80 MHz Cortex-M4 with 256 KB Flash — what it means for a motor-drive or industrial I/O design
The Infineon XMC4200F64F256BAXQMA1 is a 32-bit ARM Cortex-M4 MCU from the XMC4000 series, clocked at 80 MHz with 256 KB Flash and 40K x 8 RAM. It targets industrial control applications — motor drives, PLC I/O modules, and fieldbus gateways — where the Cortex-M4 DSP and FPU handle real-time control loops and signal conditioning. The 35 I/O pins in a 64-LQFP exposed-pad package keep the board footprint compact for space-constrained terminal blocks or drive stages. On-chip peripherals include DMA, PWM, WDT, and a 16-channel 12-bit ADC plus dual 12-bit DAC, covering analog feedback and sensor acquisition without external converters.
