M24164

The M24164 is a 16 Kbit (2048 x 8) electrically erasable programmable memory (EEPROM) accessed by an I²C-compatible bus.

These devices are compatible with a two-wire serial interface that uses a bi-directional data bus and serial clock. By setting the three chip enables (E0, E1, E2) appropriately, up to eight 16 Kbit devices can be attached to the same I2C bus, and selected individually.

These devices behave as slave devices, with all memory operations synchronized by the serial clock. Read and Write operations are initiated by a Start condition, generated by the bus master. The Start condition is followed by a Device Select Code and RW bit (as described in Table 2), terminated by an acknowledge bit.

When writing data to the memory, the device inserts an acknowledge bit during the 9th bit time,following the bus master's 8-bit transmission. When data is read by the bus master, the bus master acknowledges the receipt of the data byte in the same way. Data transfers are terminated by a Stop condition after an Ack for Write, and after a NoAck for Read.
