CONNECTING TO THE SPI BUS

These devices are fully compatible with the SPI

protocol.

All instructions, addresses and input data bytes

are shifted in to the device, most significant bit

first. The Serial Data Input (D) is sampled on the

first rising edge of the Serial Clock (C) after Chip

Select (S) goes Low.

All output data bytes are shifted out of the device,

most significant bit first. The Serial Data Output

(Q) is latched on the first falling edge of the Serial

Clock (C) after the instruction (such as the Read

from Memory Array and Read Status Register in-

structions) have been clocked into the device.

Figure 4. shows three devices, connected to an

MCU, on a SPI bus. Only one device is selected at

a time, so only one device drives the Serial Data

Output (Q) line at a time, all the others being high

impedance.

Note: The Write Protect (W) and Hold (HOLD) signals should be driven, High or Low as appropriate.
