CY7C1019CV33
128K x 8 Static RAM
device has an automatic power-down feature that significantly
Features
reduces power consumption when deselected.
• Pin and function compatible with CY7C1019BV33
Writing to the device is accomplished by taking Chip Enable
•High speed (CE) and Write Enable (WE) inputs LOW. Data on the eight I/O
pins (I/O through I/O ) is then written into the location
0 7
—t = 10 ns
AA
specified on the address pins (A through A ).
0 16
• CMOS for optimum speed/power
