STM32F7 Series Microcontrollers, STMicroelectronics

The STM32F7xx microcontrollers are based on the high-performance ARM Cortex-M7 32-bit RISC core.

The STM32F7 microcontrollers feature ST’s ART Accelerator™ as well as an L1 cache and deliver the maximum theoretical performance of the ARM Cortex-M7 core, regardless if code is executed from embedded Flash or external memory. Typical performance figures: 1082 CoreMark / 462 DMIPS at 216MHz clock frequency.

• AXI and multi-AHB bus matrixes for interconnecting core, peripherals and memories
• Double-Precision Floating-Point maths unit on some variants
• Up to 16KB +16KB of I-cache and D-cache
• Up to 2MB of embedded Flash memory, with Read-While-Write capability on certain devices
• Up to 512KB of data memory, including up to 128KB of Tightly-Coupled Memory for Data (DTCM) for Stacks, Heaps
• 16KB of Tightly-Coupled Memory for Instructions (ITCM) for time-critical routines
• 4KB of backup SRAM to keep data in the lowest power modes
• Peripheral speed is independent from CPU speed (dual clock support)
• Protected code execution feature (PC-ROP) on some variants
• Power Efficiency: 7 CoreMark/mW at +1.8Vdc
