If you thought the Raspberry Pi's chip was dinky, well, get a load of the nattily named Texas Instruments MSPM0C1104, said to the world's smallest microcontroller or MCU and measuring a mere 1.38 mm².

It’s smaller than a pepper grain but don’t let its tiny size fool you. Texas Instruments has unveiled the world’s smallest microcontroller, the MSPM0C1104, measuring a mere 1.38 square millimeters.

It’s generally pretty easy to spot a microcontroller on a PCB. There are clues aplenty: the more-or-less central location, the nearby crystal oscillator, the maze of supporting passives, and perhaps ...

According to Texas Instruments, it has developed the smallest microcontroller available, expanding the company's Arm Cortex-M0+ MSPM0 MCU portfolio. The 1.38-mm 2 wafer chip-scale packaged (WCSP) ...

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 ...
