The STM32F042x4/x6 microcontrollers incorporate the high-performance
ARM® Cortex®-M0 32-bit RISC core operating at up to 48 MHz frequency, high-speed
embedded memories (up to 32 Kbytes of Flash memory and 6 Kbytes of SRAM), and an
extensive range of enhanced peripherals and I/Os. All devices offer standard
communication interfaces (one I2C, two SPIs/one I2S, one HDMI CEC and two USARTs),
one USB Full-speed device (crystal-less), one CAN, one 12-bit ADC, four 16-bit timers, one
۳۲-bit timer and an advanced-control PWM timer.
The STM32F042x4/x6 microcontrollers operate in the -40 to +85 °C and -40 to +105 °C
temperature ranges, from a 2.0 to 3.6 V power supply. A comprehensive set of
power-saving modes allows the design of low-power applications.
