HIGH), the 7C271/7C274 automatically powers down into a
low-power stand-by mode. The CY7C271 is packaged in the
300-mil slim package. The CY7C274 is packaged in the indus-
try standard 600-mil package. Both the 7C271 and 7C274 are
available in a cerDIP package equipped with an erasure win-
dow to provide for reprogrammability. When exposed to UV
light, the PROM is erased and can be reprogrammed. The
memory cells utilize proven EPROM floating gate technology
and byte-wide intelligent programming algorithms.
The CY7C271 and CY7C274 offer the advantage of lower
power, superior performance, and programming yield. The
EPROM cell requires only 12.5V for the super voltage, and low
current requirements allow for gang programming. The
EPROM cells allow each memory location to be tested 100%
because each location is written into, erased, and repeatedly
exercised prior to encapsulation. Each PROM is also tested for
AC performance to guarantee that after customer program-
ming, the product will meet DC and AC specification limits.
Reading the 7C271 is accomplished by placing active LOW
signals on CS
7C274 is accomplished by placing active LOW signals on OE and
