Many microprocessor-based products require a manual-reset capability that allows the user, test technician, or external circuitry to reboot the system without a full power-down/power-up cycle. To ...

The programmable logic controller (PLC) is a microprocessor-based system that accepts input data from switches and sensors, processes that data by making decisions in accordance with a stored program, ...

When the microprocessor and inexpensive ROM memory arrived in the early 1970s, building small, stored-program computing systems became practical. System designers learned that with the rapidly growing ...

Increment and decrement. They sound like simple functions. But even the simplest functions can get quite complex in a microprocessor design. Ken Shirriff has written up a great blog post about his ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

Forty years ago today, electronics and semiconductor trade newspaper Electronic News ran an advertisement for a new kind of chip. The Intel 4004, a $60 chip in a 16-pin dual in-line package, was an ...
