The controller uses 2-wire capacitive mutual-capacitance sensing across 224 nodes, which supports multi-touch and glove-touch operation when the sensor stack-up and overlay thickness are within the tuning range. ## Package, footprint, and temperature grade Housed in a 49-ball UFBGA (5x5 mm body) — the 0.50 mm ball pitch requires a controlled-impedance PCB stack-up with micro-vias or blind vias for fan-out; the exposed center pad (if present) should be connected to the PCB ground plane with thermal vias for heat spreading. Supplied in Bulk (tray) format — the delivery medium is suitable for medium-volume production; for high-volume tape-and-reel, confirm the packing option with the supplier at RFQ.","metaTitle":"Microchip ATMXT224-CCU Touchscreen Controller, 12-bit","metaDescription":"Active-production Microchip ATMXT224-CCU touchscreen controller, 224-node, 12-bit, I²C, 1.71V-3.47V, -40°C to +85°C, 49-UFBGA.
