Extending the company's FRAM-enhanced microcontroller offerings, the VRS51L3174 debuts as an 8051-based MCU with 8 KB of nonvolatile FRAM that drops into industry-standard 44-pin QFP sockets. Features ...
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 ...
