Texas Instruments has introduced the MSPM0C1104, which it describes as the world's smallest microcontroller, expanding its MSPM0 MCU portfolio. Measuring only 1.38mm², this wafer chip-scale package MCU is 38% smaller than existing alternatives. It is designed for applications where board space is limited, such as medical wearables and personal electronics, while maintaining functionality. The MSPM0C1104 includes a 24MHz Arm Cortex-M0+…
Most embeddable medical devices need wireless to share out data and get OTA updates. Unless you’re doing wired things, in which case MCU size may not matter.
On second thought… a medical device that goes in one end, collects data, and comes out the other end. OK, that may not need wireless… and it better be small.

As cool as the TI is, I’d look at the new SiLabs BG29 for processing + BLE: https://news.silabs.com/2025-03-12-Silicon-Labs-Unveils-BG29-The-Future-of-Bluetooth-R-LE-in-Miniature-Devices
