Features
Functional Description
The CY62187EV30 is a high performance CMOS static RAM
organized as 4 M words by 16-bits. This device features
advanced circuit design to provide ultra low active current. It 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 percent when addresses are not toggling.
The device can also be put into standby mode when deselected
(CE
1
HIGH or CE
2
LOW or both BHE and BLE are HIGH). The
input and output pins (I/O
0
through I/O
15
) are placed in a high
impedance state when: deselected (CE
1
HIGH or 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 (CE
1
LOW, CE
2
HIGH and WE LOW).
To write to the device, take Chip Enables (CE
1
LOW and CE
2
HIGH) and Write Enable (WE) input 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
21
). 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
21
).
To read from the device, take Chip Enables (CE
1
LOW and CE
2
HIGH) 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 I/O
0
to I/O
7
. If Byte High Enable (BHE) is LOW, then data from
memory appears on I/O
8
to I/O
15
. See the
Truth Table
on page
9 for a complete description of read and write modes.
