Texas Instruments has introduced the MSPM0C1104, the world's smallest microcontroller. At just 1.38 mm² (approx. 0.00214 in²), the MCU equipped with an Arm Cortex-M0+ core enables space-saving designs in medical wearables and personal electronic devices.

Texas Instruments (TI) is expanding its MSPM0 portfolio with the world's smallest microcontroller, the MSPM0C1104. The new model in the wafer chip scale package (WCSP) measures just 1.38 mm² (approx. 0.00214 in²) - 38% smaller than comparable solutions - and is aimed at developers of compact embedded systems.

Despite its small size, the MCU offers solid performance with an Arm Cortex-M0+ core, 16 KB memory, a 12-bit ADC with three channels and six GPIO pins. Standard interfaces such as UART, SPI and I²C are supported. These features make it particularly interesting for applications with limited space, such as in-ear headphones or medical sensors.

The compact design of the MSPM0C1104 is made possible by the use of WCSP technology. This makes it possible to integrate more functions in smaller areas, allowing developers to realize more flexible designs without compromising performance. At the same time, the high level of integration helps to reduce the number of external components and therefore material costs.

The new MCU is part of TI's scalable MSPM0 series, which offers various memory and peripheral options. Thanks to pin compatibility within the product family, developers can easily switch between models to meet different requirements, from simple controllers to more powerful applications.

TI provides a comprehensive ecosystem to support development, including a software development kit, hardware prototyping boards and reference designs. With tools such as TI's Zero Code Studio, applications can also be implemented quickly and without in-depth programming knowledge.(sg)
