World's smallest microcontroller looks like I could easily accidentally inhale it but packs a genuine 32-bit Arm CPU
A sneeze-inducing 1.38 mm² and small enough to make a Raspberry Pi look like a bus.
Despite the diminutive proportions, which Texas Instruments claims to be 38% smaller than any other MCU, this teensy spec of a chip packs a fully functional Arm 32-bit Cortex-M0+ CPU core running at a towering 24 MHz. Unfortunately, Texas Instruments doesn't quote a process node or transistor count, so it's a little hard to get an overall feel for the complexity level and performance of the chip. "Consumers are continuously demanding that everyday electronic items, such as electric toothbrushes and stylus pens, offer more features in a smaller footprint at a lower cost," Texas Instruments says, and the MSPM0C1104 chip will help enable that.
