The STM32F030x4/6/8/C microcontrollers incorporate the high-performance ARMCortex-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.

价格呢？？价格很关键，，没价格就没有参考意义了！！ 我有一个产品正在开发，供应商就是用的这个芯片，楼主能提供一下价格作为参考吗？ laujc 发表于 2017-1-11 16:39

听说要1.5美元，具体价格看量吧。 iwqt1983 发表于 2017-1-19 09:17

不客气，我也这看好这个STM32F030CCT6，因为它有 6个Uart，32KB RAM,256KB Flash，适合跑UCOS等小型操作。
有问题在此一块交流。 比103C8贵不少啊！！ 本帖最后由 iwqt1983 于 2017-1-19 12:34 编辑

比103C8贵不少啊！！
是贵点，可是存储器大不少啊。32KB的RAM，256KB的FLash。
并且带6个串口，
并且的6个串口扩展芯片进口的都要1美元了吧。别说这是个微控制器了，这样来看这不算贵的。 实时操作系统太耗费RAM了。

是的，这STM32F030CCT6 的RAM是32KB，
而其他的STM32F030系列的存储器最大也就8KB，所以要跑小系统要用STM32F030CCT6 ，
并且它有6个串口，方便通讯，串口6个都支持DMA直接数据通道。
http://club.szlcsc.com/article/details_1273_0_1_0_1_1.html 刚刚查看了这个030CCT6，本来想用一下的，结果却郁闷地发现，这个芯片居然没有Vbat的引脚，变成了Vdd，分明就是不想让人用RTC嘛，而且备份的RAM也是木有的，放弃了，换072，虽然USB,CAN用不上。 iwqt1983 发表于 2017-1-19 11:21

STM32F030CC需有6串口,但能同时使能DMA吗 就是主频低了点，DMA才5通道
