256 Mbit parallel NOR Flash for industrial code storage
The Infineon S29GL256P11FAI010 is a 256 Mbit parallel NOR Flash from the GL-P series, organized as 16M x 16 bits. It uses a CFI (Common Flash Interface) for parameter identification, which simplifies driver portability across density variants. With a 110 ns random access time and a 2.7 V supply, this part is sized for single-rail 3.3 V embedded systems that need fast read for code shadowing or XIP (eXecute In Place) in industrial controllers, networking gear, and telecom line cards.
For a 16-bit wide bus, this delivers about 18 MB/s sequential read throughput. That is fast enough for boot code and moderate-speed data logging, but if your design needs back-to-back burst reads at higher clock rates, you may want to budget wait states or look at a page-mode variant. The 110 ns write cycle time (word or page) also applies, so page programming can reduce per-byte write time when updating firmware blocks.
The 64-ball FBGA package is a fine-pitch BGA (0.8 mm ball pitch typical for this family) — plan for controlled impedance routing and a solder mask defined pad. No exposed thermal pad; dissipation is through the BGA balls and PCB copper.
