PRELIMINARY  
CY62256V  
32K x 8 Static RAM  
ers. These devices have an automatic power-down feature,  
reducing the power consumption by over 99% when deselect-  
ed. The CY62256V family is available in the standard  
450-mil-wide (300-mil body width) SOIC, TSOP, and reverse  
TSOP packages.  
Features  
• Low voltage range:  
2.7V 3.6V (62256V)  
2.3V 2.7V (62256V25)  
An active LOW write enable signal (WE) controls the writ-  
ing/reading operation of the memory. When CE and WE inputs  
1.6V 2.0V (62256V18)  
• 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  
are both LOW, data on the eight data input/output pins (I/O  
0
through I/O ) is written into the memory location addressed by  
7
the address present on the address pins (A through A ).

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.  
Functional Description  
The input/output pins remain in a high-impedance state unless  
the chip is selected, outputs are enabled, and write enable  
(WE) is HIGH.  
The CY62256V family is composed of three high-performance  
CMOS static RAM’s organized as 32,768 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-
