DATA SHEET www.onsemi.com EEPROM Serial 2 2/4/8/16 Kb I C UDFN8EP SOIC8 WIDE HU4 SUFFIX CAT24C02, CAT24C04, X SUFFIX CASE 517AZ CASE 751BE CAT24C08, CAT24C16 Description TSSOP8 The CAT24C02/04/08/16 are 2Kb, 4Kb, 8Kb and 16Kb TSOT23 2 Y SUFFIX respectively I C Serial EEPROM devices organized internally as TD SUFFIX CASE 948AL CASE 419AE 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. WLCSP4** Data is written by providing a starting address, then loading 1 to 16 C4A SUFFIX SOIC8 contiguous bytes into a Page Write Buffer, and then writing all data to W SUFFIX CASE 567DC nonvolatile memory in one internal write cycle. Data is read by CASE 751BD providing a starting address and then shifting out data serially while automatically incrementing the internal address count. WLCSP5** WLCSP4** External address pins make it possible to address up to eight C5A SUFFIX C4U SUFFIX CASE 567DD CASE 567NX CAT24C02, four CAT24C04, two CAT24C08 and one CAT24C16 device on the same bus. ** WLCSP are available for the CAT24C04, CAT24C08 and CAT24C16 only.
