expansion is provided by an active LOW Chip Enable (CE), an
active LOW Output Enable (OE), and three-state drivers. Writ-
ing to the device is accomplished by taking Chip Enable (CE)
and Write Enable (WE) inputs LOW. Data on the four I/O pins
(I/O
0
through I/O
3
) is then written into the location specified on
the address pins (A
0
through A
19
).
Reading from the device is accomplished by taking Chip
Enable (CE) and Output Enable (OE) LOW while forcing Write
Enable (WE) HIGH. Under these conditions, the contents of
the memory location specified by the address pins will appear
on the I/O pins.
The four input/output pins (I/O
0
through I/O
3
) are placed in a
high-impedance state when the device is deselected (CE
HIGH), the outputs are disabled (OE HIGH), or during a write
operation (CE LOW, and WE LOW).
The CY7C1046BV33 is available in a standard 400-mil-wide
32-pin SOJ package with center power and ground (revolution-
ary) pinout.
