Functional Description
CY7C292A/CY7C293A
2K x 8 Reprogrammable PROM
identical, bu t are pac ka ged in 300 -mil (7C29 1A, 7C293A) an d
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 deselected. 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 reprogr ammed. The memo ry cells utilize prov en EPR OM floatin g-gate techno log y and b yte-wide intelligent programming algorithms.
The CY7C291A, CY7C292A, and CY7C293A are plug-in replacements 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 location 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 customer programming the product will meet DC and AC specification limits.
A read is accomplished by placing an active LOW signal on
, and active HIGH signals on CS2 and CS3. The contents
CS
1
of the memory location addressed by the address line (A
) will become available on the output lines (O0 − O7).

placed ov er the wi ndow if the PROM is e xp os ed to sunlight or
fluorescent lighting for extended periods of time.
The recommended dose of ultraviolet light for erasure is a
wav elength of 2537 Angstroms f or a minimum dose (UV intensity x exposure time) of 25 Wsec/cm2. For an ultraviolet lamp
with a 12 mW/cm

power rating, the exposur e time woul d be
approximately 35 minutes.
