The IS24C02A, IS24C04A, IS24C08A, and IS24C16A are electrically erasable PROM devices that use the standard 2-wire interface for communications. The IS24C02A, IS24C04A, IS24C08A, and IS24C16A contain a memory array of 2K-bits (256 x 8), 4K-bits (512 x 8), 8K-bits (1,024 x 8), and 16K-bits (2,048 x 8), respectively. Each device is organized into 16 byte pages for page write mode. This EEPROM operates in a wide voltage range of 1.8V to 5.5V to be compatible with most application voltages. ISSI designed this device family to be a practical, low-power 2-wire EEPROM solution. The devices are available in 8-pin PDIP, 8-pin SOIC, 8- pad DFN, 8-pin MSOP, and 8-pin TS SOP packages. The IS24C02A/04A/08A/16A maintains compatibility with the popular 2-wire bus protocol, so it is easy to use in applications implementing this bus type. The simple bus consists of the Serial Clock wire (SCL) and the Serial Data wire (SDA). Using the bus, a Master device such as a micro controller is usually connected to one or more Slave devices such as this device. The bit stream over the SDA line includes a series of bytes, which identifies a particular Slave device, an instruction, an address within that Slave device, and a series of data, if appropriate. The IS24C02A/04A/08A/16A has a Write Protect pin (WP) to allow blocking of any write instruction transmitted over the bus.
