Functional Description
The CY7C107D [1] and CY7C1007D [1] are high-performance
CMOS static RAMs organized as 1,048,576 words by 1 bit. Easy
memory expansion is provided by an active LOW Chip Enable
(CE) and tri-state drivers. These devices have an automatic
power-down feature that reduces power consumption by more
than 65% when deselected. The output pin (DOUT) is placed in a
high-impedance state when:
Deselected (CE HIGH)
When the write operation is active (CE and WE LOW)
Write to the device by taking Chip Enable (CE) and Write Enable
(WE) inputs LOW. Data on the input pin (DIN) is written into the
memory location specified on the address pins (A0 through A19).
Read from the device by taking Chip Enable (CE) LOW while
while forcing Write Enable (WE) HIGH. Under these conditions,
the contents of the memory location specified by the address
pins appears on the data output (DOUT) pin.
The CY7C107D and CY7C1007D devices are suitable for
interfacing with processors that have TTL I/P levels. It is not
suitable for processors that require CMOS I/P levels. Please see
Electrical Characteristics on page 4 for more details and
suggested alternatives.
