Functional Description
The CY7C225A is a high-performance 512-word by 8-bit
electrically programmable read only memory packaged in a
slim 300-mil plastic or hermetic DIP, 28-pin leadless chip
carrier, and 28-pin PLCC. The memory cells utilize proven
EPROM floating gate technology and byte-wide intelligent
programming algorithms.
The CY7C225A replaces bipolar devices and offers the advan-
tages 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
after customer programming the product will meet AC specifi-
cation limits.
