Introduction

This device is a 32-bit microcontroller based on the high-performance Arm Cortex-M3 core, operating at up to 72MHz with integrated high-speed embedded memory. It incorporates a comprehensive set of enhanced peripherals and I/O interfaces, suitable for a wide range of applications. The device operates from a 2.0V to 3.6V supply and is compatible with temperatures ranging from -40℃ to +85℃. All package options share an identical feature set. The device provides standard communication interfaces, including two I²C interfaces, three USART interfaces, two SPI interfaces, and one CAN interface. It also integrates a 12-bit ADC, two 12-bit DACs, two comparators, a low-power RTC, six general-purpose 16-bit timers, one PWM advanced-control timer, and two watchdog timers. The device is powered by a 2.0V to 3.6V supply and is available over a temperature range of -40℃ to +85℃. It is offered in a variety of package options ranging from 48-pin to 100-pin.
