About 8051 Disassembler

A Windows desktop tool for making sense of compiled 8051 firmware. Open an Intel HEX file and it
reconstructs the assembly listing, resolves jump and call targets, and shows how the code is laid
out in memory, so firmware you have only as a HEX dump becomes something you can actually read.

Built for the Intel 8051 family and its derivatives, and free to use.
