W551CXXX
1. GENERAL DESCRIPTION
The W551Cxxx series is a serial voice memory IC designed to interface directly with Winbond
PowerSpeech, BandDirector, and ViewTalkfamily ICs to meet the increasing market demand
for longer playback duration. The W551Cxxx uses the same three-pin serial interface that Winbond
serial flash memory W55Fxx uses, which makes it easier to simulate and verify the memory contents
in advance. In addition, the W551Cxxx also provides a "Self-test mode" to verify the voice memory
contents easily and quickly, and some members of the W551Cxxx series allow W551Cxxx chips to be
“cascaded” to further lengthen playback duration.
W551Cxxx Serial Voice Memory is used to store pre-determined data. The following table shows the
part numbers in the W551Cxxx series and their respective memory density.

I/O DESCRIPTION
I Internal pull-high. Set TEST low to enable "Self-test" function.
TEST_OUT
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.
ADDR
Clock input for shift-in start address;
I
the first rising-edge signal resets the address counter.
DATA
IO Bi-directional data pin with internal pull-high.
CLK I Clock input for data read-out.
