Functional Description
The CY7C168A is a high-performance CMOS static RAM or-
ganized as 4096 by 4 bits. Easy memory expansion is provided
by an active LOW Chip Enable (CE) and three-state drivers.
The CY7C168A has an automatic power-down feature, reduc-
ing the power consumption by 77% when deselected.
Writing to the device is accomplished when the Chip Select
(CE) and Write Enable (WE) inputs are both LOW. Data on the
four data input/output pins (I/O
memory location specified on the address pins (A
A
Reading the device is accomplished by taking the Chip Enable
(CE) LOW, while Write Enable (WE) remains HIGH. Under
these conditions, the contents of the location specified on the
address pins will appear on the four data input/output pins
(I/O
The input/output pins remain in a high-impedance state when
Chip Enable (CE) is HIGH or Write Enable (WE) is LOW.
A die coat is used to insure alpha immunity.
