ST STM32F415ZG双马达磁场定向控制(FOC)开发方案

ST公司的STM32F415xx和STM32F417xx系列是基于高性能ARM®Cortex™-M4 32位RISC核的32位MCU,工作频率高达168MHz,具有210 DMIPS/ 1.25 DMIPS/MHz (Dhrystone 2.1)性能和DSP指令,多达1MB闪存/192+4KB RAM,加密, USB OTG HS/FS，以太网等.主要用在马车驱动和控制,医疗设备,工业设备如PLC,逆变器,打印机和扫描仪,家庭音频设备以及HVAC和视频连接等.本文介绍了STM32F41x 系列主要特性和框图, 演示板STEVAL-IHM039V1主要特性,电路图和材料清单.
The STM32F415xx and STM32F417xx family is based on the high-performance ARM®Cortex™-M4 32-bit RISC core operating at a frequency of up to 168 MHz. The Cortex-M4 core features a Floating point unit (FPU) single precision which supports all ARM singleprecision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security. The Cortex-M4 core with FPU will be referred to as Cortex-M4F throughout this document.
The STM32F415xx and STM32F417xx family incorporates high-speed embedded memories (Flash memory up to 1 Mbyte, up to 192 Kbytes of SRAM), up to 4 Kbytes of backup SRAM, and an extensive range of enhanced I/Os and peripherals connected to two APB buses, three AHB buses and a 32-bit multi-AHB bus matrix.
All devices offer three 12-bit ADCs, two DACs, a low-power RTC, twelve general-purpose 16-bit timers including two PWM timers for motor control, two general-purpose 32-bit timers, a true random number generator (RNG), and a cryptographic acceleration cell. They also feature standard and advanced communication interfaces.
• Up to three I2Cs
• Three SPIs, two I2Ss full duplex. To achieve audio class accuracy, the I2S peripherals can be clocked via a dedicated internal audio PLL or via an external clock to allow synchronization.
• Four USARTs plus two UARTs
• An USB OTG full-speed and a USB OTG high-speed with full-speed capability (with the ULPI),
• Two CANs
• An SDIO/MMC interface
