Nuvoton Technology launches the first Bluetooth low energy BLE 5.0 and 2.4G dual-mode microcontroller-M031BT series

May 18, 2020
Nuvoton Technology today announced the launch of NuMicro® M031BT BLE 5.0 Bluetooth low energy microcontroller series, with Arm® Cortex®-M0 as the core, operating frequency up to 48 MHz, built-in 128 KB Flash and 16 KB SRAM, providing BLE 5.0 And 2.4 GHz dual mode function. Compared with the traditional BLE SoC with simple integrated peripherals, NuMicro® M031BT series has built-in rich peripherals and excellent analog control functions to realize the solution of a microcontroller replacing BLE SoC and control chip. With 5mm x 5mm, it also reduces the difficulty of RF layout, and Nuvoton's reference design scheme and sample code make the development of low-power Bluetooth applications very easy.

NuMicro® M031BT series provides RF transmission power up to +9 dBm, good reception sensitivity of -92 dBm, 1 Mb / s or 2 Mb / s transmission speed for RF applications, and can provide outstanding Anti-noise performance, improve communication distance and reliability, and meet the needs of application scenarios such as smart home, consumer electronics and industrial Internet of Things.

NuMicro® M031BT series operates from 1.8V to 3.6 V operating voltage, built-in 32-bit hardware multiplier / divider, up to 5-channel PDMA, 16-channel 12-bit 2 MSPS high sampling rate ADC can run at 1.8V low voltage, provides Accurate and fast performance, 12-channel 96 MHz PWM can quickly respond and accurately control external devices. In addition, M031BT also provides a wealth of peripherals, such as 1 set of 24 MHz SPI / I2S, 3 sets of 6 MHz UART and can support single-wire transmission, 2 sets of I2C, 1 set of highly flexible universal serial control interface (USCI) can be set UART, I2C or SPI.

In order to protect the intellectual property rights of developers, NuMicro® M031BT series embeds an additional security protection Flash block (SPROM, Security Protection ROM), providing an independent and secure encryption execution area to protect key program code. Memory lock function (Flash lock bits) design provides firmware to prevent external access or write protection. Each M031BT has a 96-bit unique identification number (UID) and a 128-bit unique customer identification number (UCID), which greatly improves the product's confidentiality and code security.

Nuvoton provides complete development tools, in addition to NuMaker-M031BT development board, software development kit and sample code, and provides free download of Keil MDK to accelerate the end product evaluation and development cycle.

The NuMicro® M031BT series not only provides excellent radio frequency networking, but also provides low-power Bluetooth BLE 5.0 and 2.4G dual-mode communication methods, which greatly reduces transmission power consumption, extends battery life, and allows microcontrollers that were previously unconnected The device is quickly upgraded to become a member of the Internet of Things. In response to future development, Nuvoton Technology will continue to launch a new series of low-power Bluetooth microcontrollers for consumer, industrial control, home and vehicle applications.
