CY62138VN MoBL®  
256K x 8 Static RAM  
Features  
Functional Description  
• Temperature Ranges  
The CY62138VN is a high-performance CMOS static RAM  
organized as 256K words by 8 bits. This device features  
advanced 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 reduces power  
consumption by 99% when addresses are not toggling. The  
device can be put into standby mode when deselected (CS1  
HIGH or CS2 LOW). Writing to the device is accomplished by  
taking Chip Enable One (CS1) and Write Enable (WE) inputs  
LOW and Chip Enable Two (CS2) HIGH. Data on the eight I/O  
pins (I/O0 through I/O7) is then written into the location  
specified on the address pins (A0 through A17).Reading from  
the device is accomplished by taking Chip Enable One (CS1)  
and Output Enable (OE) LOW while forcing Write Enable (WE)  
and Chip Enable Two (CS2) HIGH. Under these conditions, the  
contents of the memory location specified by the address pins  
will appear on the I/O pins.The eight input/output pins (I/O0  
through I/O7) are placed in a high-impedance state when the  
device is deselected (CS1 HIGH or CS2 LOW), the outputs are  
disabled (OE HIGH), or during a write operation (CS1 LOW,  
CS2 HIGH, and WE LOW).  
— Industrial: –40°C to 85°C  
• Low voltage range:  
— 2.7–3.6V  
• Ultra-low active power  
• Low standby power  
• Easy memory expansion with CS1/CS2 and OE features  
• TTL-compatible inputs and outputs  
• Automatic power-down when deselected  
• CMOS for optimum speed/power  
• Offered in standard non-lead-free 36-ball FBGA
