• Ceramic Package: 32-Pin 400mil SOJ
• Compliant to SMD 5962-95600
is provided by an active LOW chip enable (CE), an active LOW
output enable (OE), and three-state drivers. Writing to the de-
vice is accomplished by taking chip enable (CE) and write en-
able (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 en-
able (CE) and output enable (OE) LOW while forcing write en-
able (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 5962-95600 is available in a standard 400-mil-wide 32-pin
ceramic SOJ package.
Functional Description
The 5962-95600 is a high-performance CMOS static RAM or-
ganized as 524,288 words by 8 bits. Easy memory expansion
