It supports 2-wire capacitive touch sensing and communicates over I²C or SPI, making it suitable for medium-to-large format touch panels in industrial HMI, medical, and point-of-sale terminals. ## Supply rails and temperature range for the BOM engineer The device requires two supply rails: a core supply from 1.71V to 3.47V and a touch/IO supply from 3.14V to 3.47V — both must be present for proper operation. Typical supply current is 40 mA, which sets the LDO or regulator sizing for the touch controller rail. ## 88-UFBGA footprint and board integration The 88-ball UFBGA package with 0.5 mm ball pitch demands a 4-layer PCB for fan-out — the inner rows require micro-vias or blind vias to escape to inner layers. Supplier device package is 88-UFBGA (6x6 mm), which is the same footprint used across the maXTouch U family for drop-in compatibility when scaling node count. ## Active lifecycle and compliance posture RoHS3 compliant with no exemptions noted, meeting EU and global regulatory requirements for lead-free assembly.","metaTitle":"Microchip ATMXT448UD-CCUBHA1 Touchscreen Controller","metaDescription":"Active-production 448-node capacitive touchscreen controller IC.
