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 pedance state when: deselected (CE abled (OE are disabled (BHE

HIGH), both Byte High Enable and Byte Low Enable
, BLE HIGH), or during a write operation (CE
LOW and WE LOW). Writing to the device is accomplished by taking Chip Enable
(CE
) 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 Enable (CE Write Enable (WE
) and Output Enable (OE) LOW while forcing the

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

Notes:
2. NC pins are not internally connected on the die.
3. DNU pins have to be left floating or tied to V
4. Pins H1, G2, and H6 in the VFBGA package are address expansion pins for 8 Mb, 16 Mb, and 32 Mb, respectively.
5. Typical values are included for reference only and are not guaranteed or tested. Typical values are measured at V
to ensure proper application.
