NM27C240 4,194,304-Bit (256k x 16) High Performance CMOS EPROM July 1998 NM27C240 4,194,304-Bit (256k x 16) High Performance CMOS EPROM General Description The NM27C240 is a high performance Electrically Programmable UV erasable ROM (EPROM). It contains 4,194,304 bits configured as 256k x 16 bits. It is offered in both erasable versions for prototyping and early production applications as well as nonerasable, plastic packaged versions that are ideal for high volume and automated assembly applications. The NM27C240 operates from a single 5V ±10% supply in the read mode. The NM27C240 is offered in both DIP and surface mount packages. The DIP package is a 40-pin dual-in-line ceramic with a quartz window to allow erasing. The surface mount package is a 44-pin PLCC that is offered in OTP.
