Mentor Graphics 
Short Desc. : M8051EW Fast 8-bit Microcontroller with On-Chip Debug
Overview :

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.

Features : - • Two clocks per machine cycle architecture
- • JTAG Interface and software for debug
- • Up to 1 Mbyte of external Data Memory, accessible by a choice of interfaces
- • Up to 256 bytes of Internal Data Memory
- • Up to 1 Mbyte of RAM or ROM Program Memory, accessible by a choice of interfaces
- • Support for synchronous and asynchronous Program, External Data & Internal Data Memory
- • Wait states support for slow Program and External Data Memory
- • Software compatible with Intel 8051, 8031, 87C51 and 8052 equivalents
- • 2 or 3 16-bit timer/counters (optional)
- • Full-duplex serial port (optional)
- • Intel-compatible I/O ports
- • Max 25 source, 2 or 4-level interrupt controller; choice of handling scheme
- • Option of 1, 2, 4 or 8 data pointers
- • Support for user-defined SFRs
- • Separate demultiplexed memory interface ports
- • Fully synthesizable
- • Scan test ready
