The BGA 254 package is designed to support high-density and high-performance applications. It offers a compact footprint with a large number of I/Os (inputs/outputs), making it suitable for complex integrated circuits.
Necessary for developers writing drivers to ensure data is latched correctly during read/write cycles.
VSS pins are distributed throughout the grid to ensure signal integrity. 2. Physical and Land Pattern Dimensions
But Aris had found, through a blown capacitor and a near-miss with a fire extinguisher, that D13 was connected. It was connected to a dormant test routine left over from the factory. A routine that, if triggered by the right 1.8V pulse, could make the chip do something impossible: process a quantum hash faster than light.
On page 42, footnote 3, it said: "Pin D13 is not connected (N/C)."
