Texas Instruments Unveils World’s Smallest Microcontroller for Wearables and Electronics

The MSPM0C1104, measuring just 1.38 mm², offers high functionality, low power consumption, and affordability for space-constrained devices.

The MSPM0C1104 microcontroller, launched by Texas Instruments, is the smallest in the world at just 1.38 mm², approximately the size of a black pepper flake.
It features a 24 MHz Arm Cortex-M0+ processor, 16 KB of flash memory, 1 KB of SRAM, and a 12-bit analog-to-digital converter with three channels.
Designed for compact devices, the MCU is ideal for medical wearables, earbuds, and other space-constrained applications, operating efficiently across a wide temperature range (-40°C to 125°C).
The chip consumes only 87 μA/MHz when active and 5 μA in standby mode, making it highly power-efficient for battery-powered devices.
Priced at $0.16 per unit for bulk orders, the MSPM0C1104 is supported by a development ecosystem, including a $5.99 LaunchPad kit for prototyping and software tools for application development.
