The Mitsubishi 740, also known as MELPS 740, is a series of 8-bit CMOS microcontrollers and microprocessors with an enhanced MOS Technology 6502 compatible core based on the expanded WDC 65C02. The ICs were manufactured by Mitsubishi Electric during the 1980s and 1990s. The 740 family was primarily intended for single-chip implementations, and included optional RAM and ROM or EPROM on-die. Other additions included a variety of optional timers, input/output lines, and many other features. It was estimated around 600 variations could be ordered.
