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 ...

What’s the biggest difference between writing code for your big computer and a microcontroller? OK, the memory and limited resources, sure. But we were thinking more about the need to directly ...

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 ...

Woodcliff Lake, NJ, January 28, 2014 -- An 8051-compatible microcontroller core with 26.85 times the performance per MHz of the original 8051 chip is now available from semiconductor intellectual ...

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 ...
