SimpleLink Ultra-Low-Power 32-Bit Arm Cortex-M4F MCU with Precision ADC, 1MB Flash and 256KB RAM



The SimpleLink MSP432P411x and MSP432P401x microcontrollers (MCUs) are optimized wireless host MCUs with an integrated 16-bit precision ADC, delivering ultra-low-power performance including 100 µA/MHz in active power and 820 nA in standby power with FPU and DSP extensions. As an optimized wireless host MCU, the MSP432P411x and MSP432P401x let developers add high-precision analog and memory extension to applications based on SimpleLink wireless connectivity solutions.

The MSP432P411x and MSP432P401x devices are part of the SimpleLink MCU platform, which consists of Wi-Fi, Bluetooth low energy, Sub-1 GHz, and host MCUs. All share a common, easy-to-use development environment with one core software development kit (SDK) and a rich tool set. A one-time integration of the SimpleLink platform lets you add any combination of devices from the portfolio into your design. The ultimate goal of the SimpleLink platform is to achieve 100 percent code reuse when your design requirements change. For more information, visit

MSP432P411x and MSP432P401x MCUs are supported by a comprehensive ecosystem of tools, software, documentation, training, and support to get your development started quickly. The LaunchPad™ development kit or MSP-TS432PZ100 target socket board (with additional MCU sample) along with the free SimpleLink MSP432 SDK are all you need to get started.
