The STM32F042C4T6 is a 32-bit microcontroller from STMicroelectronics, built on the energy-efficient ARM Cortex-M0 core. It delivers 48MHz performance with 16KB flash and 6KB SRAM, packaged in a compact 48-LQFP. Its rich peripheral set includes DMA, I2S, PWM, and multiple communication interfaces, all operating from a flexible 1.65V to 3.6V supply. This MCU is designed for cost-sensitive embedded applications requiring a balance of processing power and low power consumption.
- Ultra-low voltage operation (1.65V) – Enables direct battery operation without a regulator, reducing BOM cost and power loss.
- 48MHz Cortex-M0 performance – Provides sufficient compute headroom for real-time control loops while maintaining simplicity of the M0 architecture.
- Integrated I2S and DMA – Allows glueless audio streaming and peripheral-to-memory transfers without CPU loading, ideal for multimedia applications.
- Wide temperature range (-40°C to 85°C) – Ensures reliable operation in industrial and outdoor environments.
