I/O DESCRIPTION
I Internal pull-high. Set TEST low to enable "Self-test" function.
Indicates the result of self-test process. “0” indicates a correct result; “1”
O indicates an incorrect result. At Power-On-Reset, it outputs a logic "1"
signal.
I Clock input for shift-in start address;
the first rising-edge signal resets the address counter.

Bi-directional data pin-2 with internal pull-high
IO
used for cascading address and data through the IC.
Active-low chip enable. Determines whether or not to cascade when in
address mode:
I “0”: DATA2 does not have any cascaded chips appended
“1”: DATA2 has cascaded chips appended.
I Clock input for data read-out.
Power Positive power supply pin.

2.2 W551Cxxx Serial Read Mode
The default mode is serial read mode.
The address is 24 bits long. The MSB x bits are the page code, and the remaining (24 - x) bits are the
offset address. The address data is shifted, MSB first, into the address counter by the ADDR clock,
and the device is enabled if the page code matches the content of the W551Cxxx page-code cells.
The number of bits in the page code varies by part number and is shown below.
PART # W551C002
DENSITY 256K bits
PAGE CODE 6 bits
W551C005
512K bits

DENSITY 16M BITS
PAGE CODE 0 BITS
W551C240

Note: the W551C160/240/320 do not have a page code.
The first rising-edge signal in the ADDR clock resets the address shift registers. Once the address
data has been shifted into the address counter (and the page code bit[s] verified), the falling-edge of
the CLK clock increments the address counter. As a result, in serial-read mode, the ADDR and CLK
clocks should not be active simultaneously. This is illustrated in the timing diagram below.
