Overview

The STM32F031K6T6 is an entry-level 32-bit microcontroller based on the ARM Cortex-M0 core, designed for cost-sensitive embedded control applications. Operating at up to 48MHz, it provides a balanced mix of 32KB Flash and 4KB RAM in a compact 32-pin LQFP package. It is particularly effective for bridge functions and simple peripheral control where a small footprint and low power consumption are required.

Why Choose This Part

This MCU offers a high performance-to-cost ratio by providing 32-bit processing power and a 5-channel DMA at a price point comparable to 8-bit alternatives. It features 5V-tolerant I/Os, which simplifies interfacing with legacy logic and industrial sensors in mixed-voltage environments.

Applications

Sensor Interface Hub
Aggregates data from multiple analog and digital sensors using the 12-bit ADC and I2C/SPI interfaces.
Handheld Control Devices
Utilizes low-power modes (Sleep, Stop, Standby) to extend battery life in portable user-interface equipment.
Simple Motor Control
Leverages dedicated PWM timers for basic DC or brushless motor speed regulation in consumer appliances.
System Supervisor
Acts as a housekeeping controller for larger systems, managing power sequencing via POR/PDR and PVD features.
