Data choices help compress 8051 code

Some people think that programs for microcontrollers like the 8051 that have limited program memory must be written in assembly language rather than a high-level language like C. The executable code ...

Expand your 8051 memory

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 ...

An efficient bit-banged SPI port for 8051-compatible microcontrollers

Although 8051-compatible microcontrollers with SPI ports are available, a lower-cost device with an SPI port bit-banged through GPIO pins often suffices. The code shown here takes advantage of ...

SST Sculpts Smallest 8051-Based MCU

Adding to the SuperFlash-based FlashFlex family of eight-bit, 8051-compatible microcontrollers, the SST89V54RD-33-C-QIF is available in a 6 mm x 6 mm x 0.8 mm WQFN package standing 0.7 mm in height, ...
