Cortex?-M7 32位RISC核,集成多达2MB闪存,512KB SRAM,16KB TCM RAM,4KB备份SRAM和各种外设,主要用在马达驱动和工业控制,医疗电子,家用音频设备,可穿戴智能手表,PLC,逆变器和电路中断器,打印机和扫描仪,告警系统,视频连接和HVAC,移动应用和物联网(IoT).本文介绍了STM32F779xx系列主要特性,框图,评估板STM32F779I-EVAL主要特性,框图,电路图,材料清单和PCVB元件布局图.The STM32F777xx, STM32F778Ax and STM32F779xx devices are based on the high-performance ARM? Cortex?-M7 32-bit RISC core operating at up to 216 MHz frequency. The Cortex?-M7 core features a floating point unit (FPU) which supports ARM? double-precision and single-precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances the application security.The STM32F777xx, STM32F778Ax and STM32F779xx devices incorporate high-speed embedded memories with a Flash memory up to 2 Mbytes, 512 Kbytes of SRAM (including 128 Kbytes of Data TCM RAM for critical real-time data), 16 Kbytes of instruction TCM RAM (for critical real-time routines), 4 Kbytes of backup SRAM available in the lowest power modes, and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses, a 32-bit multi-AHB bus matrix and a multi layer AXI interconnect supporting internal and external memories access.All the 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 four I2Cs?? Six SPIs, three I2Ss in half-duplex mode. 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 four UARTs?? An USB OTG full-speed and a USB OTG high-speed with fu
