The IS34C02 is an electrically erasable PROM device that uses the standard 2-wire interface for communications. The IS34C02 contains a memory array of 2,048-bits (256 x 8), and is further subdivided into 16 pages of 16 bytes each for page-write mode. The software write-protection feature is initiated with a unique irreversible instruction. After this command is transmitted, the first 128 bytes of the array become permanently read-only. This feature is popular in applications like DRAM DIMMs to retain DRAM related data. This EEPROM operates in a wide voltage range of 1.8V to 5.5V to be compatible with most application voltages. ISSI designed the IS34C02 as a low-cost and low-power 2-wire EEPROM solution. The devices are packaged in 8-pin SOIC, and 8-pin TSSOP, and 8-pin MSOP.
