Texas Instruments (TI) unveiled the MSPM0C1104 at Embedded World 2025 in Nuremberg, Germany. This device is now the world’s smallest microcontroller (MCU). Measuring just 1.38mm²—smaller than a black pepper flake—the new MCU is 38% more compact than the smallest existing model. This unprecedented size makes it ideal for highly space-constrained applications like medical wearables and personal electronics.
