STM32 32位ARM Cortex MCUThe STM32 family of 32-bit Flash microcontrollers based on the ARM® Cortex®-M processor is designed to offer new degrees of freedom to MCU users. It offers a 32-bit product range that combines very high performance, real-time capabilities, digital signal processing, and low-power, low-voltage operation, while maintaining full integration and ease of development.The unparalleled and large range of STM32 devices, based on an industry-standard core and accompanied by a vast choice of tools and software, makes this family of products the ideal choice, both for small projects and for entire platform decisions.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 STM32F0x1 line provides a high integration of functions and covers a wide range of memory size and packages, bringing flexibility to cost-sensitive applications.∙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.STM32F030 超值系列STM32F030采用ARM Cortex内核，运算速度高达48 MHz。

该组合轻松超越了现有的8位架构，让所有应用设计者均能得益于先进32位内核的简单性和高效率。
STM32F030超值系列提供多种存储容量和引脚数组合，能与之匹敌的器件少之又少，从而进一步优化项目成本。
采用STM32F030的应用设计者能够随时升级到功能强大的STM32系列中的任何产品，并且工具和应用软件的可重用性极高。
STM32F0x1STM32 F0x1 offers better user experience with high integrationSTM32F0x1 devices are intended for 8- and 16-bit applications where 32-bit performances are required such as home-entertainment products, appliances and industrial equipment. The portfolio covers from 16 to 256 Kbytes of on-chip Flash memory, up to 32 Kbytes of SRAM, and several communication interfaces including USART, SPI, I²C, HMDI CEC and 16-bit PWM motor control timer. The package offer covers from 20- to 100-pin packages.The latest addition to ST’s STM32 F0x1 series, the STM32F091, comes with up to eight USARTs among versatile packages from 48- to 100-pin, including low-thickness WLCSP and BGA variants. Its 256Kbytes on-chip Flash memory and 32 Kbytes SRAM allow Java stack implementation, and the CAN 2.0a/b brings further communication capability for industrial or in-car audio applications.STM32F0x2无晶振USB 2.0 FS拓展了STM32 F0系列，具有高达128 KB的闪存及16 KB的SRAM这些新型STM32 F0器件提供了具有链路层电源管理（LPM）功能的USB 2.0 FS接口，兼容电池充电检测（BCD）规范1.2版本，且无需由外部晶振生成精确时钟也可正常运行USB应用。
通过集成CAN、USART、I²C、SPI (I²S)及HDMI CEC，新型STM32 F0器件使得产品开发者能够提高系统集成度，降低成本，突破旧式专用8位或16位微控制器在USB器件或USB控制器应用上的性价比限制。
STM32F072系列提供了64到128 KB闪存，采用48、64或100引脚封装。
STM32F042系列提供16到32 KB闪存，采用20、28、32和48引脚封装。
STM32F0x8The STM32F0x8 line operates at 1.8V +/-8%. It is well suited to use in portable consumer applications such as smartphones, accessories and media devices, and allows designers to take advantage of the same features as the STM32F0 series with no compromise or degradation in processing performance when operating at lower voltage.The combination of 1.8V digital supply voltage, a separate I/O voltage supply rail and an independent analog domain is an advantage in heterogeneous system architectures, leading to simplified system design and connected cost savings. The STM32F0x8 devices are ideal low-voltage companion microcontrollers, allowing to maintain a wide analog dynamic range or to directly connect USB devices.STM32F1 系列STM32 F1系列主流MCUSTM32 F1系列主流MCU满足了工业、医疗和消费类市场的各种应用需求。
