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.

Notes
8. Test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5 V, input pulse levels of 0 to 3.0 V, and output loading of the specified IOL/IOH
and 30-pF load capacitance.
9. tPOWER gives the minimum amount of time that the power supply should be at typical VCC values until the first memory access can be performed.
10. tHZOE, tHZCE, and tHZWE are specified with a load capacitance of 5 pF as in (c) of Figure 2 on page 5. Transition is measured when the outputs enter a high impedance state.
11. At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any given device.
12. This parameter is guaranteed by design and is not tested.
13. The internal write time of the memory is defined by the overlap of CE LOW and WE LOW. CE and WE must be LOW to initiate a write, and the transition of any of these
signals can terminate the write. The input data set-up and hold timing should be referenced to the leading edge of the signal that terminates the write.
14. The minimum write cycle time for Write Cycle no. 3 (WE controlled, OE LOW) is the sum of tHZWE and tSD.
