Functional Description
The CY7C291A is a high-performance 2K-word by 8-bit
CMOS PROM. It is packaged in a 300-mil ceramic package
which 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
programming algorithms.
The CY7C291A is a plug-in replacement for bipolar devices
and offers the advantage 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 perfor-
mance 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
CS
1
, and active HIGH signals on CS
2
and CS
3
. The contents
of the memory location addressed by the address line
(A
0

) will become available on the output lines (O
