Functional Description
[1]
The CY62126DV30 is a high-performance CMOS static RAM
organized as 64K 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 90% when addresses are not
toggling. The device can be put into standby mode reducing
power consumption by more than 99% when deselected (CE
HIGH). The input/output pins (I/O
0
through I/O
15
) are placed
in a high-impedance 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 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
(BLE) is LOW, then data from I/O pins (I/O
0
through I/O
7
), is
written into the location specified on the address pins (A
0
through A
15
). 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 address pins (A
0
through A
15
).
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/O
0
to I/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.
