Functional Description
[1]
The CY7C1019D 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 active LOW Output Enable (OE
), and tri-state drivers. This
), an
device has an automatic power-down feature that significantly reduces power consumption when deselected. The eight input and output pins (IO
through IO7) are placed in a
0
high-impedance state when:
• Deselected (CE HIGH)
• Outputs are disabled (OE
• When the write operation is active (CE

) and Write
through IO7) is then written into the location specified on the address pins (A
through A16).

Read from the device by taking Chi p En ab l e (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 appears on the IO pins.
