Nuvoton Technology launches new NuMicro M031BT/M032BT series: Low-Power BLE 5.0 and 2.4G Dual-Mode Microcontroller

    Nuvoton Technology launches new NuMicro M031BT/M032BT series: a low-power BLE 5.0 and 2.4 GHz dual-mode microcontroller series based on Arm Cortex-M0 core operating up to 72 MHz, with up to 512 KB Flash and 96 KB SRAM. In addition to the BLE 5.0 and 2.4GHz RF wireless connectivity, the NuMicro M031BT/M032BT series feature built-in rich peripherals and analog functions for applications that need advanced and precise control functions in industrial control applications that it also requires wireless connectivity for sensor hubs in rigid working environments. The 5mm x 5mm QFN48 and 8mm x 8mm QFN68 package reduce the PCB size and RF layout difficulty. Furthermore, Nuvoton provides reference designs and rich sample codes to speed up the application development based on this M031BT/M032BT low-power BLE/2.4G RF microcontroller.

    The NuMicro M031BT/M032BT series provide up to +8 dBm RF transmit power, a good receiving sensitivity of -94 dBm, 1 Mb/s, or 2 Mb/s transmission speed RF applications, and outstanding anti-noise performance in 2.4GHz interference environments to ensure communication distance and reliability. With these, the M031BT/M032BT series are expected to meet the needs of application scenarios such as industrial Internet of Things (IIoT), smart home, consumer electronics, etc.

    The NuMicro M031BT/M032BT series operate at a voltage ranging from 1.8V to 3.6V. They feature a built-in 32-bit hardware divider, up to 9-channel PDMA, a 16-channel 12-bit 2 MSPS high sampling rate ADC that can run down to 1.8V low voltage, and 24-channel PWM running up to 144 MHz that can quickly respond and accurately control external devices. Besides, M031BT/M032BT also provide many peripherals such as one set USB, eight sets of 6 MHz UART supporting single-wire transmission, two sets of I2C, and up to two sets of highly flexible universal serial control interface (USCI) that can be configured as UART, I2C or SPI.

    To protect intellectual property rights, the NuMicro M031BT/M032BT series are embedded with an additional security protection Flash block (Security Protection ROM, SPROM) to provide an independent and secure encrypted execution area protect critical program code. Flash lock bits are designed to provide firmware to prevent external access or write protection. In addition, there is a 96-bit unique chip identification (Unique Identification, UID) and a 128-bit unique customer identification (UCID) on each M031BT/M032BT, which significantly improves product confidentiality and code security.

    Nuvoton provides complete development tools, such as the NuMaker-M031BT and NuMaker-M032BT evaluation boards, software development kits, and sample codes. In addition, free downloadable Keil MDK is available to speed up the end-product evaluation and development cycle.

    The M031BT/M032BT series provide rich digital and analog peripherals, low-power Bluetooth BLE 5.0 and 2.4G dual-mode communication, and excellent radio frequency networking functions. These features significantly reduce transmission power consumption, prolong battery life, and allow traditional microcontrollers with rich control functions for IIoT that need wireless connectivity. Nuvoton Technology would continue releasing new low-power Bluetooth microcontrollers for consumer devices, industrial control, smart home, and automotive applications.
