®
2-Mbit (256K x 8) MoBL Static RAM  
Features  
Functional Description[1]  
• Very high speed: 45 ns  
The CY62138EV30 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.  
— Wide voltage range: 2.20V – 3.60V  
• Pin-compatible with CY62138CV30  
• Ultra-low standby power  
®
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. The device can be put into  
standby mode reducing power consumption when deselected  
(CE HIGH).  
Typical standby current: 1 µA  
Maximum standby current: 7 µA  
Ultra-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  
— Typical active current: 2 mA @ f = 1 MHz  
• Easy memory expansion with CE and OE features  
• Automatic power-down when deselected  
• CMOS for optimum speed/power  
pins (I/O through I/O ) is then written into the location  
0
7
specified on the address pins (A through A ).  
0
18  
Reading from the device is accomplished by taking Chip  
Enable (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.  
• Offered in Pb-free 36-ball BGA package  
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).
