🇺🇦 haxadecimal<p>Dear Lazyweb,<br>What 32-bit <a href="https://mastodon.social/tags/microcontroller" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>microcontroller</span></a> (i.e., Cortex-M or RV32, not a Linux application processor) has the highest Coremark/mW, or lowest uA/MHz? A quick search suggests Ambiq Apollo 4 or ST STM32U3, but are there others I should look at?<br>I want the maximum CPU performance I can get powered by a CR2032 coin cell at under 1 mA current. (CR2032 useful lifetime decreases dramatically above that.)</p>
