8051-Based Microcontroller Third-Party Development Tools

Assemblers

Dallas Semiconductor microcontrollers execute the 8051 instruction set and are object-code-compatible with other 8051-based products. The special features of Dallas Semiconductor microcontrollers are accessed via Special Function Registers unique to our products, but the devices do not use any new instructions. These new Special Function Registers can be easily defined in the user's software with EQUATE statements or setup file. Once defined, the new Special Function Registers receive the same treatment as any of the original 8051 registers. This means that Dallas Semiconductor microcontrollers are compatible with every 8051-based software tool available.

An Intel Hex file format is required by devices that incorporate Bootstrap or ROM loaders. This is a standard output format for all 8051-compatible assemblers. In the rare case that an assembler cannot generate an Intel Hex file directly, a separate utility is included with the assembler.
