The CY7C1019CV33 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 tristate drivers. This device has an
automatic power down feature that significantly reduces power
consumption when deselected.
Writing to the device is accomplished by taking Chip Enable (CE)
and Write Enable (WE) inputs LOW. 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
(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 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 (CE HIGH),
the outputs are disabled (OE HIGH), or during a write operation
(CE LOW, and WE LOW).

5. 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.
6. tHZOE, tHZCE, and tHZWE are specified with a load capacitance of 5 pF as in part (d) of Figure 2 on page 5. Transition is measured 500 mV from steady-state voltage.
7. 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.
8. This parameter is guaranteed by design and is not tested.
9. 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 setup and hold timing should be referenced to the leading edge of the signal that terminates the write.
10. The minimum write cycle time for Write Cycle no. 3 (WE controlled, OE LOW) is the sum of tHZWE and tSD.
