Counter/timer hardware is a crucial component of most embedded systems. In some cases a timer is needed to measure elapsed time; in others we want to count or time some external events. Here's a ...

The major component of this circuit is Microchip’s SST89E54RDA-40-C-PIE, which is a pin-for-pin compatible with typical 8051 microcontroller devices. It has a built-in timer used to produce accurate ...

In this paper the authors give a novel idea about the design and implementation of a microcontroller based pulse counter. Intel 8051 is used as the main microcontroller unit and the system has been ...

Many embedded-microcontroller applications require generation of analog signals. An integrated or stand-alone DAC fills the role. However, you can often use PWM signals for generating the required ...

Most digital timers require a set of dip switches or rotary BCD encoders to preset their interval. But those techniques consume eight or more inputs from a microcontroller's (MCU's) I/O lines. To ...

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 ...

Embedded World — Nuremburg, Germany -- February 23, 2015 -- A new 16-bit 80251 microcontroller IP core shipping now from CAST, Inc. runs 69.7 times faster than the original 8051 chip, making it the ...
