The Spansion FM4 family of 32-bit, general-purpose MCUs covers the highest end of the product range. Based on the ARM® Cortex®-M4F processor core, the family features DSP and Floating Point Unit (FPU) functions.
These MCUs are designed for applications that require advanced, high-speed computing performance such as general-purpose inverters, servomotors, "industry 4.0" factory automation, PLCs and other industrial equipment, as well as medical and surveillance products, and inverter-based home appliances such as washing machines and air conditioners.
TFT based HMI systems can be realized in a very efficient way using the FM4 derivatives with embedded 2D hardware graphics accelerator and VRAM. FM4 MCUs are also serving as WiFi co-processors enabling high end IoT devices and enable smart metering by handling over-the-air firmware updates.
Simple voice command control capability can be incorporated into products using the FM4 derivatives featuring Spansion’s on-chip voice command firmware.
