Function al Des cription
The CY7C291A, CY7C292A, and CY7C29 3A are high -perfor-
manc e 2K-word by 8-bit CMOS PROMs. They are functionally
identical, but are packag ed in 300-mil (7C29 1A, 7C293 A) and
600-mil wide plastic and hermetic DIP packages (7C292A).
The CY7C293A has an automatic power down featur e which
reduces the power consumpti o n by ov er 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 programmi ng algorithm s.
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
program ming. The EPROM cells allow for each memory loca-
tion to be tested 100%, as each loc ation is written into, erased ,
and repeatedly exercised prior to encapsulation. Each PROM
is also tested for AC performance to gu aran tee that after cus-
tomer programming the product will meet DC and AC specifi-
cation limi ts.
A read is accomplished by placing an active LOW signal on
CS1, and active HIGH signals on CS2 and C S3. The contents
of the memory location addressed by the address line (A0 −
A10) will b ecome available on the output lines ( O0 − O7).

Erasure Characteristics
W avelengths of light less than 4000 Angstroms begin to erase
these PROMs. For this reason, an opaque label should be
placed over the window if the PROM is exposed to sunlight or
fluorescen t lighting for extended periods of time.
The recommended dose of ultraviolet light for erasure is a
wavelength of 2537 Angstroms for a minimum dose (UV inten-
sity x exposure time) of 25 Wsec/cm2. For an ultraviolet lamp
with a 12 mW/cm2 power rating, the exposure time would be
approximately 35 min utes.
These PROMs need to be within 1 inch of the lamp during
erasure. Permanent damage may result if the PROM is ex-
pose d to high-intensity UV light for an extended period of time.
7258 Wsec/cm2 is the recommended maximum dosage.
Pro g ramm in g Inform at ion
Programming support is available from Cypress as well as
from a number of third-party software vendors. For detailed
programming information, including a listing of software pack-
ages, please see the PROM Programming Information located

tained from any Cypress representative.
