tical, but are packaged in 300-mil and 600-mil-wide packages
respectively. The CY7C281A is also available in a 28-pin lead-
less chip carrier. The memory cells utilize proven EPROM
floating-gate technology and byte-wide intelligent program-
ming algorithms.
The CY7C281A and CY7C282A are plug-in replacements for
bipolar devices and offer the advantages of lower power, su-
perior performance, and programming yield. The EPROM cell
requires only 12.5V for the super voltage, and low current re-
quirements allow for gang programming. The EPROM cells
allow each memory location to be tested 100% because 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.
Reading is accomplished by placing an active LOW signal on
