INFORMATION  
1M (64K x 16) Static RAM  
BLE are HIGH. The input/output pins (I/O0 through I/O15) are  
placed in a high-impedance state when: deselected Chip En-  
able 1 (CE1) HIGH or Chip Enable 2 (CE2) LOW, outputs are  
disabled (OE HIGH), both Byte High Enable and Byte Low  
Enable are disabled (BHE, BLE HIGH) or during a write oper-  
ation (Chip Enable 1 (CE1) LOW and Chip Enable 2 (CE2)  
HIGH and WE LOW).  
Features  
• Very high speed: 55 ns  
• Voltage range: 1.65V to 1.95V  
• Ultra-low active power  
— Typical active current: 0.5 mA @ f = 1 MHz  
— Typical active current: 2.5 mA @ f = fMAX  
• Ultra-low standby power  
• EasymemoryexpansionwithCE1, CE2 andOE features  
• Automatic power-down when deselected  
• CMOS for optimum speed/power  
Writing to the device is accomplished by taking Chip Enable 1  
(CE1) LOW and Chip Enable 2 (CE2) HIGH and Write Enable  
(WE) input 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).  
• Packages offered in a 48-ball FBGA and a 44-pin TSOP  
Type II  
Functional Description[1]  
Reading from the device is accomplished by taking Chip En-  
able 1 (CE1) LOW and Chip Enable 2 (CE2) HIGH 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 mem-  
ory 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.  
The CY62127DV18 is a high-performance CMOS static RAM  
organized as 64K words by 16 bits. This device features ad-  
vanced 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 by 99% when addresses are not toggling.  
The device can be put into standby mode reducing power con-  
sumption by more than 99% when deselected Chip Enable 1  
(CE1) HIGH or Chip Enable 2 (CE2) LOW or both BHE and
