The circuit implements a programmable 0- to 20-mA precision current source...

Toshiba Electronics Europe has added the M4G Group to its TXZ Family of ARM Cortex-M-based microcontrollers for office automation equipment, audio-visual equipment, and industrial equipment...

Many PIC processors require 5-V power while being programmed, yet battery-powered systems may contain low-voltage devices that will be damaged at voltages above their maximum voltage ratings...

Batteries are the typical power sources for portable-system applications, and it is not unusual these days to find microcontroller-based portable systems. A variety of microcontrollers operates at low power-supply voltages, such as 1.8 V...

STMicroelectronics is boosting feature integration in low-cost, low-power 8-bit microcontrollers with the new STM8L050. As the latest in the ultra-energy-conscious STM8L series, it embeds rich analog peripherals, a DMA controller, and separated data EEPROM...

For most embedded designers, light-emitting diodes are simple components that are used as visual indicators. They typically involve a minimal circuit, and controlling the LED is typically only a matter of toggling the right logic level on a microcontroller's output pin...

Renesas Electronics expanded its Renesas Synergy S1 microcontroller series with the introduction of the S1JA MCU Group. The ultra-low power S1JA MCUs feature the 48 MHz Arm® Cortex-M23 core and integrate best-in-class programmable analog and security functions...

The STM8L001 ultra-low-power microcontroller from STMicroelectronics targets cost-conscious applications, by combining ST’s highly efficient 8-bit core with essential and effective peripherals, in the compact, low-pin-count SO-8 outline...

Few microcontrollers include a DAC. Although you can easily find an inexpensive DAC to control from your microcontroller, you can use unused peripherals instead of adding parts...

The enduring simplicity of PWM DACs will always earn them a place in the designer’s cookbook, but slow response time and the problem of PWM ripple tend to limit their appeal and utility. The usual way of attenuating PWM ripple, an RC low pass filter, can never succeed in completely eliminating it, and only makes output settling time agonizingly slow if you try...
