Datasheet
The M24164 is a 16 Kbit (2048 x 8) electrically erasable programmable memory (EEPROM) accessed by an I2C-compatible bus. It supports a two-wire I2C serial interface with a 400 kHz protocol. The device operates on a single supply voltage of 4.5V to 5.5V for M24164 or 2.5V to 5.5V for M24164-W. It features write control input, byte and page write (up to 16 bytes), random and sequential read modes, self-timed programming cycle, automatic address incrementing, enhanced ESD/latch-up behavior, more than 1 million erase/write cycles, and more than 40 years of data retention.
