Voltage comparators began appearing in single-chip microcontrollers (MCUs) in the late 1990s. At the time, the change was viewed as a simple cost reduction. Comparators required less silicon, while ...

implements the integrator function of the sigma-delta function with an external capacitor, C INT. When you set RA3 of the 8-bit microcontroller high, the voltage at V CINT increases. This situation ...

Analog-to-digital converters (ADCs) are used in a wide range of electronic devices. However, most of the low-cost microcontrollers do not include an ADC peripheral. This design idea provides a way to ...

It never fails — we post a somewhat simple project using a microcontroller and someone points out that it could have been accomplished better with a 555 timer or discrete transistors or even a couple ...

There was a time when microprocessors were slow and expensive devices that needed piles of support chips to run, so engineers came up with ingenious tricks using extra hardware preprocessing inputs to ...

In the previous two installments, we examined the first batch of core independent peripherals, including the Configurable Logic Cell (CLC), the Signal Measurement Timer (SMT), the Numerically ...
