The STM32F030x4/6/8/C microcontrollers incorporate the high-performance ARM?Cortex?-M0 32-bit RISC core operating at a 48 MHz frequency， high-speed embedded memories (up to 256 Kbytes of Flash memory and_up to 32 Kbytes of SRAM)， and_an extensive range of enhanced peripherals and_I/Os. All devices offer standard communication interfaces (up to two I2Cs， up to two SPIs and_up to six USARTs)， one 12-bit ADC， seven general-purpose 16-bit timers and_an advanced-control PWM timer.

The STM32F030x4/6/8/C microcontrollers operate in the -40 to +85 °C temperature range from a 2.4 to 3.6 V power supply. A comprehensive set of power-saving modes allows the design of low-power applications.

The STM32F030x4/6/8/C microcontrollers include devices in four different packages ranging from 20 pins to 64 pins. Depending on the device chosen， different sets of peripherals are included. The description below provides an overview of the complete range of STM32F030x4/6/8/C peripherals proposed.

These features make the STM32F030x4/6/8/C microcontrollers suitable for a wide range of applications such as application control and_user interfaces， handheld equipment， A/V receivers and_digital TV， PC peripherals， gaming and_GPS platforms， industrial applications， PLCs， inverters， printers， scanners， alarm systems， video intercoms， and_HVACs.
