IS24C128 131,072-bit 2-WIRE SERIAL CMOS EEPROM ISSI DESCRIPTION ® PRELIMINARY INFORMATION MARCH 2003 FEATURES Organization: – 16K-bit x 8-bit www.DataSheet4U.com 64-Byte Page Write Buffer Two-Wire Serial Interface – Bi-directional data transfer protocol Low Power CMOS Technology – Active Current less than 2 mA (5V) – Standby Current less than 5 µA (5V) – Standby Current less than 2 µA (2.5V) Low Voltage Operation – IS24C128-2: Vcc = 1.8V to 5.5V – IS24C128-3: Vcc = 2.5V to 5.5V 400 KHz (I2C Protocol) Compatibility Hardware Data Protection – Write Protect pin Sequential Read Feature Filtered Inputs for Noise Suppression Self time Write cycle with auto clear – 5 ms @ 2.5V High Reliability – Endurance: 100,000 Cycles – Data Retention: 40 Years Commercial and Industrial temperature ranges 8-pin PDIP, 8-pin SOIC, and 14-pin TSSOP 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 wide operating voltages of 1.8V to 5.5V (IS24C128-2) and 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, 8-pin SOIC, and 14-pin TSSOP. The IS24C128 maintains compatibility with the popular 2-wire bus p...
