CY7C1019B
128K x 8 Static RAM
Features
鈥?High speed
鈥?t
AA
= 12 ns
鈥?CMOS for optimum speed/power
鈥?Center power/ground pinout
鈥?Automatic power-down when deselected
鈥?Easy memory expansion with CE and OE options
鈥?Functionally equivalent to CY7C1019
鈥?Available in Pb-free and non Pb-free 32-pin TSOP II, non
Pb-free 400-mil-wide SOJ packages.
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
pins (I/O
0
through I/O
7
) is then written into the location
specified on the address pins (A
0
through A
16
).
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
0
through I/O
7
) 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).
Functional Description
The CY7C1019B is a high-performance CMOS static RAM
organized as 131,072 words by 8 bits. Easy memory
