PIN DESCRIPTIONS
After detection of a Start condition the specified number
of clock cycles (respectively low-to-high transitions of

CLK) must be provided. These clock cycles are
required to clock in all opcode, address, and data bits
before an instruction is executed (see Table 1-3
through Table 1-6 for more details). CLK and DI then
become “don't care” inputs waiting for a new Start
condition to be detected.

CS must go low between consecutive
instructions, except when performing a
sequential read (Refer to Section 3.1
“READ” for more detail on sequential
reads).
Data In (DI)
V CC
Power Supply
Data In is used to clock in a Start bit, opcode, address
and data synchronously with the CLK input.

Chip Select (CS)
4.4
Data Out (DO)
A high level selects the device. A low level deselects
the device and forces it into Standby mode. However, a
programming cycle which is already initiated will be
completed, regardless of the CS input signal. If CS is
brought low during a program cycle, the device will go
into Standby mode as soon as the programming cycle
is completed.
CS must be low for 250 ns minimum (T CSL ) between
Data Out is used in the Read mode to output data
synchronously with the CLK input (T PD after the
positive edge of CLK).
This pin also provides Ready/Busy status information
during erase and write cycles. Ready/Busy status infor-
mation is available when CS is high. It will be displayed
until the next Start bit occurs as long as CS stays high.

control logic is held in a Reset status.

positive edge of CLK. Data bits are also clocked out on
the positive edge of CLK.
4.6
Program Enable (PE)
CLK can be stopped anywhere in the transmission
sequence (at high or low level) and can be continued
anytime with respect to clock high time (T CKH ) and
clock low time (T CKL ). This gives the controlling master
freedom in preparing opcode, address and data.
CLK is a “don't care” if CS is low (device deselected). If
CS is high, but Start condition has not been detected,
any number of clock cycles can be received by the
device without changing its status (i.e., waiting for Start
condition).
CLK cycles are not required during the self-timed
WRITE (i.e., auto erase/write) cycle.

This pin allows the user to enable or disable the ability
to write data to the memory array. If the PE pin is
floated or tied to V CC , the device can be programmed.
If the PE pin is tied to V SS , programming will be
inhibited. There is an internal pull-up on this device that
enables programming if this pin is left floating.
