The Cortex-M7 core features a single floating point unit (SFPU) precision which supports all ARMsingle-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 STM32F756xx devices incorporate high-speed embedded memories with Flash memory up to 1 Mbyte, 320 Kbytes of SRAM (including 64 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 devices offer three 12-bit ADCs, two DACs, a low-power RTC, thirteen general-purpose 16-bit timers including two PWM timers for motor control and one low-power timer available in Stop mode, 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.STM32F756xx系列主要特性:Core: ARM 32-bit Cortex-M7 CPU with FPU, adaptive real-time accelerator (ART Accelerator) and L1-cache: 4KB data cache and 4KB instruction cache, allowing 0-wait state execution from embedded Flash memory and external memories, frequency up to 216 MHz, MPU, 462 DMIPS/2.14 DMIPS/MHz (Dhrystone 2.1), and DSP instructions.MemoriesUp to 1MB of Flash memory1024 bytes of OTP memorySRAM: 320KB (including 64KB of data TCM RAM for critical real time data) + 16KB of instruction TCM RAM (for critical real time routines) + 4KB of backup SRAM (available in the lowest power modes)Flexible external memory controller with up to 32-bit data bus: SRAM, PSRAM, SDRAM/LPSDR SDRAM, NOR/NAND memoriesDual mode Quad-SPILCD parallel interface, 8080/6800 modesLCD-TFT controller up to XGA resolution with dedicated Chrom-ART Accelerator for enhanced graphic content creation (DMA2D)Clock, reset and supply management1.7 V to 3.6 V application supply and I/OsPOR, PDR, PVD and BORDedicated USB power4-to-26 MHz crystal oscillatorInternal 16 MHz factory-trimmed RC (1% accuracy)32 kHz oscillator for RTC with calibrationInternal 32 kHz RC with calibrationLow-powerSleep, Stop and Standby modesVBATsupply for RTC, 3232 bit backup registers + 4KB backup SRAM312-bit,2.4 MSPS ADC: up to 24 channels and 7.2 MSPS in triple interleaved mode212-bit D/A convertersUp to 18 timers: up to thirteen 16-bit (1x low- power 16-bit timer available in Stop mode) and two 32-bit timers, each with up to 4 IC/OC/PWM or pulse counter and quadrature (incremental) encoder input.
