So you could fit about 200 of these things in the space the Broadcom BCM2712 takes up.<\/p>\n<p>Despite the diminutive proportions, which Texas Instruments claims to be 38% smaller than any other MCU, this teensy spec of a chip packs a fully functional Arm 32-bit Cortex-M0+ CPU core running at a towering 24 MHz. It also has 16 KB of flash memory and 1 KB of SRAM.<\/p>\n<p>In broad terms, that seems to put it about on par with an Intel 386 chip from 1985, which offered clock speeds from 12.5 MHz up to 40 MHz and 16 KB of L2 cache. Unfortunately, Texas Instruments doesn&#8217;t quote a process node or transistor count, so it&#8217;s a little hard to get an overall feel for the complexity level and performance of the chip.<\/p>\n<figure class=\"van-image-figure inline-layout\" data-bordeaux-image-check >\n<div class='image-full-width-wrapper'>\n<div class='image-widthsetter' style=\"max-width:1159px;\">\n<p class=\"vanilla-image-block\" style=\"padding-top:66.52%;\"><img loading=\"lazy\" decoding=\"async\" id=\"9UdK7NBSvdFxr6w946iPM5\" name=\"Texas Instruments MSPM0C1104\" alt=\"Texas Instruments MSPM0C1104 on an earbud\" src=\"https:\/\/arcader.org\/wp-content\/uploads\/2025\/03\/worlds-smallest-microcontroller-looks-like-i-could-easily-accidentally-inhale-it-but-packs-a-genuine-32-bit-arm-cpu.png\" mos=\"\" align=\"middle\" fullscreen=\"\" width=\"1159\" height=\"771\" attribution=\"\" endorsement=\"\" class=\"\"><\/p>\n<\/div>\n<\/div><figcaption itemprop=\"caption description\" class=\" inline-layout\"><span class=\"caption-text\">The Texas Instruments MSPM0C1104 is so small, it makes an earbud look like a bus <\/span><span class=\"credit\" itemprop=\"copyrightHolder\">(Image credit: Texas Instruments )<\/span><\/figcaption><\/figure>\n<p>Still, it also sports a 12-bit ADC or analogue-to-digital converter with three channels and it&#8217;s listed on Texas Instruments&#8217; website as an automotive mixed-signal microcontroller but is designed for small systems like earbuds and medical devices.<\/p>\n<p>&#8220;Consumers are continuously demanding that everyday electronic items, such as electric toothbrushes and stylus pens, offer more features in a smaller footprint at a lower cost,&#8221; Texas Instruments says, and the MSPM0C1104 chip will help enable that.<\/p>\n<p>Oh, and the price?
