Online Assembler for 8051 Microcontrollers
Click here to Assemble your 8051 microcontroller based programs online.
Just upload the Assembly file and download the Hex file and the List file for your assembly program.
General 8051 Assembler
The 8051 Cross Assembler takes an assembly language source file created with a text editor and translates it into a machine language object file. This translation process is done in two passes over the source file. During the first pass, the Cross Assembler builds a symbol table from the symbols and labels used in the source file. It's during the second pass that the Cross Assembler actually translates the source file into the machine language object file. It is also during the second pass that the listing is generated.

Free 8051 Microcontroller IDE for Linux
If you are using Linux and want a free IDE for your 8051 microcontroller, then you can use this. MCU 8051 IDE is integrated development environment for microcontrollers based on 8051. This IDE supports assembly and C languages programs. It has its own Assembler and C complier. SDCC is used as the C compiler.
This IDE contains simulator, source code editor, assembler, HW programmer and much other tools. Simulator supports over 79 MCU primarily from Atmel
HW programmer supports 8 ISP programmable MCUs from Atmel (AT89Sxx, AT89LSxx).
There is also support for simple hardware simulation (like LEDs, keys, etc.).
