MSP432P401x Ultra-Low-Power, Mixed-Signal MCUs

Texas Instruments' MSP432P401x MCUs feature low-power and high-performance, 32-bit ARM® Cortex®-M4F with 256 KB Flash and 64 KB RAM

Texas Instruments' SimpleLink™ MSP432P401x microcontrollers (MCUs) are optimized wireless host MCUs with an integrated 16-bit precision ADC, delivering ultra-low-power performance including 80 µA/MHz in active power and 660 nA in standby power with FPU and DSP extensions. As an optimized wireless host MCU, the MSP432P401x allows developers to add high-precision analog and memory extension to applications based on SimpleLink wireless connectivity solutions.

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

MSP432P401x devices are supported by a comprehensive ecosystem of tools, software, documentation, training, and support to get the development started quickly. The MSP-EXP432P401R LaunchPad™ development kit or MSP-TS432PZ100 target socket board (with additional MCU sample) along with the free SimpleLink MSP432 SDK is all the user needs to get started.
