Description
The M24256-Bx devices are I2C-compatible electrically erasable programmable memories
(EEPROM). They are organized as 32 Kb × 8 bits.
The M24256-Bx and M24256-DR can decode the type identifier code (1010) in accordance
with the I2C bus definition. The M24256-DR also decodes the type identifier code (1011)
when accessing the identification page.
The device 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. The Start condition is followed by a device select code and Read/Write
bit (RW) (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.
