Product details

It targets applications that need both compute throughput and large on-chip memory — think graphics-capable HMI panels, multi-protocol IoT gateways, or sensor fusion nodes running floating-point algorithms. 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.

Listed as Active in the product status.
