New Part Day: Smallest ARM MCU Uproots Competition, Needs Research

The teeny tiny MCU mentioned in the article, merely a blimp on a giant devboard

We’ve been contacted by [Cedric], telling us about the smallest MCU he’s ever seen – Huada HC32L110. For those of us into miniature products, this Cortex-M0+ package packs a punch …read more Continue reading New Part Day: Smallest ARM MCU Uproots Competition, Needs Research

No Caffeine, No Problem: A Hand-Soldered Chip-Scale Package

It’s said that the electronic devices we use on a daily basis, particularly cell phones, could be so much smaller than they are if only the humans they’re designed for weren’t so darn big and clumsy. That’s only part of the story — battery technology has a lot to do with overall device size — but it’s true that chips can be made a whole lot smaller than they are currently, and are starting to bump into the limit of being able to handle them without mechanical assistance.

Or perhaps not, if [mitxela]’s hand-soldering of a tiny ball-grid array chip …read more
