Datasheet

The STM32F7 series 32-bit microcontrollers and the STM32F746G Discovery Kit from ST Microelectronics are now being shipped by distributor Mouser Electronics. With ART Accelerator as well as an L1 cache, the microcontrollers deliver the maximum theoretical performance of the ARM Cortex‑M7, whether code is executed from embedded Flash or external memory.

The Discovery Kit provides an easy‑to‑use development platform for the microcontrollers, and comes with the STM32Cube software tool and a full set of demo software libraries for reduced development efforts, time, and cost.

The devices’ floating point unit (FPU) supports all ARM single-precision data-processing instructions and data types. They feature up to 1MByte of Flash, 320KB of SRAM (including 64KB of data TCM RAM), three 12‑bit analogue-to-digital converters (ADCs), and two digital-to-analogue converters (DACs). Interface options include USART, I²C, SPI/I²S, USB OTG FS, HS, CAN, and SD/MMC.

The Discovery Kit includes an onboard LCD-TFT display with capacitive touch screen and Arduino Uno Rev3 connectors, enabling beginners and experienced developers to quickly get started developing applications for the microcontrollers.The full range of hardware features on the board helps designers to evaluate almost all of the microcontroller’s peripherals, including MEMs digital microphones, SPDIF RCA input, and the 4.3in colour LCD-TFT screen.

The board also features two micro-USB jacks, MicroSD card connector, RJ45 connector, and 3.5mm audio input and output. The integrated ST-LINK/V2-1 via mini-USB connector provides an embedded in-circuit debugger and programmer for the STM32F746 microcontroller. The board also supports software development with ARM mbed.

The features of the STM32F746G Discovery Kit make it ideal for home audio, motor control, security and Internet of Things (IoT) applications.
