70 ns access — what it buys the bus
The Infineon (Cypress) S29AL016J70FFI010 is a 16 Mbit parallel NOR flash from the AL-J family. Its 70 ns access time sets the read-cycle window for the host controller.
Supply and temperature — where it runs
The 2.7 V minimum means a 3.3 V rail needs a small LDO to drop down — the part is not 3.3 V tolerant on VCC, though the I/O levels follow the supply.
Package reality — 64-ball FBGA
The 64-ball Fine-Pitch BGA (FBGA) package is the only form factor listed. This is a dense, low-profile footprint that saves board area but demands solder-paste stencil design and X-ray inspection for rework. Not a hand-solderable part — factor in assembly capability before committing the BOM. The tray shipping medium is typical for BGA devices at this density.
Lifecycle — still an active line
Official product status is Active. The AL-J series has been a long-running parallel NOR flash family; the active status suggests Infineon intends to support it for the foreseeable future.
