DescriptionThe STM32F042x4/x6 microcontrollers incorporate the high-performanceARM174; Cortex174;-M0 32-bit RISC core operating at up to 48 MHz frequency, high-speedembedded memories (up to 32 Kbytes of Flash memory and 6 Kbytes of SRAM), and anextensive range of enhanced peripherals and I/Os. All devices offer standardcommunication 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, one32-bit timer and an advanced-control PWM timer.The STM32F042x4/x6 microcontrollers operate in the -40 to +85 °C and -40 to +105 °Ctemperature ranges, from a 2.0 to 3.6 V power supply. A comprehensive set ofpower-saving modes allows the design of low-power applications.The STM32F042x4/x6 microcontrollers include devices in seven different packages rangingfrom 20 pins to 48 pins with a die form also available upon request. Depending on thedevice chosen, different sets of peripherals are included.These features make the STM32F042x4/x6 microcontrollers suitable for a wide range ofapplications such as application control and user interfaces, hand-held equipment, A/Vreceivers and digital TV, PC peripherals, gaming and GPS platforms, industrial applications,PLCs, inverters, printers, scanners, alarm systems, video intercoms and HVACs
