Package and board integration
The S29AL008J55TFIR20: Housed in a 48-TFSOP (0.724", 18.40mm width) package, the device is surface-mount with the supplier device package designated as 48-TSOP — a standard footprint for parallel NOR Flash in embedded designs. The 55 ns write cycle time (word/page) matches the read access, allowing symmetric bus timing for firmware update routines that erase and reprogram sectors in-system.
Sourcing and procurement posture
No pin-compatible second-source or direct successor is recorded in the AL-J series — the BOM position should be qualified against this specific order code.
