Functional Description
The CY7C192 is a high performance CMOS static RAM
organized as 65,536 x 4 bits with separate IO. Easy memory
expansion is provided by active LOW Chip Enable (CE) and
tri-state drivers. It has an automatic power down feature that
reduces power consumption by 75% when deselected.
Writing to the device is accomplished when the Chip Enable (CE)
and write enable (WE) inputs are both LOW.
Data on the four input pins (I
0
through I
3
) is written into the
memory location specified on the address pins (A
0
through A
15
).
Reading the device is accomplished by taking the Chip Enable
(CE) LOW while the Write Enable (WE) remains HIGH. Under
these conditions, the contents of the memory location specified
on the address pins appears on the four data output pins.
The output pins stay in high impedance state when Write Enable
(WE) is LOW or Chip Enable (CE) is HIGH.
A die coat ensures alpha immunity.
