8 Mbit parallel NOR Flash for industrial code storage
The Infineon S29AL008J70BFI013 is an 8 Mbit parallel NOR Flash memory from the AL-J series, organized as 1 M x 8 or 512 K x 16. It runs on a 2.7 V to 3.6 V supply and delivers a 70 ns access time, making it a direct fit for 8/16-bit microcontroller and ASIC buses that need fast, random-access code execution or data storage. The -40°C to 85°C industrial temperature range suits it for motor drives, outdoor telecom, factory automation, and other environments where the board sees thermal cycling.
70 ns access time — what it means for the bus
The 70 ns access time is the time from address assertion to valid data on the output. The parallel interface eliminates serial protocol overhead.
Package and footprint
The 48-ball VFBGA (8.15 x 6.15 mm) is a fine-pitch BGA. It saves board area compared to a TSOP-48, but requires a multi-layer PCB with microvias or blind vias for fan-out.
