The M8051EW offers a complete, high performance 8051 core and development kit, based around Mentor Graphics’s highly successful M8051W implementation of this popular 8-bit microcontroller. While the standard part is designed around a 12-clock machine cycle, both the M8051W and the M8051EW use a two-clock machine cycle to facilitate particularly fast and/or low power embedded solutions whilst retaining functional compatibility with the industry standard part. It also features support for both up to 1 Mbyte of Program memory and up to 1 Mbyte of external Data Memory. The IP is supported by many 3rd-party C compilers and assemblers. For example, Mentor Graphics uses the C51 compiler from Keil Software for internal development and testing.
