The STM32F030 features an ARM Cortex core and runs at speeds up to 48 MHz. While achieving the STM32’s lowest ever price point, the STM32F030 comes with a full set of high-performance peripherals, such as fast 12-bit ADC, advanced and flexible timers, RTC calendar and communication peripherals such as I²C, USART and SPI.
This combination easily outperforms existing 8-bit architectures and allows all application designers to benefit from the simplicity and efficiency of a state-of-the-art 32-bit core. The STM32F030 Value line covers many memory and pin count combinations with only a few competitive devices and thus further enhances the overall cost efficiency of your projects.
Application designers starting with the STM32F030 benefit from being able to upgrade to any of the devices in the powerful STM32 portfolio at any time with an high degree of reusability of tools and application software.

3. STM32F070 USB value line objectives
Add USB peripheral in our STM32F0 Value Line
Consumer market in CGA/TW/South Asia/Korea mainly for basic USB bridge function (USB/UART, USB/I2C, USB/SPI) in various application domains. So USB value devices make sense.
Improved our price competitiveness in a market dominated by Nuvoton NUC bit Cortex M0 USB family $0.68 POS and below) or 8-bit traditionnal USB MCU from Cypress, Microchip/SCMC, and 8051-based MCUs (Sillabs etc…)

STM32 F0 Entry-level Cortex®-M0 MCUs
Devices in ST’s ARM® Cortex-M0-based STM32 F0 series deliver 32-bit performance while featuring the essentials of the STM32 family and being particularly suited for cost-sensitive applications. STM32 F0 MCUs combine real-time performance, low-power operation, and the advanced architecture and peripherals of the STM32 platform.
The STM32F030 Value line is highly competitive in traditional 8-bit and 16-bit markets and eliminates the need to manage different architectures and the associated development overhead.
The STM32F0x2 line provides rich connectivity with crystal-less USB 2.0 and with a CAN bus interface, making it the ideal choice for communication gateways, smart-energy devices or game terminals.
The STM32F0x8-line operating at 1.8V +/-8% is well suited for use in portable consumer applications such as smartphones, accessories and media devices.
The STM32 turns the one-architecture-fits-all concept into reality.
Proposed in various package types, the STM32 F0 satisfies the needs of a large variety of applications and segments
