APM32 Microcontrollers
APM32E103xCxE
Product Overview
Based on a 32-bit Arm® Cortex®-M3 core, the APM32E103xE industrial-grade enhanced MCU is upgraded on the Geehy APM32F103xE series. Its operating frequency can reach 120MHz, the power supply is from 2.0V to 3.6V, and the operating temperature covers -40℃ to +105℃, helping products to operate stably in industrial-grade temperature scenarios. The new APM32E103xE is equipped with rich on-chip resources and can bring better choices for users' applications with enhanced functions and cost-effective performance.
