The Infineon XMC4800F100F1024AAXQMA1 is a 32-bit ARM Cortex-M4 microcontroller running at 144 MHz, with 1 MB of Flash program memory and 200K x 8 of RAM. It sits in the XMC4000 series, Infineon's industrial-focused MCU line built for real-time control and multi-protocol connectivity. On-chip peripherals include DMA, I²S, LED drive, POR, touch-sense, and WDT, while the connectivity block covers CANbus, EBI/EMI, Ethernet, I²C, LINbus, MMC/SD, SPI, UART/USART, USB OTG, and USIC — enough to serve as a single-chip node in factory automation, motor control, or building-management gateways.
144 MHz Cortex-M4 — what that means for a control loop
At 144 MHz, this core can close a current-control loop in a servo drive or run a Modbus TCP stack without a separate communications processor. The 1 MB Flash holds a full application image plus a bootloader for field updates.
Analog front-end integration
The 24-channel 12-bit ADC and dual 12-bit DAC handle sensor acquisition and analog output in a motor-drive or PLC analog I/O card without an external converter. The 75 general-purpose I/O, mapped to the 100-LQFP Exposed Pad package (PG-LQFP-100-25), provide enough pins for a parallel LCD interface or a bank of isolated digital inputs. Supply range is 3.13 V to 3.63 V.
The industrial temperature range means the crystal oscillator and Flash retention are characterised across the full span.
