General Description
?
8-lead PDIP/SOP/MSOP/TSSOP, 8-pad DFN, and SOT23-5
packages
The K24C02C/K24C04/K24C08C/K24C16B provides 2048/4096/8192/16384 bits of serial electrically erasable and
programmable read-only memory (EEPROM) organized as 256/512/1024/2048 words of 8 bits each. The device is
optimized for use in many industrial and commercial applications where low-power and low-voltage operation are
essential. The K24C02C/K24C04/K24C08C/K24C16B is available in space-saving 8-lead PDIP , 8-lead SOP, 8-lead
MSOP, 8-lead TSSOP, 8-pad DFN, and SOT23-5 packages and is accessed via a two-wire serial interface.
