Functional Description[1]
The CY7C185 is a high-performance CMOS static RAM
organized as 8192 words by 8 bits. Easy memory expansion
is provided by an active LOW chip enable (CE1), an active
HIGH chip enable (CE2), and active LOW output enable (OE)
and
tri-state
drivers.
This
device
has
an
automatic
power-down feature (CE1 or CE2), reducing the power
consumption by 70% when deselected. The CY7C185 is in a
standard 300-mil-wide DIP, SOJ, or SOIC package.
An active LOW write enable signal (WE) controls the
writing/reading operation of the memory. When CE1 and WE
inputs are both LOW and CE2 is HIGH, 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 A12). Reading the device is accomplished by
selecting the device and enabling the outputs, CE1 and OE
active LOW, CE2 active HIGH, 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 insure alpha immunity.
