Product Summary
The m24256-bwmn6tp is an I2C-compatible electrically erasable programmable memory (EEPROM). The m24256-bwmn6tp is organized as 32K x 8 bits. I2C uses a two-wire serial interface, comprising a bi-directional data line and a clock line. The m24256-bwmn6tp carrys a built-in 4-bit Device Type Identifier code (1010) in accordance with the I2C bus definition. The m24256-bwmn6tp behaves as a slave in the I2C protocol, with all memory operations synchronized by the serial clock. Read and Write operations are initiated by a Start condition, generated by the bus master. When writing data to the memory, the device inserts an acknowledge bit during the 9th bit time, following the bus masters 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.
