Functional Description
The CY7C235A is a high-performance 1024 word by 8 bit elec-
trically programmable read only memory packaged in a slim
300-mil plastic or hermetic DIP, 28-pin leadless chip carrier, or
28-pin plastic leaded chip carrier. The memory cells utilize
proven EPROM floating gate technology and byte-wide intelli-
gent programming algorithms.
The CY7C235A replaces bipolar devices pin for pin and offers
the advantages of lower power, superior performance, and
high 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 the
product will meet AC specification limits after customer pro-
gramming.
