Catalyst Semiconductor Announces Cascadable 128kbit I2C Serial EEPROM.Business Editors/High-Tech Writers SUNNYVALE, Calif.--(BUSINESS WIRE)--Sept. 30, 2002 Catalyst Semiconductor (Nasdaq: CATS) today announced the availability of the CAT24AC128, a 128kbit I2C I2C Inter-Integrated Circuit I2C Intelligent Interface Controller I2C Intelligent Controller serial EEPROM (Electrically Erasable Programmable ROM) A rewritable memory chip that holds its content without power. Although EEPROMs spawned flash memory, EEPROMs are byte addressable at the write level, whereas flash chips must erase a block of bytes before rewriting. memory organized as 16,384 words of 8 bits each. Featuring three chip address lines, up to 8 devices can share a common 2-wire I2C bus. The CAT24AC128 can be used in systems that require a 1Mbit address space. Multiple write and read operating modes increase application versatility. By using the page write mode, up to 64 bytes of data can be written with a single write cycle, thus making efficient use of the system processor. The entire memory array can be hardware write protected with the WP pin. Three different read operations are possible: immediate/current address read, selective/random read and sequential read.
