Functional Description
The CY7C1049BN is a high-performance CMOS static RAM
organized as 524,288 words by 8 bits. Easy memory expansion
is provided by an active LOW Chip Enable (CE), an active LOW
Output Enable (OE
), and three-state drivers. Writing to the
device is accomplished by taking Chip Enable (CE
) and Write
Enable (WE
) inputs LOW. Data on the eight I/O pins (I/O
0
through I/O
7
) is then written into the location specified on the
address pins (A
0
through A
18
).
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 eight input/output pins (I/O
0
through I/O
7
) 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 CY7C1049BN is available in a standard 400-mil-wide 36-pin
SOJ package with center power and ground (revolutionary)
pinout.
