S0808U1X  
WCMS0808U1X  
32K x 8 Static RAM  
reducing the power consumption by over 99% when deselect-  
ed. The WCMS0808U1X is available in the 450-mil-wide  
(300-mil body width) narrow SOIC and TSOP.  
Features  
• Low voltage range:  
— 2.7V − 3.6V  
An active LOW write enable signal (WE) controls the writ-  
ing/reading operation of the memory. When CE and WE inputs  
are both LOW, data on the eight data input/output pins (I/O0  
through I/O7) is written into the memory location addressed by  
the address present on the address pins (A0 through A14).  
Reading the device is accomplished by selecting the device  
and enabling the outputs, CE and OE active LOW, while WE  
remains inactive or HIGH. Under these conditions, the con-  
tents of the location addressed by the information on address  
pins are present on the eight data input/output pins.  
• Low active power and standby power  
• Easy memory expansion with CE and OE features  
• TTL-compatible inputs and outputs  
• Automatic power-down when deselected  
• CMOS for optimum speed/power  
Functional Description  
The WCMS0808U1X is composed of a high-performance  
CMOS static RAM organized as 32K words by 8 bits. Easy  
memory expansion is provided by an active LOW chip enable  
(CE) and active LOW output enable (OE) and three-state driv-  
ers. These devices have an automatic power-down feature,  
The input/output pins remain in a high-impedance state unless  
the chip is selected, outputs are enabled, and write enable  
(WE) is HIGH.
