The STM32F030x4/x6/x8/xC microcontrollers have a high-performance Arm?Cortex?-M0 32-bit RISC core running at 48 MHz, high-speed embedded storage (up to 256Kbytes of Flash memory and 32Kbytes of SRAM), and a wide range of upgraded peripherals and I/Os. Standard communication interfaces (up to two I2Cs, two SPIs, and up to six USARTs) are available on all devices, as well as one 12-bit ADC, seven general-purpose 16-bit timers, and one advanced-control PWM timer. From a 2.4 to 3.6V power supply, the STM32F030x4/x6/x8/xC microcontrollers work in the temperature range of -40 to 85 ?C. Low-power applications can be designed thanks to a wide collection of power-saving options. The STM32F030x4/x6/x8/xC microcontrollers are available in four different package sizes ranging from 20 to 64 pins. Different sets of peripherals are included depending on the device. The following description provides an overview of the entire scope of STM32F030x4/x6/x8/xC peripherals proposed. These characteristics make the STM32F030x4/x6/x8/xC microcontrollers suitable for a variety of applications, including application control and user interfaces, handheld equipment, A/V receivers and digital TV, PC peripherals, gaming and GPS portals, industrial uses, PLCs, inverters, printers, scanners, alarm systems, video intercoms, and HVACs.
