Functional Description
The CY7C167A is a high-performance CMOS static RAM or-
ganized as 16,384 words by 1 bit. Easy memory expansion is
provided by an active LOW Chip Enable (CE) and three-state
drivers. The CY7C167A has an automatic power-down fea-
ture, reducing the power consumption by 67% when
deselected.
Writing to the device is accomplished when the Chip Select
(CE) and Write Enable (WE) inputs are both LOW. Data on the
input pin (DI) is written into the memory location specified on
the address pins (A
Reading the device is accomplished by taking the Chip Enable
(CE) LOW, while (WE) remains HIGH. Under these conditions,
the contents of the location specified on the address pins will
appear on the data output (DO) pin.
The output pin remains in a high-impedance state when Chip
Enable is HIGH, or Write Enable (WE) is LOW.
A die coat is used to insure alpha immunity.
