The 112 I/O lines in a 144-LQFP package give plenty of headroom for parallel buses or dense peripheral interfaces without stepping to a BGA footprint. ## 144-LQFP: rework-friendly, inspectable, no BGA complexity The 144-LQFP package with a 20x20 mm body is a standard QFP — every pin is visible and probeable.
