On March 11, 2025, TI announced the launch of the world’s smallest microcontroller (MCU).
The new MCU, MSPM0C1104, is 38% smaller than the smallest MCU currently available in the industry, claiming the title of the world’s smallest MCU with a size of 1.38 square millimeters. This allows designers to minimize PCB space without compromising performance.
The MSPM0C1104 MCU adopts a wafer chip-scale package (WCSP), optimizing size and performance for compact applications such as medical wearables and personal electronics. This miniature package is designed to make consumer electronic devices, such as electric toothbrushes and styluses, smaller and more cost-effective.

1. How does such a tiny chip perform?
The MSPM0C1104 MCU features a 24MHz Arm® Cortex®-M0+ core, 1KB SRAM, 16KB memory, an operating voltage range of 1.62V to 3.6V, a 12-bit analog-to-digital converter with three channels, and six general-purpose I/O pins. The MCU also integrates a high-speed on-chip oscillator with an accuracy range of -2% to +1.2%, eliminating the need for an external crystal oscillator. It is compatible with standard communication interfaces such as UART, SPI, and I²C, features 5V-tolerant I/O, and includes DMA. Additionally, it supports an extended operating temperature range from -40°C to 125°C.
By integrating precise and high-speed analog components into the world’s smallest MCU, engineers gain the flexibility to maintain computational performance in embedded systems without increasing PCB size.
The new MSPM0C1104 joins TI’s MSPM0 MCU product lineup, providing scalability for the entire platform through a variety of analog and digital peripherals, memory, and computing features. This enables it to meet specific application requirements in personal electronics, industrial, and automotive applications while offering low-power modes to extend battery life. It also provides pin-to-pin compatible packaging options, including other small packages. The price starts at $0.16 for orders of 1,000 units.
