24C64 - Two-wire Serial EEPROM

Download the 24C64 datasheet PDF. This datasheet also covers the 24C32 variant, as both devices belong to the same two-wire serial eeprom family and are provided as variant models within a single manufacturer datasheet.

General 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.
