8Mbit parallel NOR flash in 48-FBGA
The Infineon S29AL008J70BFI022 is an 8Mbit parallel NOR flash from the AL-J series, organized as 1M x 8 or 512K x 16 via a hardware byte-select pin. With a 70 ns access time, this part delivers deterministic read latency suitable for code shadowing or boot storage in embedded systems where the CPU fetches instructions directly from flash. The 48-VFBGA package (8.15 x 6.15 mm body) demands a controlled-impedance layout and a 4-layer board minimum for fan-out of the fine-pitch balls — the 0.50 mm ball pitch is not breakable on two layers without blind vias.
Fully RoHS3 compliant, the part contains no restricted substances above the threshold limits and is suitable for EU-market equipment shipping after 2015.
