Texas Instruments has officially unveiled the MSPM0C1104, which it claims to be the world's smallest microcontroller. This remarkable device measures a mere 1.38 mm2, which is only slightly larger than a flake of black pepper.

The MSPM0C1104 is a wafer chip-scale package microcontroller (MCU) that is 38% smaller than existing alternatives, making it an ideal solution for applications where board space is at a premium, such as in medical wearables and personal electronics, all while maintaining essential functionality.

However, do not let its tiny size deceive you. The MSPM0C1104 is equipped with a complete 24 MHz Arm Cortex-M0+ processor, featuring 16 KB of flash memory, 1 KB of SRAM, a 12-bit ADC with three channels, and six GPIO pins that are compatible with standard communication interfaces, including Asynchronous Receiver Transmitter (UART), Serial Peripheral Interface (SPI), and Inter-Integrated Circuit (I2C).

The chip is also very power-efficient, drawing 87
