Overview

The STM32C011F4U6TR is an entry-level 32-bit microcontroller based on the Arm Cortex-M0+ core, designed to bridge the gap between 8-bit and 32-bit applications. Operating at 48MHz with 16KB of Flash and 6KB of RAM, it provides a cost-effective solution with a small 3x3mm UFQFPN20 footprint for space-constrained designs. The MCU includes essential peripherals like a 12-bit ADC, multiple timers, and standard serial interfaces while maintaining low power consumption.

Why Choose This Part

This MCU offers a significantly higher performance-to-cost ratio than traditional 8-bit microcontrollers while utilizing the modern Arm Cortex-M0+ architecture. It features a high-density 20-pin package with 18 available I/Os and 5V tolerance, simplifying interfacing with legacy hardware. The inclusion of a 12-bit SAR ADC with 15 channels provides high-resolution analog sensing in a very small PCB area.

Applications

Small Home Appliances
Ideal for controlling motor logic and user interfaces in blenders, coffee makers, or air purifiers where low cost and small physical size are priorities.
Sensor Hubs
Functions as a local controller to aggregate data from multiple sensors via I2C or SPI and transmit it to a main processor or communication module.
Simple Industrial Controllers
Suitable for basic PLC-like logic, valve control, or monitoring stations that require robust operation and 5V tolerant I/Os.
Battery-Powered Handhelds
Utilizes low-power modes such as Standby (12.5uA) and Shutdown (31nA) to extend battery life in simple portable devices.
