features
device is accomplished by enabling the chip (by taking CE
1
LOW and CE
2
HIGH) and Write Enable (WE) inputs LOW.
Reading from the device is accomplished by enabling the chip
(CE
1
LOW and CE
2
HIGH) as well as forcing the Output
Enable (OE) LOW while forcing the Write Enable (WE) HIGH.
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
through I/O
7
) are placed in a
high-impedance state when the device is deselected (CE
1
HIGH or CE
2
LOW), the outputs are disabled (OE HIGH), or
during a Write operation (CE
1
LOW, CE
2
HIGH, and WE
LOW).
The CY7C1069AV33 is available in a 54-pin TSOP II package
with center power and ground (revolutionary) pinout, and a
48-ball fine-pitch ball grid array (FBGA) package.
Functional Description
