High-performance MCUs offer maximum theoretical performance of the Cortex-M7
The STM32F7 series of high-performance MCUs with ARM Cortex-M7 core is now
available from Farnell element14. The device takes advantage of
STMicroelectronics' ART Accelerator as well as an L1 cache to deliver the
maximum theoretical performance of the Cortex-M7, says the company.
This superlative performance is achieved regardless of whether the code is
executed from embedded Flash or external memory: 1082 CoreMark /462 DMIPS at
216 MHz fCPU. The STM32F7 is fully pin-to-pin and code compatible with the
STM32F4 and the STM32 ecosystem, allowing for easy upgrade of existing
System performance is optimised by combining brand-new peripherals around
the Cortex-M7 with a superior interconnect architecture featuring AXI and
multi AHB bus matrix, multiple DMA and the Chrom-ART Accelerator hardware.
This enables concurrent high-speed data transfers between bus masters and
slaves without overworking the CPU.
The large SRAM with overloading architecture provides support for large data
buffers, critical real-time data routines and backup. It consists of 320
Kbytes, including 64Kbytes of Data TCM RAM; 16 Kbytes of instruction TCM RAM
and 4Kbytes of backup SRAM.
New peripheral sets include two SAI (with SPDIF outport support), three 12S
half-duplex and SPDID input, enabling multiple audio channel I/O support; 2x
USB OTG with dedicated power supplies, supporting USB communication even
when the MCU is powered at 1.8V; dual QuadSPI interface to connect
cost-effective memories with 1, 4 or 8 data pins, says the company.
