STM32F313RC

STM32F3系列微控制器整合了带有DSP与FPU指令、工作频率为72 MHz的32位ARM Cortex-M4内核和高级模拟外设,从而提高了灵活性。 该系列通过整合Cortex-M4内核、快速12位5 MSPS和精密16位sigma-delta ADC、可编程增益放大器(4档增益、精确度为1%)、快速50 ns比较器和工作频率为144 MHz的多功能时钟控制单元实现了嵌入式DSC设计创新,从而实现了最佳集成。
STM32 F3系列让设计者能够解决混合信号控制应用问题。 器件进行了优化,从而能够有效处理三相电机控制器、生化和工业传感器以及音频滤波器等电路的混合信号。 它们有助于简化设计,降低功耗,缩小PCB的尺寸,可广泛用于消费、医疗、便携式健身、系统监控与测量的实际应用。
新型STM32 F3系列与STM32 F1系列引脚兼容,扩大了STM32 Cortex-M4系列产品的阵容,现在ST Cortex-M4家族可提供低成本F3系列的和高性能的F4系列。STM32 F3系列包括带有64~256KB片上Flash存储器和48KB SRAM的器件,提供的封装选项包括WLCSP66(小于4.3 x 4.3 mm)、LQPF48、LQFP64、LQFP100和UFBGA100。

Description

The STM32F313xx family is based on the high-performance ARM® Cortex™-M4 32-bit RISC core operating at a frequency of up to 72 MHz, and embedding a floating point unit (FPU), a memory protection unit (MPU) and an embedded trace macrocell (ETM). The family incorporates high-speed embedded memories (up to 256 Kbytes of Flash memory, up to 48 Kbytes of SRAM), and an extensive range of enhanced I/Os and peripherals connected to two APB buses.

The devices offer up to four fast 12-bit ADCs (5 Msps), up to seven comparators, up to four operational amplifiers, up to two DAC channels, a low-power RTC, up to five general-purpose 16-bit timers, one general-purpose 32-bit timer, and two timers dedicated to motor control. They also feature standard and advanced communication interfaces: up to two I2Cs, up to three SPIs (two SPIs are with multiplexed full-duplex I2Ss on STM32F313xx devices), three USARTs, up to two UARTsand CAN. To achieve audio class accuracy, the I2S peripherals can be clocked via an external PLL.

The STM32F313xx family operates 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 mode allows the design of low-power applications.

The STM32F313xx family offers devices in three packages ranging from 48 pins to 100 pins.

The set of included peripherals changes with the device chosen.
