The NM27C040 is a high performance, 4,194,304-bit Electrically Programmable UV Erasable Read Only Memory. It is organized as 512K words of 8 bits each. Its pin-compatibility with byte-wide JEDEC EPROMs enables upgrades through 8 Mbit EPROMs. The “Don’t Care” feature on VPP during read operations allows memory expansions from 1M to 8 Mbits with no printed cir.
s High performance CMOS — 120, 150ns access time
* s Simplified upgrade path —VPP is a “Don’t Care” during normal read operation s Manufacturer’s identification code s JEDEC standard pin configuration — 32-pin PDIP — 32-pin PLCC — 32-pin CERDIP
*Note: New revision meets 70ns. Please check with factory for availability.
