STM32F745更好性能 更优势价格
STM32F7 series of very high-performance MCUs with ARM® Cortex®-M7 core
Taking advantage of ST’s ART Accelerator™ as well as an L1 cache, STM32F7 devices deliver the maximum theoretical performance of the Cortex-M7 no matter whether code is executed from embedded Flash or external memory: 1082 CoreMark /462 DMIPS at 216 MHz fCPU.
Smart architecture with new peripheral set
The STM32F7 series unleashes the new Cortex-M7 core:
AXI and multi-AHB bus matrix for interconnecting core, peripherals and memories
Two general-purpose DMA controllers and dedicated DMAs for Ethernet, high-speed USB On-The-Go interface and the Chrom-ART graphic accelerator.
Peripheral speed independent from CPU speed (dual clock support) allowing system clock changes without any impact on peripheral operations
Even more peripherals, such as two serial audio interfaces (SAI) with SPDIF output support, three I2S half-duplex with SPDIF input support, two USB OTG with dedicated power supply and Dual-mode QuadSPI Flash
Large SRAM with a scattered architecture:
320 Kbytes of universal data memory, including 64 Kbytes of Tightly-Coupled Memory for Data (DTCM) for time critical data handling (stack, heap...)
16 Kbytes of Tightly-Coupled Memory for Instructions (ITCM) for time-critical routines
4 Kbytes of backup SRAM to keep data in the lowest power modes
Power efficiency
7 CoreMark / mW at 1.8 V
100 μA typical current consumption in Stop mode with all context and SRAM saved
Compatibility
Cortex-M7 is backwards compatible with the Cortex-M4 instruction set
STM32F7 series is pin-to-pin compatible with the STM32F4 series*
