Functional Description
The CY7C1018DV33/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 CY7C1018DV33/CY7C1019DV33 are available in Pb-free
32-pin 400-Mil wide Molded SOJ, 32-pin TSOP II and 48-ball
VFBGA packages.
