Functional Description
The CY7C1069BV33 is a high-performance CMOS Static
RAM organized as 2,097,152 words by 8 bits. Writing to the
device is accomplished by enabling the chip (by taking CE
LOW) and Write Enable (WE) inputs LOW.
Reading from the device is accomplished by enabling the chip
(CE LOW) as well as forcing the Output Enable (OE) LOW
while forcing the Write Enable (WE) HIGH. See the truth table
at the back of this data sheet for a complete description of
Read and Write modes.
The 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 CY7C1069BV33 is available in a 54-pin TSOP II package
with center power and ground (revolutionary) pinout.
