What this part is and where it fits
The Infineon XMC1404Q064X0200AAXUMA1 is a 32-bit ARM Cortex-M0 microcontroller from the XMC1000 series, clocked at 48 MHz with 200 KB of Flash program memory and 16 KB of RAM. It is built for industrial control, motor drive, and automotive-adjacent applications where the wide supply range (1.8 V to 5.5 V) and extended temperature grade (-40°C to 105°C) cover outdoor telecom cabinets, factory-floor controllers, and engine-bay electronics. The exposed-pad package (PG-VQFN-64-6) keeps the footprint compact while the exposed pad aids thermal dissipation in power-switching designs.
Key features and what they mean for the BOM
The 48 MHz Cortex-M0 core delivers enough throughput for real-time control loops — think sensor polling, PWM generation, and CAN message handling — without the power budget of a Cortex-M4. The 200 KB Flash is sized for moderate firmware stacks including bootloader, communication protocol stacks, and application code; the 16 KB RAM supports a few hundred bytes of data buffer plus stack and variables, but if your application needs large frame buffers or extensive lookup tables, plan for external SRAM or a part with more RAM. Connectivity includes CANbus, LINbus, I²C, SPI, and UART/USART — the CAN and LIN interfaces make this a natural fit for automotive sub-systems (body control, lighting, sensor nodes) and industrial fieldbus gateways. The 12-channel 12-bit ADC captures analog sensor feedback for motor current sensing or temperature monitoring. On-chip peripherals like PWM, watchdog timer, brown-out detect, and POR reduce external glue logic, saving board space and BOM cost.
Lifecycle and sourcing posture
This part carries an Active lifecycle status with ROHS3 compliance. No last-time-buy or end-of-life notices are in effect, so it is safe to specify for new designs and production BOMs.
