CAT24C02, CAT24C04, CAT24C08, CAT24C16 EEPROM Serial 2 2/4/8/16 Kb I C Description The CAT24C02/04/08/16 are 2Kb, 4 Kb, 8 Kb and 16 Kb www.onsemi.com 2 respectively I C Serial EEPROM devices organized internally as 16/32/64 and 128 pages respectively of 16 bytes each. All devices 2 support both the Standard (100 kHz) as well as Fast (400 kHz) I C protocol. UDFN8EP Data is written by providing a starting address, then loading 1 to 16 SOIC8 WIDE HU4 SUFFIX contiguous bytes into a Page Write Buffer, and then writing all data to X SUFFIX CASE 517AZ nonvolatile memory in one internal write cycle. Data is read by CASE 751BE providing a starting address and then shifting out data serially while automatically incrementing the internal address count. External address pins make it possible to address up to eight TSSOP8 TSOT23 CAT24C02, four CAT24C04, two CAT24C08 and one CAT24C16 Y SUFFIX TD SUFFIX device on the same bus.
