CY62126EV30 MoBL  
1-Mbit (64K x 16) Static RAM  
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 significantly reduces power  
consumption when addresses are not toggling. Placing the  
device in standby mode reduces power consumption by more  
than 99 percent when deselected (CE HIGH). The input and  
output pins (I/O0 through I/O15) are placed in a high impedance  
state when the device is deselected (CE HIGH), the outputs are  
disabled (OE HIGH), both Byte High Enable and Byte Low  
Enable are disabled (BHE, BLE HIGH) or during a write  
operation (CE LOW and WE LOW).  
Features  
High speed: 45 ns  
Temperature ranges  
Industrial: –40 °C to +85 °C  
Automotive: –40 °C to +125 °C  
Wide voltage range: 2.2 V to 3.6 V  
Pin compatible with CY62126DV30  
Ultra low standby power  
Typical standby current: 1 A  
Maximum standby current: 4 A  
To write to the device, take Chip Enable (CE) and Write Enable  
(WE) inputs LOW. If Byte Low Enable (BLE) is LOW, then data  
from I/O pins (I/O0 through I/O7) is written into the location  
specified on the address pins (A0 through A15). If Byte High  
Enable (BHE) is LOW, then data from I/O pins (I/O8 through  
I/O15) is written into the location specified on the address pins  
(A0 through A15).  
Ultra low active power  
Typical active current: 1.3 mA at f = 1 MHz  
Easy memory expansion with CE and OE features  
Automatic power down when deselected  
To read from the device, take Chip Enable (CE) and Output  
Enable (OE) LOW while forcing the Write Enable (WE) HIGH. If  
Byte Low Enable (BLE) is LOW, then data from the memory  
location specified by the address pins appear on I/O0 to I/O7. If  
Byte High Enable (BHE) is LOW, then data from memory  
appears on I/O8 to I/O15. See the “Truth Table” on page 11 for a  
complete description of read and write modes.  
Complementary metal oxide semiconductor (CMOS) for  
optimum speed and power
