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), 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. The eight input
and output pins (IO
0
through IO
7
) are placed in a
high-impedance state when:
鈥?Deselected (CE HIGH)
鈥?Outputs are disabled (OE HIGH)
鈥?When the write operation is active (CE LOW, and WE LOW).
Write to the device by taking Chip Enable (CE) and Write
Enable (WE) inputs LOW. Data on the eight IO pins (IO
0
through IO
7
) is then written into the location specified on the
address pins (A
0
through A
16
).
Read from the device 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 appears on the IO pins.
