CY62256VN  
256K (32K x 8) Static RAM  
Features  
Functional Description  
■
Temperature Ranges  
The CY62256VN[1] family is composed of two high performance  
CMOS static RAM’s 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 tristate drivers.  
These devices have an automatic power down feature, reducing  
the power consumption by over 99% when deselected.

Commercial: 0°C to 70°C  
Industrial: –40°C to 85°C  
Automotive-A: –40°C to 85°C  
Automotive-E: –40°C to 125°C

Speed: 70 ns  
An active LOW write enable signal (WE) controls the  
writing/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 contents of the  
location addressed by the information on address pins are  
present on the eight data input/output pins.  
Low Voltage Range: 2.7V to 3.6V  
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 and Power  
The input/output pins remain in a high impedance state unless  
the chip is selected, outputs are enabled, and write enable (WE)  
is HIGH.  
Available in Standard Pb-free and non Pb-free 28-Pin (300-mil)  
Narrow SOIC, 28-Pin TSOP-I, and 28-Pin Reverse TSOP-I
