Functional Description
[1]
The CY62147DV30 is a high-performance CMOS static RAM
organized as 256K words by 16 bits. This device features ad-
max
vanced circuit design to provide ultra-low active current. Thi s
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 also be put into standby
mode reducing power consumption by more than 99% when
deselected (CE
input/output pins (I/O

, BLE HIGH), or during a write operation (CE
LOW and WE LOW).
Writing to the device is accomplished by taking Chip Enable

) and Write Enable (WE) inputs LOW. If Byte Low Enable
) is LOW, then data from I/O pins (I/O0 through I/O7), is
(BLE
written into the location specified on the address pins (A
through A17). If Byte High Enable (BHE) is LOW, then data
from I/O pins (I/O
specified on the address pins (A
through I/O15) is written into the location
8
through A17).

Reading from the device is accomplished by taking Chip

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/O
the truth table at the back of this data sheet for a complete

description of read and write modes.
The CY62147DV30 is available in a 48-ball VFBGA, 44 Pin
