Nuvoton Technology has launched a new NuMicro M031BT series: a low-power BLE 5.0 and 2.4GHz dual-mode microcontroller (MCU) series based on an Arm Cortex-M0 core operating up to 48 MHz, with up to 128KB flash and 16KB SRAM. In addition to the BLE 5.0 and 2.4GHz RF functions providing wireless connectivity, the NuMicro M031BT series offers built-in peripherals and analog functions applied to the applications that need advanced and precise control functions, such as industrial control that need wireless connectivity, sensor hubs in rigid working environments, says Nuvoton. The 5mm x 5mm QFN48 package greatly reduces the PCB size and RF layout difficulty. Nuvoton provides a reference design and sample code to speed up application development based on this M031BT low-power BLE/2.4G RF MCU.
The NuMicro M031BT series provides up to +8 dBm RF transmit power, a good receiving sensitivity of -94dBm, 1 Mb/s or 2 Mb/s transmission speed RF applications, and outstanding anti-noise performance in 2.4GHz interference environments to ensure communication range and reliability.
The NuMicro M031BT series operates from 1.8V to 3.6V. It features a built-in 32-bit hardware divider, up to 5-channel PDMA, a 16-channel 12-bit 2MSPS high sampling rate ADC that can run down to 1.8V low voltag, and 12-channel PWM running up to 96 MHz that can quickly respond and accurately control external devices. The M031BT also provides many peripherals such as one set of 24MHz SPI/I2S, three sets of 6 MHz UART supporting single-wire transmission, two sets of I2C and one set of highly flexible universal serial control interface (USCI) that can be configured as UART, I2C or SPI.
To protect the intellectual property rights, the NuMicro M031BT series is embedded with an additional security protection flash block (Security Protection ROM, SPROM) to provide an independent and secure encrypted execution area to protect critical program code. Flash lock bits are designed to provide firmware to prevent external access or write protection. A 96-bit unique chip identification (Unique Identification, UID) and a 128-bit unique customer identification (UCID) on each M031BT significantly improves product confidentiality and code security.
Nuvoton provides complete development tools, such as the NuMaker-M031BT evaluation board, software development kits, and sample codes, as well as free downloadable Keil MDK to speed up the end-product evaluation and development cycle. The NuMicro M031BT series is now available for 5mm x 5mm QFN48 package.
