com MX23L12854 SIGNAL DESCRIPTION Serial Data Output (Q).
This output signal is used to transfer data serially out of the device.
Data is shifted out on the falling edge of Serial Clock (C).
Serial Data Input (D).
This input signal is used to transfer data serially into the device.
It receives instructions, addresses, and the data to be programmed.
Values are latched on the rising edge of Serial Clock (C).
Serial Clock (C).
This input signal provides the timing of the serial interface.
Instructions, addresses, or data present at Serial Data Input (D) are latched on the rising edge of Serial Clock (C).
Data on Serial Data Output (Q) changes after the falling...
