STMicroelectronics STM32F042K4U6

STM32F042K4U6                        Description   The STM32F042x4/x6 microcontroller integrates a high-performance ARM Cortex - M0 32-bit RISC core that runs at up to 48 MHz, high-speed embedded memory (up to 32K bytes of flash memory and 6K bytes of SRAM), and a wide range of enhanced peripherals and IMago. All devices provide standard communication interfaces (one I2C, two SPI/ and one I2S, one HDMI CEC and two USART), one USB full-speed device (without crystals), one CAN, one 12-bit ADC, four 16-bit timers, one 32-bit timer and one advanced control PWM timer. The STM32F042x4/x6 microcontroller operates in the temperature range of-40 to 85 °C and from-40 to 105 °C with a supply voltage of 2.0 to 3.6V. A comprehensive set of power-saving modes allows the design of low-power applications.
