CY7C1019CV33
128K x 8 Static RAM
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.
Features
• Pin and function compatible with CY7C1019BV33
• High speed
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).
— tAA = 8, 10, 12, 15 ns
• CMOS for optimum speed/power
• Data retention at 2.0V
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.
• Center power/ground pinout
• Automatic power-down when deselected
• Easy memory expansion with CE and OE options
• Available in 48-ball VFBGA, 32-pin TSOP II and 400-mil
SOJ package
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).
• Also available in lead-free 48-ball VFBGA and 32-pin
TSOP II packages
