The 8051 is alive and well. Cygnal Integrated Products has crammed a 25-MHz 8051 core, 8 kbytes of flash, and 256 bytes of data RAM into a tiny 11-pin, 3- by 3-mm (9 mm2) micro-lead package (MLP).

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 ...

Counter/timer hardware is a crucial component of most embedded systems. In some cases, a timer measures elapsed time (counting processor clock ticks). In others, we want to count or time external ...

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 life and embedded systems timing is everything. Give [Frank’s] web-based timer calculator a try. Set your system clock resolution (in hertz making sure you account for any system clock div… ...

An 8051-compatible microcontroller core with 26.85 times the performance per MHz of the original 8051 chip is now available from semiconductor intellectual property provider CAST, Inc.

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 ...

Although 8051-compatible microcontrollers with SPI ports are available, a lower-cost device with an SPI port bit-banged through GPIO pins often suffices.
