Functional Description
[1]
The CY7C109D/CY7C1009D 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
1
), an active HIGH Chip Enable (CE
2
), an active LOW
Output Enable (OE), and tri-state drivers.The eight input and
output pins (IO
0
through IO
7
) are placed in a high-impedance
state when:
Deselected (CE
1
HIGH or CE
2
LOW),
Outputs are disabled (OE HIGH),
When the write operation is active (CE
1
LOW, CE
2
HIGH,
and WE LOW)
Write to the device by taking Chip Enable One (CE
1
) and Write
Enable (WE) inputs LOW and Chip Enable Two (CE
2
) input
HIGH. 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 One (CE
1
) and
Output Enable (OE) LOW while forcing Write Enable (WE) and
Chip Enable Two (CE
2
) HIGH. Under these conditions, the
contents of the memory location specified by the address pins
appears on the IO pins.
