Introduction

A 32-bit microcontroller based on the high-performance Arm Cortex®-M0 core, operating at up to 48MHz, with built-in high-speed memory and rich I/O ports and peripherals connected to the external bus. Includes 1 × 12-bit ADC, 1 × 16-bit general-purpose timer, 1 × 16-bit basic timer, and 1 × 16-bit advanced timer. Also features standard communication interfaces: 1 × I2C, 1 × SPI, and 2 × UART. Operating voltage: 2.0V~5.5V. Operating temperature range (ambient): industrial grade -40°C~+85°C and extended industrial grade -40°C~+105°C (suffix V). Built-in multiple power-saving modes to meet low-power application requirements. This rich peripheral configuration makes the microcontroller suitable for a wide range of applications. Available in 3 package options: QFN20, TSSOP20, and SOP8.
