Functional Description
The CY7C1034DV33 is a high performance CMOS static RAM
organized as 256K words by 24 bits. This device has an
automatic power down feature that significantly reduces power
consumption when deselected.
To write to the device, enable the chip (CE
1
LOW, CE
2
HIGH,
and CE
3
LOW) while forcing the Write Enable (WE) input LOW.
To read from the device, enable the chip by taking CE
1
LOW, CE
2
HIGH, and CE
3
LOW, while forcing the Output Enable (OE) LOW
and the Write Enable (WE) HIGH. See the
7 for a complete description of Read and Write modes.
The 24 IO pins (IO
0
to IO
23
) are placed in a high impedance state
when the device is deselected (CE
1
HIGH, CE
2
LOW, or CE
3
HIGH) or when the output enable (OE) is HIGH during a write
operation. (CE
1
LOW, CE
2
HIGH, CE
3
LOW, and WE LOW).
