DescriptionDuring all operations, VCC must be held stable and within the specified valid range: VCC(min) to VCC(max). All of the input and output signals of M95640-R must be held
High or Low (according to voltages of VIH, VOH, VIL or VOL, as specified in Table 16. to Table 20.).These signals of M95640-R are described nextSerial 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 in-structions, addresses, and the data to be written. Values are latched on the rising edge of Serial Clock (C).
Serial Clock (C). This input signal of M95640-R provides the timing of the serial interface. Instructions, address-es, 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 edge of Serial Clock (C).
