COMPILERS AND SOFTWARE DEVELOPMENT
We recommend both the IAR Systems and the Keil 8051 C-compilers for software development. Each corporation has supported our products for many years with an optimizing C-compiler that delivers cycle-efficient and predictable results.
IAR Embedded Workbench for 8051 has been used by a number of our customers. It produces excellent results in terms of both code density and cycle efficiency.
The Keil C51 C-compiler, and uVision integrated development IDE, support all our products. In particular the 16-bit pointer extensions to the M8051W and M8051EW are used during compiler optimization to produce more efficient code and run times.
The M8051EW debug interface is fully compatible with FS2 debugger solutions which provide a PC based software debug environment and JTAG interface cable. The M8051EW is designed to support a rich set of debug functions including run, stop, break, hardware and software breakpoints and triggers, instruction traceback and full debugger read/write access to all 8051 memory spaces and registers. The debug interface is a four-wire JTAG-compliant interface.
All our designs are 100% binary and cycle compatible with Intel's MCS-51 family of microcontrollers. Many data sheet archive sites continue to provide the original Intel MCS-51 documentation.
