Pin Definitions

Pin Name

I/O Type

Description

Input

Chip Select. This active LOW input activates the device. When HIGH, the device enters low-power

standby mode, ignores other inputs, and tristates the output. When LOW, the device internally

activates the SCK signal. A falling edge on CS must occur before every opcode.

SCK

SI^[1]

Serial Clock. All I/O activity is synchronized to the serial clock. Inputs are latched on the rising edge

and outputs occur on the falling edge. Because the device is synchronous, the clock frequency may

be any value between 0 and 20 MHz and may be interrupted at any time.

Serial Input. All data is input to the device on this pin. The pin is sampled on the rising edge of SCK

and is ignored at other times. It should always be driven to a valid logic level to meet I_DDspecifica-

tions.

SO^[1]

Output

Input

Serial Output. This is the data output pin. It is driven during a read and remains tristated at all other

times including when HOLD is LOW. Data transitions are driven on the falling edge of the serial clock.

Write Protect. This active LOW pin prevents write operation to the Status Register when WPEN is

set to ‘1’. This is critical because other write protection features are controlled through the Status

Protection on page 7. This pin must be tied to V_DDif not used.

HOLD

Input

HOLD Pin. The HOLD pin is used when the host CPU must interrupt a memory operation for another

task. When HOLD is LOW, the current operation is suspended. The device ignores any transition

on SCK or CS. All transitions on HOLD must occur while SCK is LOW. This pin must be tied to V_DD

if not used.

V_SS

V_DD

Power supply Ground for the device. Must be connected to the ground of the system.

Power supply Power supply input to the device.

Note

1. SI may be connected to SO for a single pin data interface.
