Fast-settling synchronous-PWM-DAC filter has almost no
Fast-settling synchronous-PWM-DAC filter has almost no ripple

An inexpensive way to implement high-resolution digital-to-analog conversion is to combine microcontroller-PWM outputs with precision analog-voltage references, CMOS switches, and analog filtering. However, PWM-DAC design presents a big design problem: How do you adequately suppress the large ac-ripple component inevitably present in the switch’s outputs?...

Tough MCUs Optimized Rechargeable NiMH Applications
'Tough' MCUs Optimized for Rechargeable NiMH Applications

LAPIS Semiconductor has announced the development of the ML620130 family of 16 bit low power MCUs, optimized for compact industrial equipment requiring battery drive in noisy environments, featuring superior processing capability with low power consumption. In addition to clearing the ±30 kV noise measurement limit, operating voltage has been successfully reduced to 1.6 V...

Keyboard and display multiplexing - Charlieplexing

After my previous review of more traditional ways of reducing the I/O lines needed to drive LEDs/displays and keyboards/switches, here I'm looking at the nominally new method of Charlieplexing...

TI unveils first ultra-low power dual-band
TI unveils first ultra-low power dual-band wireless MCU in production

Expanding the functionality of Internet of Things networks, Texas Instruments announced availability for mass production of the industry's lowest-power dual-band wireless microcontroller supporting Sub-1 GHz and Bluetooth® low energy connectivity on a single chip. As part of TI's pin-to-pin and software compatible SimpleLink™ ultra-low power platform, the new SimpleLink dual-band CC1350 wireless MCU enables developers to move from a three-chip solution to a tiny single chip, while reducing design complexity, saving power, cost and board space...

Bye-bye ATmega328P Hello 328PB
Bye-bye ATmega328P, Hello 328PB!

We never have enough peripherals on a microcontroller. Whether it’s hardware-driven PWM channels, ADCs, or serial communication peripherals, we always end up wanting just one more of these but don’t really need so many of those. Atmel’s new version of the popular ATmega328 series, the ATmega328PB, seems to have heard our pleas...
