Description
The STM32F030x microcontroller incorporates the high-performance ARM Cortex™-M0 32-bit RISC core operating at a 48 MHz frequency, high-speed embedded memories (up to 64 Kbytes of Flash memory and up to 8 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 two USARTs), one 12-bit ADC, up to 6 general-purpose 16-bit timers and an advanced-control PWM timer.
The STM32F030x microcontroller operates 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 STM32F030x microcontroller includes 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 STM32F030x peripherals proposed.
These features make the STM32F030x microcontroller 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 platforms, e-bikes, consumer appliances, printers, scanners, alarm systems, video intercoms, and HVACs.
