Functional Description
The CY7C1019DV33 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 three-state 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).
The CY7C1019DV33 is available in Pb-free 32-pin 400-Mil wide
Molded SOJ, 32-pin TSOP II and 48-ball VFBGA packages.
