General Description
The
24C32/ 24C64 provides 32,768/65,536 bits of serial electrically erasable and programmable read-only memory
24C32/ 24C64 is available in
(EEPROM) organized as 4096/8192 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
space-saving 8-lead PDIP, 8-lead SOP, and 8-lead TSSOP packages and is accessed via a two-wire serial interface.
