Functional Description
[1]
The CY62146EV30 is a high performance CMOS static RAM
organized as 256K 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 80% when addresses are not
toggling. The device can also be put into standby mode
reducing power consumption by more than 99% when
deselected (CE HIGH). The input and output pins (IO
0
through
IO
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)
Write operation is active (CE LOW and WE LOW)
Write to the device by taking Chip Enable (CE) and Write
Enable (WE) inputs LOW. If Byte Low Enable (BLE) is LOW,
then data from IO pins (IO
0
through IO
7
), is written into the
location specified on the address pins (A
0
through A
17
). If Byte
High Enable (BHE) is LOW, then data from IO pins (IO
8
through IO
15
) is written into the location specified on the
address pins (A
0
through A
17
).
Read from the device 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 appear on IO
0
to IO
7
. If
Byte High Enable (BHE) is LOW, then data from memory
appears on IO
8
to IO
15
. See the
“Truth Table” on page 9
for a
complete description of read and write modes.
