General Description
CY7C225A General 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 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 after customer programming the product will meet AC specification limits.
