APM32S103x8xB

Product Overview

Based on a 32-bit Arm® Cortex®-M3 core, the APM32S103x8xB series MCUs come with computing frequency up to 96MHz and a working temperature range of -40℃ to +105℃, helping products operate stably in industrial-grade temperature scenarios. With enhanced peripheral functions and 2 built-in CANs, it supports dual CAN operation at the same time.
