Features
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 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 reprogrammed. The memory cells utilize proven EPROM floating-gate technology and byte-wide intelligent programming algorithms.

Functional Description
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
CS1, and active HIGH signals on CS2 and CS3. The contents
of the memory location addressed by the address line (A0 −
A10) will become available on the output lines (O0 − O7).
The CY7C291A, CY7C292A, and CY7C293A are high-performance 2K-word by 8-bit CMOS PROMs. They are functionally

Erasure Characteristics
These PROMs need to be within 1 inch of the lamp during
erasure. Permanent damage may result if the PROM is exposed to high-intensity UV light for an extended period of time.
7258 Wsec/cm2 is the recommended maximum dosage.
Wavelengths 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
fluorescent lighting for extended periods of time.
Programming Information
The recommended dose of ultraviolet light for erasure is a
wavelength of 2537 Angstroms for a minimum dose (UV intensity 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 minutes.
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 packages, please see the PROM Programming Information located
at the end of this section. Programming algorithms can be obtained from any Cypress representative.
