The high-performance ARM? Cortex?-M0 32-bit RISC engine, working at up to 48 MHz frequency, high-speed embedded storage (up to 32 Kbytes of Flash memory and 6 Kbytes of SRAM), and a wide variety of improved peripherals and I/Os are all included in the STM32F042x4/x6 microcontrollers. All of the devices provide the industry-standard interfaces for communication, including one I2C, two SPIs/one I2S, one HDMI CEC, two USARTs, one CAN, one 12-bit ADC, four 16-bit timers, one 32-bit timer, and one advanced-control PWM timer.

When powered by a 2.0 to 3.6 V power source, the STM32F042x4/x6 microcontrollers function in the -40 to +85 °C and -40 to 105 °C temperature ranges, respectively. The development of low-power applications is made possible by a wide range of power-saving modes.
