12-bit data acquisition circuits that have been developed to communicate with microprocessors over four wires are described.
12-bit data acquisition circuit
As board space and semiconductor package pins become more valuable, serial data transfer methods between microprocessors (MPUs) and their peripherals become more and more attractive. Not only does this save lines in the transmission medium, but, because of the savings in the package pins, more function can be packed into both the MPU and the peripheral. Users are increasingly able to take advantage of these savings as more MPU manufacturers ...
