鈥?TTL-compatible I/O
鈥?Direct replacement for bipolar PROMs
鈥?Capable of withstanding >2001V static discharge
packages respectively. The CY7C281A is also available in a
28-pin leadless chip carrier. The memory cells utilize proven
EPROM floating-gate technology and byte-wide intelligent
programming algorithms.
The CY7C281A is a plug-in replacements for bipolar devices
and offer the advantages of lower power, superior perfor-
mance, and programming yield. The EPROM cell requires
only 12.5V for the super voltage, and low current requirements
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 encap-
sulation. Each PROM is also tested for AC performance 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
CS

and CS

, and active HIGH signals on CS
3
and CS

. The
contents of the memory location addressed by the address
lines (A

(O
