Memory addressing
To start communication between the bus master and the slave device, the bus master must
initiate a Start condition. Following this, the bus master sends the device select code, shown
in
The device select code consists of a 4-bit device type identifier, and a 3-bit Chip Enable
“Address” (E2, E1, E0). To address the memory array, the 4-bit device type identifier is
1010b.
Up to eight memory devices can be connected on a single I
unique 3-bit code on the Chip Enable (E0, E1, E2) inputs. When the device select code is
received, the device only responds if the Chip Enable Address is the same as the value on
the Chip Enable (E0, E1, E2) inputs.
The 8
If a match occurs on the device select code, the corresponding device gives an
acknowledgment on Serial Data (SDA) during the 9
the device select code, it deselects itself from the bus, and goes into Standby mode.
