216 MHz Cortex-M7 with graphics and connectivity
This is not a low-pin-count part for a sensor node — it is a system-level MCU for boards that replace several discrete controllers.
Memory and data converters for mixed-signal designs
With 24 analog inputs feeding 12-bit ADCs and two 12-bit DACs, the STM32F746IGT6 can handle multi-channel sensor acquisition alongside its control tasks. The 320 KB SRAM is organised as 320K x 8, which maps to a 320 KB contiguous block — enough for a double frame buffer at QVGA resolution or a moderate-size FFT buffer.
