SIGNAL DESCRIPTION
V
V
All of the input and output signals can be held High
or Low (according to voltages of V
V
nals are described next.
Serial Data Output (Q)
This output signal is used to transfer data serially
out of the device. Data bytes are shifted out on the
falling edge of the Serial Clock (C).
Serial Data Input (D)
This input signal is used to transfer data serially
into the device. Instructions, addresses, and input
data bytes are shifted in on the rising edge of the
Serial Clock (C).
Serial Clock (C)
This input signal provides the timing for the serial
interface.

Chip Select (S)
When this input signal is High, the device is dese-
lected, and the Serial Data Output (Q) is high im-
pedance.
Hold (HOLD)
This input signal is used to pause temporarily any
serial communications with the device, without los-
ing bits that have already been passed on the se-
rial bus.
Write Protect (W)
This input signal is used to control whether the
memory is write protected. When W is held Low,
writes to the memory are disabled, but other oper-
ations remain enabled. No action on this signal, or
on the Write Enable Latch (WEL) bit, can interrupt
a Write cycle that has already started.
