MSL27128K, -2
131, 072-BIT( 16384-WORD BY 8-BIT}
ERASABLE AND ELECTRICALLY REPROGRAMMABLE ROM
DESCRIPTION
The Mitsubishi M5L27128K is a high-speed 131072-bit
ultraviolet erasable and electrically reprogrammable read only
memory. It is suitable for microprocessor programming ap-
plications where rapid turn-around is required. The
M5L27128K is fabricated by N-channel double polysilicon gate
technology and is available in a 28-pin DIL package with a
transparent lid.
