W551Cxxx Data Sheet  
General Description  
The W551Cxxx series is designated to interface with Winbond PowerSpeech , BandDirector , and  
ViewTalk family ICs directly. Application with PowerSpeech , BandDirector , and ViewTalk the serial voice  
memory W551Cxxx can lengthen the playback duration to meet the increasing market demand on complicated scenarios.  
The W551Cxxx was already utilized the same serial interface as Winbond serial flash memory W55Fxx for designer to  
simulate & verify the memory contents in advance. Besides that, W551Cxxx also provides a "Self-test mode" to verify  
the voice memory contents easily and quickly.  
1.1 W551Cxxx Product Selection Guide  
W551Cxxx Serial Voice Memory is used to store pre-determined data. To communicate with W551Cxxx in  
serial data mode, the connection interface total pin counts can be reduced to three pins only. The following table is  
shown the product selection guide of part number vs. memory density.

Function Description  
3.1 W551Cxxx Functional Description  
The maximum number of the ADDR clock is 24 bits. The address data is shifted into the 24 bits address counter  
by the ADDR clock. The MSB x bits of the address counter are the page codes, and the rest (24 - x) bits are the bit  
of address. Note that the MSB is shifted first. The MSB 5 bits of the address counter are always gating (exclusive  
OR) with the content of the page-code cells to determine whether these two articles are match or not. Only when the  
page codes are matched with the content of the page-code cells, this device can be enabled. The counting source of  
the address counter is the CLK clock, the falling edge signal of the CLK clock up-count the counter.  
In normal-read mode the ADDR and CLK clock cannot be active simultaneously. The first rising edge signal of  
the ADDR clock after CLK clocking will reset the address shift registers. The following table describes the needed  
bits of page code:

3.2 W551Cxxx Normal Read Mode  
This chip can also be connected with Winbond PowerSpeech , BandDirector , and ViewTalkTM series  
directly. Because in power-on condition, the default function mode is the normal read mode, then the mode selected  
procedure can be skipped.

3.3 W551Cxxx Self-test Mode  
In normal read mode, the TEST pin is internally pulled high, and the TEST_OUT pin is in logic ' 1 ' state.  
When the TEST pin is pulled low, the W551Cxxx enters the "self-test mode". In this mode, the self-test process is  
started at the falling edge of the TEST signal. The self-test process accumulates each byte (8 bit) of voice memory  
content from address 00000h to 7FFFFh. If the accumulated result is 00h, a logic ' 0 ' will be output from  
TEST_OUT pin. Or else, a logic ' 1 ' signal will be output from TEST_OUT pin.
