Functional Description
The CY7C1019B/10191B 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/O
0
through I/O
7
) is then written into the location speci-
fied 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).
The CY7C1019B/10191B is available in standard 32-pin
TSOP Type II and 400-mil-wide SOJ packages. Customers
should use part number CY7C10191B when ordering parts
with 10 ns t
AA
, and CY7C1019B when ordering 12 and 15 ns
t
AA
.
