47V  
CY62147CV25/30/33  
MoBL™  
256K x 16 Static RAM  
cantly reduces power consumption by 80% when addresses  
are not toggling. The device can also be put into standby mode  
reducing power consumption by more than 99% when dese-  
lected (CE HIGH or both BLE and BHE are HIGH). The in-  
put/output pins (I/O0 through I/O15) are placed in a high-im-  
pedance state when: deselected (CE HIGH), outputs are  
disabled (OE HIGH), both Byte High Enable and Byte Low  
Enable are disabled (BHE, BLE HIGH), or during a write oper-  
ation (CE LOW and WE LOW).  
Features  
• High Speed  
— 55 ns and 70 ns availability  
• Voltage range:  
— CY62147CV25: 2.2V–2.7V  
— CY62147CV30: 2.7V–3.3V  
— CY62147CV33: 3.0V–3.6V  
Writing to the device is accomplished by taking 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).  
• Pin Compatible with CY62147V  
• Ultra-low active power  
— Typical active current: 1.5 mA @ f = 1 MHz  
— Typicalactivecurrent:5.5mA@f=fmax (70nsspeed)  
• Low standby power  
• Easy memory expansion with CE and OE features  
• Automatic power-down when deselected  
• CMOS for optimum speed/power  
Reading from the device is accomplished by taking 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 will appear on I/O0 to I/O7. If Byte High Enable (BHE) is  
LOW, then data from memory will appear on I/O8 to I/O15. See  
the truth table at the back of this data sheet for a complete  
description of read and write modes.  
Functional Description  
The CY62147CV25/30/33 are high-performance CMOS static  
RAMs organized as 256K words by 16 bits. These devices  
feature advanced circuit design to provide ultra-low active cur-  
rent. This is ideal for providing More Battery Life™ (MoBL™)  
in portable applications such as cellular telephones. The de-  
vices also have an automatic power-down feature that signifi-  
The CY62147CV25/30/33 are available in a 48-ball FBGA  
package.
