Functional Description
The CY7C1019D [1] is a high-performance CMOS static RAM
organized as 131,072 words by 8 bits. Easy memory expansion
is provided by an active LOW Chip Enable (CE), an active LOW
Output Enable (OE), and tri-state drivers. This device has an
automatic power-down feature that significantly reduces power
consumption when deselected. The eight input and output pins
(IO0 through IO7) are placed in a high-impedance state when:
Deselected (CE HIGH)
Outputs are disabled (OE HIGH)
When the write operation is active (CE LOW, and WE LOW).
Write to the device by taking Chip Enable (CE) and Write Enable
(WE) inputs LOW. Data on the eight IO pins (IO0 through IO7) is
then written into the location specified on the address pins (A0
through A16).
Read from the device 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 appears on the IO pins.
The CY7C1019D device is 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.
