identical, but are packaged in 300-mil (7C291A, 7C293A) and
600-mil wide plastic and hermetic DIP packages (7C292A).
The CY7C293A has an automatic power down feature which
reduces the power consumption by over 70% when deselect-
ed. The 300-mil ceramic package may be equipped with an
erasure window; when exposed to UV light the PROM is
erased and can then be reprogrammed. The memory cells uti-
lize proven EPROM floating-gate technology and byte-wide in-
telligent programming algorithms.
The CY7C291A, CY7C292A, and CY7C293A are plug-in re-
placements for bipolar devices and offer the advantages of
lower power, reprogrammability, superior performance and
programming yield. The EPROM cell requires only 12.5V for
the supervoltage and low current requirements allow for gang
programming. The EPROM cells allow for each memory loca-
tion to be tested 100%, as each location is written into, erased,
and repeatedly exercised prior to encapsulation. Each PROM
is also tested for AC performance to guarantee that after cus-
tomer programming the product will meet DC and AC specifi-
cation limits.
A read is accomplished by placing an active LOW signal on
