Description
LR24C32/LR24C64 provides 32768/65536 bits of serial electrically erasable and
programmable read-only memory (EEPROM) organized as 4096 words of 8 bits each. The
device is optimized for use in many industrial and commercial applications where low-power
and low-voltage operations are essential. The LR24C32/LR24C64 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.
