ST公司的STM32F072xx系列是基于ARM® Cortex®-M0 32位RISC内核的MCU,工作频率48MHz,多达128KB闪存和16KB SRAM的高速嵌入存储器,提供标准通信接口如两个I2C, 两个SPI/一个I2S, 一个HDMI CEC和四个USART,一个USB全速器件接口,一个CAN,一个12位ADC和DAC,7个通用16位计时器,一个32位计时器和PWM计时器.主要用在手持设备,工业应用,逆变器,HVAC,数字电视,DTV,PLC,GPS平台,视频连接,告警系统,打印机,扫描仪,PC外设等.本文介绍了STM32F072xx系列主要特性,框图和时钟树,以及STM32F072 Discovery板32F072BDISCOVERY,硬件框图,电路图,PCB元件分布图和材料清单.
The STM32F072xx microcontrollers incorporate the high-performance ARM® Cortex®-M0 32-bit RISC core operating at a 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 SPIs/one 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 general-purpose 16-bit timers, a 32-bit timer and an advanced-control PWM timer.
The STM32F072xx microcontrollers operate in the -40 to +85 ℃ and -40 to +105 ℃ 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.
