Functional Description
[1]
The CY62167DV18 is a high-performance CMOS static RAM
organized as 1024K 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 significantly
reduces power consumption by 99% when addresses are not
toggling. The device can be put into standby mode reducing
power consumption by more than 99% when deselected Chip
Enable 1 (CE
1
) HIGH or Chip Enable 2 (CE
2
) LOW or both
BHE and BLE are HIGH. The input/output pins (I/O
0
through
I/O
15
) are placed in a high-impedance state when: deselected
Chip Enable 1 (CE
1
) HIGH or Chip Enable 2 (CE
2
) LOW,
outputs are disabled (OE HIGH), both Byte High Enable and
Byte Low Enable are disabled (BHE, BLE HIGH) or during a
write operation (Chip Enable 1 (CE
1
) LOW and Chip Enable 2
(CE
2
) HIGH and WE LOW).
Writing to the device is accomplished by taking Chip Enable 1
(CE
1
) LOW and Chip Enable 2 (CE
2
) HIGH and Write Enable
(WE) input LOW. If Byte Low Enable (BLE) is LOW, then das
pins (A
0
through A
19
). If Byte High Enable (BHE) is LOW, then
data from I/O pins (I/O
8
through I/O
15
) is written into the
location specified on the ad
Reading from the device is accomplished by taking Chip
Enable 1 (CE
1
) LOW and Chip Enable 2 (CE
2
) HIGH and
Output Enable (OE) LOW while forcing the Write Enable (WE)
HIGH. If Byte Low Enable (<>O
7
. If Byte High Enable (BHE)
is LOW, then data from memory will appear on I/O
8
to I/O
15
.
See the truth table at the back of this data sheet for a complete
description of read and write modes.
