Texas Instruments MSP432P411xT/MSP432P401xT MCUs

Texas Instruments SimpleLink MSP432P411xT / MSP432P401xT Microcontrollers (MCUs) are optimized wireless host MCUs with an integrated 16-bit precision ADC. These MCUs deliver ultra-low-power performance, including 100µA/MHz in active power and 14.4µA in standby power with FPU and DSP extensions. As an optimized wireless host MCU, the MSP432P411xT and MSP432P401xT let developers add high-precision analog and memory extensions to applications based on SimpleLink wireless connectivity solutions. The Texas Instruments MSP432P411xT and MSP432P401xT devices are part of the SimpleLink MCU platform, which consists of Wi-Fi, BLUETOOTH® low energy, Sub-1 GHz, and host MCUs.
