STM32F030F4
Mainstream ARM Cortex-M0 Value line MCU with 16 Kbytes Flash, 48 MHz CPU
STM32F030F4供应商：拍明芯城
The STM32F030x4/x6/x8/xC 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/x6/x8/xC microcontrollers operate in the -40 to +85 °C temperature range from a 2.4 to 3.6V power supply. A comprehensive set of power-saving modes allows the design of low-power applications.
The STM32F030x4/x6/x8/xC 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/x6/x8/xC peripherals proposed.
These features make the STM32F030x4/x6/x8/xC 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.

同为一个公司的，同为 cortex-M0内核的cpu；开发过程（外设编程）几乎完全一样；查看区别需要对比 datasheet，每个型号资源都不一样的；内核一样，外设不一样。
【STM32】
STM32系列基于专为要求高性能、低成本、低功耗的嵌入式应用专门设计的ARM Cortex-0内核（ST's product portfolio contains a comprehensive range of microcontrollers, from robust, low-cost 8-bit MCUs 亚吃义础成倍up to 32-bit ARM-based Cortex®-M0 and M0+, Cortex®-M3, Cortex®-M4 Flash microcontro项矛铁省米化号歌察米事llers with a great choice of peripherals.

其中STM32F1系列有：
STM32F10和造失越棉长杨3“增强型”系列
STM32F散种101“基本型”系列
STM盾宜32F105、STM32F107“互联经立否限云型”系列
增强型系列时钟频率达到72MHz，是同类产品蛋相部陈部烧议造击聚中性能最高的产品；基本型时钟频率为36MHz，以16位产品的价格得到比16位产品大幅提升的性能，是32位产品用户的最佳选择。两个系列都内置32K到128K的闪存，不同的是SRAM的最大容量和外设接口的组合。时先露径钟频率72MHz时，从闪存执行代码，STM32功耗36mA，是32位市场上功耗最低的产品，相当于0.5mA敌印/MHz。
什么叫做单片机，单片机的特点
单片机是一种集成在电路芯片，是采用超大规模集成电路技术把具有数据处理能力的中央处理器CPU随机存储器RAM、只读存储器ROM、多种I/O口和中断系统、定时器/计时器等功能（可能还包括显示驱动电路、脉宽调制电路、模拟多路转换器、A/D转换器等电路）集成到一块硅片上构成的一个小而完善的计算机系统。
