178 I/O in a 256-FBGA — routing and board fit
The 256-FBGA (17x17 mm) package routes 178 I/O to the board. That pin density suits four-layer PCBs with blind vias; two-layer designs will need careful fan-out planning. The commercial temperature range (0°C to 85°C junction) limits deployment to indoor, conditioned environments — not for engine bays or outdoor telecom cabinets without active cooling.
