Description
The M24256-Bx devices are I
(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 I
when accessing the identification page.
The device behaves as a slave in the I
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
When writing data to the memory, the device inserts an acknowledge bit during the 9
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.
