The MAX7378 contains two oscillators and a power-on reset circuit for microprocessors. The Speed input selects either 32.768 kHz (LF) or a higher frequency, which is pre-programmed. The type number ...

In our last session we looked at the basic structure and operation of a microcontroller (MCU). Now let’s look at some of the hardware (peripheral circuitry) required to support the microprocessor. In ...

It’s generally pretty easy to spot a microcontroller on a PCB. There are clues aplenty: the more-or-less central location, the nearby crystal oscillator, the maze of supporting passives, and perhaps ...
