The Cortex-M7 core with single-precision FPU and DSP extensions handles real-time control loops and audio processing without an external DSP. The 1 MB Flash is sized for a full-featured firmware image including a GUI stack, TCP/IP stack, and application logic; the 320 KB SRAM leaves room for double-buffered display frames and packet buffers in Ethernet or USB OTG applications.
The peripheral list includes an LCD interface (listed under Peripherals), supporting parallel TFT-LCD panels. The 320 KB SRAM can serve as a display frame buffer for moderate resolutions.
Both share the same Cortex-M7 core and 1 MB Flash, but the IGK6 variant uses a 176-UFBGA package versus the 176-LQFP of the IGT7. The BGA package offers a smaller footprint (10x10 mm vs 24x24 mm) but requires more complex PCB routing and assembly. The IGT7 in LQFP is easier to hand-solder and inspect, making it the preferred choice for prototyping and medium-volume production.
