Overview

The STM32F042K6T6 is a 32-bit ARM Cortex-M0 microcontroller designed for entry-level applications requiring USB 2.0 crystal-less functionality and CAN bus connectivity. Operating at 48MHz, it offers a compact 32-pin LQFP footprint with integrated clock recovery for USB, reducing external component count and bill-of-materials costs.

Why Choose This Part

This MCU features a unique internal clock trimming system that eliminates the need for an external crystal in USB applications. It provides a wide operating voltage from 2V to 3.6V and includes 5V-tolerant I/O, simplifying the interface to legacy digital logic.

Applications

USB Peripherals
Utilizes the internal 48MHz oscillator with automatic trimming for crystal-less USB 2.0 full-speed device implementations.
Industrial CAN Nodes
Integrated CAN bus controller makes it suitable for small-footprint industrial sensor nodes and gateway devices.
Human Interface Devices (HID)
Built-in capacitive sensing channels support touch keys and proximity sensors for modern user interfaces.
Consumer Electronics Control
Integrated HDMI-CEC hardware allows for easy integration into home theater and media center control systems.
