Welcome to part three of “Interrupts: The Good, the Bad, and the Ugly”. We’ve already professed our love for interrupts, showing how they are useful for solving multiple common microcontroller tasks ...

Edge-triggered interrupts are useful in microcontroller (MCU) applications for processing asynchronous events like switch closures, level transitions, and pulses. However, low-cost MCUs offer limited ...

Austin, Texas — The new TK80C51FA microcontroller from Tekmos Inc. is designed as a replacement for ROMless 8051 series microcontrollers that have been obsoleted by other vendors. It is a pin-for-pin, ...

Boasting of a 50x performance gain over original 8051 microcontrollers and a six-fold gain over the next-fastest 8051s, the DS89C420 is said to be the first 8051-compatible controller to achieve peak ...
