CY62146ESL MoBL®  
4-Mbit (256K × 16) Static RAM  
4-Mbit (256K  
× 16) Static RAM  
Features  
Functional Description  
Very high speed: 45 ns  
The CY62146ESL is a high performance CMOS static RAM  
organized as 256K words by 16 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  
when addresses are not toggling. Placing the device into standby  
mode reduces power consumption by more than 99% 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).  
Wide voltage range: 2.2 V to 3.6 V and 4.5 V to 5.5 V  
Ultra low standby power  
Typical Standby current: 1 A  
Maximum Standby current: 7 A  
Ultra low active power  
Typical active current: 2 mA at f = 1 MHz  
Easy memory expansion with CE and OE features  
Automatic power down when deselected  
Complementary metal oxide semiconductor (CMOS) for  
optimum speed and power  
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 A17). 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 A17).  
Available in Pb-free 44-pin thin small outline package (TSOP) II  
package  
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 appears 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.
