Functional Description
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 tri-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

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/O

HIGH), the outputs are disabled (OE HIGH), or during a write
operation (CE LOW, and WE LOW).
The CY7C1019CV33 is available in Standard 48-ball FBGA,
32-pin TSOP II and 400-mil-wide SOJ packages
