ST STM32F031K4U6

STM32F031K4U6                  Description

  The STM32F031x4/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 4K bytes of SRAM), and a wide range of enhanced peripherals and IMago. All devices provide standard communication interfaces (an I2C, an SPI/I2S and a USART), a 12-bit ADC, five 16-bit timers, a 32-bit timer and an advanced control PWM timer. The STM32F031x4/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. The STM32F031x4/x6 microcontroller includes six different packaged devices with pins ranging from 20 to 48 pins and available in core form upon request. Different groups of peripherals are included depending on the selected device. These features make STM32F031x4/ x6 microcontrollers suitable for a wide range of applications such as application control and user interfaces, handheld devices, Amax V receivers and digital TVs, PC peripherals, games and GPS platforms, industrial applications, PLC, inverters, printers, scanners, alarm systems, video walkie-talkies and HVAC.
