is 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
consumption 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
writing/reading operation of the memory. When CE and WE
inputs are both LOW, data on the eight data input/output pins

while WE remains inactive or HIGH. Under these conditions,
the contents 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.
