32 Mbit parallel NOR Flash in a 48-TSOP footprint
The Infineon S29JL032J70TFI423 is a 32 Mbit parallel NOR Flash memory from the JL-J series. It organizes as 4M x 8 or 2M x 16, accessed through a parallel interface with a 70 ns access time.
70 ns access — timing margin for the bus
The 70 ns access time sets the read-cycle window for the host controller. The write cycle time per word or page is also 70 ns.
Active lifecycle — no LTB risk for new designs
The S29JL032J70TFI423 carries an Active product status. That means the manufacturer continues to produce it, and there is no announced last-time-buy or phase-out window. For a BOM line, this part can be specified into new production without planning a lifetime buy or a qualification of a replacement. The part is ROHS3 compliant.
