications. The IS24C128A is 128K-bit (16Kx8) and the IS24C256A is 256K-bit (32Kx8). These EEPROM are offered in a wide operating voltage range of 1.8V to 5.5V to be compatible with most application voltages. ISSI designed the IS24C128A/256A to be an efficient 2-wire EEPROM solution. The devices are packaged in 8-pin PDIP, 8-pin (JEDEC) SOIC, and 8-pin (EIAJ) SOIC.
