The INX IN518 from a top-down pinout perspective is a systematic QFN-48 device with clear separation of power (left side), I2C/host (top-left), TX drivers (left-to-bottom), RX inputs (bottom-to-right), and analog (right side). Proper layout respects the analog/digital ground split near pin 34 and ensures the charge pump capacitor on pin 36 is placed within 5mm for stable touch sensing.
Design tip: When viewing the IC from the top, always identify the index mark at pin 1 (top-left) before routing – rotating the pinout 90° is the most common assembly error.
