World’s Smallest Microcontroller: Texas Instruments Redefines Miniaturization
With the MSPM0C1104, TI reduces size by 38% compared to competitors, delivering high performance and flexibility for compact embedded devices
Isabella V12 March 2025
Texas Instruments introduced the world’s smallest MCU, the MSPM0C1104, 38% smaller than competing devices. This ultra-compact microcontroller, aimed at miniature embedded devices, offers high performance, low power consumption and a complete development ecosystem, simplifying integration into designs.
Key Points:
- Small size: 1.38 mm², 38% smaller than competing MCUs.
- Technical Specifications: 16 KB of memory, 12-bit ADC, six GPIOs, UART, SPI, I2C interfaces.
- Competitive cost: Starting at $0.16 per unit in quantities of 1,000.
- Development ecosystem: Hardware, software and simplified configuration tools support.
Texas Instruments introduced the smallest microcontroller ever, the MSPM0C1104, a unit that redefines the possibilities of integration into advanced embedded systems. With a surface area of just 1.38 mm², this part is designed to meet the miniaturization needs of sectors such as wearable technology, medical devices and consumer electronics, where every millimeter of space is essential. By reducing its footprint by 38% compared to the smallest MCUs currently available, the MSPM0C1104 allows designers to optimize board dimensions without sacrificing performance.
Despite its small size, the MCU integrates an advanced technical package: 16 KB of memory, a 12-bit analog-to-digital converter with three channels, six input/output pins and compatibility with major standard communication interfaces, such as UART, SPI and I²C. These features make it suitable for embedded systems that require precision, energy efficiency and reliable connectivity. The adoption of an eight-ball WCSP package not only reduces the footprint, but also optimizes thermal and electrical performance.
The MSPM0C1104 joins Texas Instruments’ MSPM0 portfolio, a family of microcontrollers based on the Arm® Cortex®-M0+ architecture, designed for scalability and flexibility. This enables developers to develop diverse products without significantly changing software or hardware, facilitating time to market and reducing design costs. With a price starting at $0.16 per unit in 1,000-piece quantities, it represents an affordable solution for companies of all sizes, from startups to large manufacturers.
In addition to hardware, Texas Instruments offers a complete development ecosystem, including software and hardware development kits, reference designs and intuitive configuration tools. Among these, Zero Code Studio stands out, a platform that allows developers to program the MCU without writing code, significantly simplifying the work of developers. This approach allows for faster design times and reduced complexity in the development of new devices.
The MSPM0C1104 will be officially unveiled at Embedded World 2025, March 11-13 in Nuremberg, Germany. Texas Instruments will use the event to demonstrate how its technology solutions can improve sensing and control capabilities in embedded systems, enabling new applications in industrial, consumer and medical fields.
The MCU represents a clear example of how advanced miniaturization can coexist with high performance, enabling the creation of increasingly smaller, more efficient and intelligent devices.
