16 Mbit parallel NOR flash — access time and memory organization
The S29AL016J70TFI010 is a 16 Mbit parallel NOR flash from Infineon's AL-J series, organized as 2M x 8 or 1M x 16 bits. The 70 ns access time sets the read-cycle ceiling for the host bus — the memory controller must meet this window to avoid wait-state insertion on every fetch.
Package and board-fit — 48-TSOP footprint
Supplied in a 48-TFSOP package (0.724-inch body width, 18.40 mm) with surface-mount termination. The supplier device package is 48-TSOP — the same mechanical outline as the JEDEC MO-142 standard TSOP type I. The 0.50 mm pin pitch demands a controlled-impedance layout on a multi-layer board for signal integrity on the parallel bus. The write cycle time — 70 ns for word and page programming — matches the read access, so the bus timing is symmetric. Page-mode writes reduce the per-byte programming overhead when the host fills sequential addresses.
ROHS3 compliant (EU 2015/863) — no restricted substances above the threshold limits. The part ships in tray packaging, typical for volume assembly pick-and-place.
