数据手册.pdf128Kbit/ 256Kbit 2-WIRE SERIAL CMOS EEPROM
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.
