Functional Description[1]
The CY62128BN is a high-performance CMOS static RAM
organized as 128K words by 8 bits. Easy memory expansion
is provided by an active LOW Chip Enable (CE1), an active
HIGH Chip Enable (CE2), an active LOW Output Enable (OE),
and tri-state drivers. This device has an automatic
power-down feature that reduces power consumption by more
than 75% when deselected.
Writing to the device is accomplished by taking Chip Enable
One (CE1) and Write Enable (WE) inputs LOW and Chip
Enable Two (CE2) input HIGH. Data on the eight I/O pins (I/O0
through I/O7) is then written into the location specified on the
address pins (A0 through A16).
Reading from the device is accomplished by taking Chip
Enable One (CE1) and Output Enable (OE) LOW while forcing
Write Enable (WE) and Chip Enable Two (CE2) 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/O0 through I/O7) are placed in a
high-impedance state when the device is deselected (CE1
HIGH or CE2 LOW), the outputs are disabled (OE HIGH), or
during a write operation (CE1 LOW, CE2 HIGH, and WE LOW).
