CY7C199-15DMB - 32K x 8 Static RAM
Functional Description
The CY7C199 is a high-performance CMOS static RAM
organized as 32,768 words by 8 bits. Easy memory expansion
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
(I/O0 through I/O7) is written into the memory location
addressed by the address present on the address pins (A0
through A14). 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 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.
