ST STM32F37x 32位Cortex－M4F MCU开发方案
ST公司的STM32F37x系列产品是高性能ARM Cortex-M4F 32位RISC MCU,工作频率高达72MHz,嵌入浮点单元(FPU),存储器保护单元(MPU)和嵌入式跟踪宏单元(ETM),嵌入式闪存高达256KB,SRAM高达32KB,工作电压2.0 到3.6 V,主要用在移动游戏,增强现实感,光学图像稳定性,手持导航,机器人和工业自动化系统.本文介绍了STM32F37x系列主要特性,框图,STM32F3DISCOVERY开发板主要特性,硬件框图,电路图和开发板布局图.
The STM32F37x family is based on the high-performance ARM® Cortex™-M4F 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 Kbyte of Flash memory, up to 32 Kbytes of SRAM), and an extensive range of enhanced I/Os and peripherals connected to two APB buses.
The STM32F37x devices offer one fast 12-bit ADC (1 Msps), up to three 16-bit Sigma delta ADCs, up to two Comparators, up to two DACs (DAC1 with 2 channels and DAC2 with 1 channel), a low-power RTC, 9 general-purpose 16-bit timers, two general-purpose 32-bit timers, three basic timers.
They also feature standard and advanced communication interfaces: up to two I2Cs, three SPIs, all with muxed I2Ss, three USARTs, CAN and USB.
