Functional Description
[1]
The CY7C1021CV33 is a high-performance CMOS static
RAM organized as 65,536 words by 16 bits. This device has
an automatic power-down feature that significantly reduces
power consumption when deselected.
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
1
through I/O
8
), 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
9
through I/O
16
) 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
1
to I/O
8
. If Byte High Enable (BHE) is
LOW, then data from memory will appear on I/O
9
to I/O
16
. See
the truth table at the end of this data sheet for a complete
description of Read and Write modes.
The input/output pins (I/O
1
through I/O
16
) are placed in a
high-impedance state when the device is deselected (CE
HIGH), the outputs are disabled (OE HIGH), the BHE and BLE
are disabled (BHE, BLE HIGH), or during a Write operation
(CE LOW, and WE LOW).
The CY7C1021CV33 is available in 44-pin 400-Mil wide SOJ,
44-pin TSOP II and 48-ball FBGA packages.
