Introduction

MM32W0xxB is an ultra-low-power single-mode Bluetooth chip operating in the 2.4GHz ISM band with a 2MHz channel spacing, compliant with the Bluetooth specification. It features a high-performance 32-bit MCU based on the ARM Cortex-M0 core, with a maximum operating frequency of 48MHz, built-in high-speed memory, and rich enhanced I/O ports and peripherals connected to the external bus. The MM32W0xxB series incorporates one 12-bit ADC, four 16-bit general-purpose timers, one 32-bit general-purpose timer, one advanced PWM timer, as well as standard communication interfaces: two UART interfaces, one I2C interface, one SPI interface, one USB device interface, and one CAN interface. The product series operates at a supply voltage of 2.3V~3.6V, with multiple power-saving operating modes to meet the requirements of low-power applications. The product is available in LQFP48 and QFN32 packages; peripheral configurations may vary depending on the package type. These rich peripheral configurations make the MM32W0xxB MCU suitable for a wide range of applications.
