STM32F415ZG 双马达磁场定向控制(FOC)开发方案

文章来源：更新时间：2014/4/14 14:35:00

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
• Ethernet and the camera interface available on STM32F417xx devices only.

New advanced peripherals include an SDIO, an enhanced flexible static memory control (FSMC) interface (for devices offered in packages of 100 pins and more), a camera interface for CMOS sensors and a cryptographic acceleration cell.

The STM32F415xx and STM32F417xx family operates in the –40 to +105 ℃ temperature range from a 1.8 to 3.6 V power supply. The supply voltage can drop to 1.7 V when the device operates in the 0 to 70 ℃ temperature range using an external power supply supervisor. A comprehensive set of power-saving mode allows the design of low-power applications.

The STM32F415xx and STM32F417xx family offers devices in various packages ranging from 64 pins to 176 pins. The set of included peripherals changes with the device chosen.
