General Description
The K24C128/K24C256/K24C512 provides 131,072/262,144/524,288 bits of serial electrically erasable and programmable
read-only memory (EEPROM), organized as 16,384/32,768/65,536 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 K24C128
/K24C256/K24C512 is available in space-saving 8-lead PDIP, 8-lead SOP, and 8-lead TSSOP packages and is accessed
via a two-wire serial interface. In addition, the K24C128/K24C256/K24C512 is available in 1.7V (1.7V to 5.5V) version.
