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 ...

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.

The TI MSPM0C1104 accommodates the 32-bit ARM Cortex-M0+ core, 1 KByte RAM and 16 KByte flash on 1.6 mm × 0.861 mm. There is very little space in some devices, for example in smartwatches, in-ear ...

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 ...
