64-ball FBGA footprint and board integration
The S29GL128S10FHIV20: Housed in a 64-ball FBGA measuring 13x11 mm, the package requires a 4-layer PCB for fan-out of the fine-pitch balls — the inner layers carry the address/data bus routing while the outer layers handle the supply and ground planes.
Compliance and sourcing posture
Fully ROHS3 compliant — no RoHS exemption expiry risk for designs that need to ship into EU or UKCA markets through the end of the decade.
