MindMotion Introduces Low Power Bluetooth MM32WB0510 MCU with BLE 5.1 Support

MindMotion launched the MM32WB0510 microcontrollers with an integrated Bluetooth Low Energy (BLE) RF module that complies with the BLE 5.1 specification.

The MM32WB0510 series MCU features an integrated BLE 5.1 RF module that operates in the 2.4GHz ISM band, and its RF front end uses GFSK/FSK modulation to support programmable frequency channels and output power. It supports communication rates of 1Mbps and 2Mbps. The software package includes support for HID and NUS (Nordic UART) profiles and provides a small form factor stack that consumes only 12KB of Flash and 2KB of RAM. The module has been tested for compatibility with common PC or mobile phone devices.

The MM32WB0510 series is equipped with an Arm Cortex-M0 core that operates at up to 72MHz. It comes with built-in 128KB Flash storage, and 16KB SRAM and integrates USB and FlexCAN interfaces for wireless or multi-interface applications such as smart homes, keyboards, mice, fire-fighting field components, power electronics, automotive OBUs, automotive sensors, etc. The MM32WB0510 is available in various packages, including LQFP64, LQFP48, QFN48, and QFN32 packages.

Key Features of the MM32WB0510

Two high-speed analog comparators.

• All series support -40℃ to 85℃ industrial tier operating temperature range.

Hardware and Software

MindMotion provides the Mini-WB0513-OB development board for the MM32WB0510 series, which comes equipped with a 2.4GHz PCB antenna and an MM32-LINK on-board debugger. The board features several on-board interfaces including an IPEX-1 antenna holder, two USB Type-C, two 5P 1.27mm external emulator connectors, and the MM32WB0513D6N full-pin expansion connector. The Mini-WB0513-OB is powered through USB Type-C.

The software package is based on Libsamples and provides common routines such as Bluetooth stack, NUS (Nordic UART) pass-through, and HID (Human-Interface Device) service.
