PRELIMINARY  
CY62148V  
512K x 8 Static RAM  
an automatic power-down feature that reduces power con-  
sumption by more than 99% when deselected.  
Features  
• 2.7V3.6V operation  
• CMOS for optimum speed/power  
• Low active power  
Writing to the device is accomplished by taking chip enable  
(CE) and write enable (WE) inputs LOW. Data on the eight I/O  
pins (I/O through I/O ) is then written into the location speci-  
0
7
fied on the address pins (A through A ).  
0
18  
— 180 mW (max.)  
Reading from the device is accomplished by taking chip en-  
able (CE) and output enable (OE) LOW while forcing write en-  
able (WE) HIGH for read. Under these conditions, the contents  
of the memory location specified by the address pins will ap-  
pear on the I/O pins.  
• Low standby power (Commercial LL version)  
— 54 µW (max.)  
• Automatic power-down when deselected  
• TTL-compatible inputs and outputs  
• Easy memory expansion with CE and OE options  
The eight input/output pins (I/O through I/O ) are placed in a  
0
7
high-impedance state when the device is deselected (CE  
HIGH), the outputs are disabled (OE HIGH), or during a write  
operation (CE LOW, and WE LOW).  
Functional Description  
The CY62148V is a high-performance CMOS static RAM or-  
ganized as 524,288 words by 8 bits. Easy memory expansion  
is provided by an active LOW chip enable (CE), an active LOW  
output enable (OE), and three-state drivers. This device has  
The CY62148V is available in a standard 32 pin 450-mil-wide  
body width SOIC and 32 pin TSOPII packages.
