MoBL  
CY62148V MoBL™  
512K x 8 MoBL Static RAM  
The device can be put into standby mode when deselected  
(CE HIGH).  
Features  
• Low voltage range:  
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-

Reading from the device is accomplished by taking Chip En-  
able (CE) and Output Enable (OE) LOW while forcing Write  
Enable (WE) HIGH. Under these conditions, the contents of  
the memory location specified by the address pins will appear  
on the I/O pins.  
• TTL-compatible inputs and outputs  
• Automatic power-down when deselected  
• CMOS for optimum speed/power

The CY62148V is a high-performance CMOS static RAM or-  
ganized as 524,288 words by 8 bits. This device features ad-  
vanced circuit design to provide ultra-low active current. This  
is ideal for providing More Battery Life™ (MoBL™) in portable  
applications such as cellular telephones. The device also has  
an automatic power-down feature that significantly reduces  
power consumption by 99% when addresses are not toggling.  
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).  
The CY62148V is available in a 36-ball FBGA, 32 pin TSOPII,  
and a 32-pin SOIC package.
