［原创］ST STM32F072 32位ARM MCU开发方案

ST公司的STM32F072是基于ARM® Cortex®-M0内核的32位MCU,CPU工作频率48MHz,集成了128KB闪存,16KB SRAM, 无晶振的USB FS 2.0, CAN,12个定时器,ADC, DAC和通信接口如两个I2C,两个SPI/I2S,一个HDMI CEC和四个USART.工作电压2.0V到3.6 V,主要用在应用控制和用户接口,手持设备,A/V接收器和数子TV,PC外设,游戏和GPS平台,工业应用,PLC,逆变器,打印机,扫描仪,告警系统,视频互连和HVAC.本文介绍了STM32F072主要特性,框图和时钟树, STM32 Nucleo-F072RB板主要特性,电路图和材料清单.

The STM32F072x8/xB microcontrollers incorporate the high-performance ARM® Cortex®-M0 32-bit RISC core operating at up to 48 MHz frequency, high-speed embedded memories (up to 128 Kbytes of Flash memory and 16 Kbytes of SRAM), and an extensive range of enhanced peripherals and I/Os. All devices offer standard communication interfaces (two I2Cs, two SPI/I2S, one HDMI CEC and four USARTs), one USB Full-speed device (crystal-less), one CAN, one 12-bit ADC, one 12-bit DAC with two channels, seven 16-bit timers, one 32-bit timer and an advanced-control PWM timer.

The STM32F072x8/xB microcontrollers operate in the -40 to +85 °C and -40 to +105 °C temperature ranges, from a 2.0 to 3.6 V power supply. A comprehensive set of power-saving modes allows the design of low-power applications.
