VP2 SUFFIX HU4 SUFFIX All devices support both the Standard (100 kHz) as well as Fast CASE 511AK CASE 517AZ 2 (400 kHz) I C protocol. Data is written by providing a starting address, then loading 1 to 16 contiguous bytes into a Page Write Buffer, and then writing all data to nonvolatile memory in one internal write cycle. Data is read by TSOT23 MSOP8 providing a starting address and then shifting out data serially while TD SUFFIX Z SUFFIX CASE 419AE automatically incrementing the internal address count. CASE 846AD External address pins make it possible to address up to eight CAT24C01 or CAT24C02, four CAT24C04, two CAT24C08 and one WLCSP4** CAT24C16 device on the same bus.
