Texas Instruments has introduced the smallest microcontroller (MCU), the MSPM0C1104, and it’s about the size of 1.38mm². Despite its tiny size, this little chip is packed with power, making it perfect for super-compact devices like medical wearables, earbuds, and stylus pens. This tiny MCU is 38% smaller than other compact options, giving engineers more room to add features without increasing size or cost. It’s a smart solution for making smaller, more efficient devices.
Even though it’s small, it doesn’t compromise on performance. The MSPM0C1104 comes with 16KB of memory, a 12-bit analog-to-digital converter, and six general-purpose input/output pins. It also supports common communication interfaces like UART, SPI, and I2C, making it easy to integrate into various designs. Due to TI’s advanced chip technology, this MCU not only saves space but also improves power efficiency, helping devices run longer on a single charge. Its Wafer Chip-Scale Package (WCSP) design plays a big role in keeping it ultra-compact while still delivering strong performance.
TI’s MSPM0 MCU lineup makes it easy for engineers to scale their designs, whether for personal gadgets, industrial tools, or even automotive applications. Additionally, TI provides handy development tools, like Zero Code Studio, to speed up the design process and make prototyping easy. For those looking to test and experiment quickly, TI offers the MSPM0C1104 LaunchPad development kit for just $5.99, making it accessible for engineers at all levels.
This small but capable MCU helps designers save space while keeping performance intact, making it ideal for compact devices like wearables and personal electronics. Additionally, with a price of just $0.20 per unit (in 1,000-unit quantities), it’s a cost-effective choice for mass production. As the need for smaller, more efficient technology grows, solutions like this will play a key role in future designs.
