The STM32F042K4U6 is a 32-bit ARM Cortex-M0 microcontroller from STMicroelectronics, operating at 48MHz. It features 16KB flash and 6KB RAM in a 32-UFQFN package. With a supply range from 1.65V to 3.6V and integrated DMA, I2S, PWM, and WDT, it is optimized for low-power and space-constrained applications.
- Ultra-low voltage operation (1.65V) – extends battery life in portable devices.
- 48MHz Cortex-M0 – sufficient for real-time control tasks.
- 6KB RAM – larger buffer for data-intensive applications.
- Small UFQFN package – ideal for miniaturized PCBs.
Battery-Powered Sensors
Operate down to 1.65V, enabling direct CR2032 coin-cell use for wireless sensor nodes.
USB Peripherals
Use the 48MHz core and DMA to handle USB enumeration and data transfer in HID devices.
Motor Drivers
