It communicates over I²C or SPI and draws 40 mA from a supply that can be as low as 1.71 V on the core side or 3.14 V on the touch side. Housed in an 88-ball UFBGA measuring 6x6 mm, this package is a challenge for hand-soldering — you'll want a stencil and a reflow profile, not an iron. The 0.5 mm ball pitch means the PCB layout needs careful fan-out; a four-layer board with microvias is the practical minimum for routing all signals.","metaTitle":"ATMXT640UD-CCUBHA1 Microchip Touchscreen Controller","metaDescription":"Microchip ATMXT640UD-CCUBHA1 capacitive touchscreen controller, 2-wire, I²C/SPI, 1.71V-3.47V, -40°C to 105°C, 88-UFBGA.
