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).
QP Semiconductor products are not authorized for use in any space applications. The inclusion of QP Semiconductor
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.
