DESCRIPTION
The Mits.ubishi M5M27C12BK is a high-speed 131072-bit
ultraviolet erasable and electrically reprogram mabie read
only memory_ It is suitable for microprocessor program-
ming applications where rapid turn-around is required_
The M5M27C12BK is fabricated by N-channel double
polysilicon Memory gate and CMOS technology for periph-
eral circuits, and available in a 2B pin D I L package with a
transparent lid_
