ST STM32F746BGT6

ARM® Cortex®-M7216 МГц1 МБ (1М x 8)

Overview

The STM32F746BGT6 is a STM32F7 series high performance ARM based Cortex-M7 32bit microcontroller in 208 pin LQFP package. This general purpose microcontroller with FPU, adaptive real time accelerator (ART Accelerator) and L1 cache has 32bit RISC core operating at up to 216MHz frequency. The Cortex-M7 core has single floating point unit (SFPU) precision which supports all ARM single precision data processing instructions and data types. It also implements a full set of DSP instructions and memory protection unit (MPU) which enhances the application security. The STM32F746 microcontroller incorporates high speed embedded memories, 1024bytes of OTP memory, an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses, 32bit multi AHB bus matrix and multi layer AXI interconnect supporting internal and external memories access.
