Suppose for a moment that you're an engineer designing a new 8051-based product. Not unexpectedly, the application's code size will greatly exceed the 64KB architectural limit of the 8051's program ...

Now the manufacturing end of the 8051-based product cycle is facilitated through universal, high-performance, stand-alone in-system programmers from SMH Technologies. These quickly and reliably load ...

[Andrew] picked up a handful of these big STC 8051 chips for a song and dance. The problem he has with them is the clunky VB6 programming software that only wants to run on a Windows box. He ...

The DS89C4x0 single-cycle 8051 processors come with flash memories up to 64 kbytes. They can be programmed by an application. The devices also include two full-duplex UARTs, 13 interrupt sources ...

He just found these fabulous little chips in a component drawer and decided it was time to figure these guys out. Eventually, [Matt] stumbled across this awesome resource for 8051 programming.

Taiwanese chip maker Nuvoton Technology has announced a 24MHz 8051-style series of MCUs for industrial automation, motor control, LED dimming and home appliances.
