This Arm Cortex-MO+ powered MCU was showcased at Embedded World.

TI is targeting medical wearables and personal electronic applications for the new MSPM0C1104, which it claims is 38% smaller than the most compact rival MCUs and will cost buyers just 20 cents a piece in bulk. As per the definition of an MCU, TI’s MSPM0C1104 contains all the essential ingredients of a self-contained computer, albeit on a scale smaller than we are used to talking about on Tom’s Hardware. However, powering over 100 third-party boards with a diverse range of prices, features, and capabilities, the RP2040 and RP2350 make great options for smaller-volume device makers who don’t absolutely need the tiniest MCU/board available.
