Overview

The STM32F103VET6TR is a high-density performance line microcontroller featuring an Arm Cortex-M3 core operating at a maximum frequency of 72MHz. This device is equipped with 512KB of Flash memory and 64KB of SRAM, making it suitable for applications requiring significant code space and data buffering. It includes a wide array of enhanced I/Os and peripherals, including a Flexible Static Memory Controller (FSMC) for external memory or LCD interfacing.

Why Choose This Part

This MCU offers a robust balance of processing power and peripheral density, including 16 channels of 12-bit ADC and dual 12-bit DACs. The 100-LQFP package provides 80 I/O pins, many of which are 5V tolerant, simplifying integration with legacy 5V digital logic.

Applications

Industrial Control Systems
Utilizes the integrated FSMC for managing external SRAM or NOR Flash and the 80 available I/Os for complex PLC or industrial controller designs.
Motor Control
Leverages the advanced-control PWM timers and high-speed 12-bit ADCs to implement precise field-oriented control for brushless motors.
Human Machine Interface (HMI)
The LCD parallel interface and large Flash capacity allow for driving medium-sized graphical displays and storing UI assets.
Communication Gateways
Integrates CAN 2.0B, USB 2.0 full speed, and multiple USARTs to bridge industrial protocols and PC-based monitoring systems.
