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 ...
A while back, [Matt] bought a few 8051 MCUs and tucked them away for a future project. He just found these fabulous little chips in a component drawer and decided it was time to figure these guys out.
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 with ...
