provided by an active LOW chip enable (CE) and active LOW
output enable (OE) and three-state drivers. This device has an
automatic power-down feature, reducing the power consump-
tion by 81% when deselected. The CY7C199 is in the standard
300-mil-wide DIP, SOJ, and LCC packages.
An active LOW write enable signal (WE) controls the writ-
ing/reading operation of the memory. When CE and WE inputs
are both LOW, data on the eight data input/output pins (I/O

Reading the device is accomplished by selecting the device
and enabling the outputs, CE and OE active LOW, while WE
remains inactive or HIGH. Under these conditions, the con-
tents of the location addressed by the information on address
pins are present on the eight data input/output pins.
The input/output pins remain in a high-impedance state unless
the chip is selected, outputs are enabled, and write enable
(WE) is HIGH. A die coat is used to improve alpha immunity.
