Core and memory headroom for industrial control
The XMC4400F64K512BAXQMA1: That memory split gives enough headroom for a real-time control loop with a communication stack — the 512 KB Flash holds a moderate application plus a bootloader, while the 80 KB RAM handles the stack and data buffers without spilling to external memory.
A motor drive or PLC module that sees 105°C on a hot factory floor still has 20°C of headroom before hitting the absolute limit. The 3.13V to 3.63V supply range means it runs from a single 3.3V rail — no separate I/O or core supply needed.
Peripheral mix for connectivity and signal chain
On-chip connectivity includes CANbus, Ethernet, I²C, LINbus, SPI, UART, and USB — enough to serve as the main controller in a distributed automation node that talks to a fieldbus gateway (Ethernet) and local sensors (I²C/SPI) simultaneously. The data converter block packs 14 channels of 12-bit ADC and 2 channels of 12-bit DAC, so analog inputs like thermocouple or current-sense signals can be digitised without an external ADC. Additional peripherals include DMA, I²S, LED, POR, PWM, and WDT.
Package and board integration
Housed in a 64-LQFP with an exposed pad (Infineon code PG-LQFP-64-19), the package has 31 usable I/O.
