鈥?Low active power
鈥?324 mW (max.)
鈥?2.0V data retention
鈥?Automatic power-down when deselected
鈥?TTL-compatible inputs and outputs

) is written into the location specified on the
address pins (A
0
鈥揂
17
).
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
鈥?I/O

. If Byte HIGH Enable (BHE) is
LOW, then data from memory will appear on I/O

to I/O
15
. See
the truth table at the back of this data sheet for a complete
description of Read and Write modes.
The input/output pins (I/O
0
鈥揑/O
15
) 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 CY7C1041CV33 is available in a standard 44-pin
400-mil-wide body width SOJ and 44-pin TSOP II package
with center power and ground (revolutionary) pinout, as well
as a 48-ball fine-pitch ball grid array (FBGA) package.
Functional Description
[1]
The CY7C1041CV33 is a high-performance CMOS Static
RAM organized as 262,144 words by 16 bits.
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
鈥揑/O
7
), is written
into the location specified on the address pins (A
