General Description
CY7C167A General Description
The CY7C167A is a high-performance CMOS static RAM organized 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 feature, 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 (A0 through A13).
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.
