General Description
The QP7C291A, and QP7C292A are high-performance 2K-word by 8-bit CMOS PROMs. They are functionally
identical, but are packaged in 300-mil (QP7C291A) and 600-mil wide plastic and hermetic DIP packages
(QP7C292A). The QP7C291A is also available in LCC/PLCC packages.
The devices are available in windowed packages (Erasable when exposed to UV light) and can be
reprogrammed. They are also available in non-windowed OTP (One-Time-Programmable) hermetic and plastic
packages.
The memory cells utilize proven EPROM floating-gate technology and byte-wide intelligent programming
algorithms.
The QP7C291A, and QP7C292A, are plug-in replacements for Cypress PROMs. They are also designed to be
plug-in replacements for bipolar devices and offer the advantages of lower power, re-programmability, 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 exercised prior to packaging. Each PROM is 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).

products in space applications implies that the space application manufacturer assumes all risk of such use and in doing
so indemnifies QP Semiconductor against all charges.

Erasure Characteristics:
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.
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. 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.
Programming Information:
The QP7C291A and QP7C292A program using the same programming algorithm as Cypress 7C291A
and 7C292A devices. A variety of programming equipment currently supports the Cypress
Algorithm. QP Semiconductor has verified that the devices program on Data I/O Unisite and on a
programmer supplied by EETools.
