NM27C520 512K EPROM integrates an 8-bit address latch on the chip and fits into a single 20-pin, Small Outline Integrated Circuit package. The board-space requirement is reduced to about one-sixth of what is required for a standard 512K EPROM footprint, and a latch circuit eliminates the need for a second chip on board. Data sheets describe the product and its features. A functional product description and charts on programming and electrical characteristics are also included.
