Description
/CS
Input
Chip Select: This active low input activates the device. When high, the device enters
low-power standby mode, ignores other inputs, and all outputs are tri-stated. When
low, the device internally activates the SCK signal. A falling edge on /CS must occur
prior to every op-code.
SCK
Input
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. Since the device is static, the
clock frequency may be any value between 0 and 20 MHz and may be interrupted at
any time.
/HOLD
Input
Hold: 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.
/WP
Input
Write Protect: This active low pin prevents write operations to the status register only.
A complete explanation of write protection is provided on pages 6 and 7.
SI
Input
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 IDD specifications.
* SI may be connected to SO for a single pin data interface.
SO
Output
Serial Output: This is the data output pin. It is driven during a read and remains tri-
stated at all other times including when /HOLD is low. Data transitions are driven on
the falling edge of the serial clock.
* SO may be connected to SI for a single pin data interface.
