16 Mbit automotive-grade parallel NOR Flash
The Infineon (formerly Cypress) S29AL016J70TFA020 is a 16 Mbit parallel NOR Flash memory from the AL-J series, organized as 2 M x 8 or 1 M x 16. It operates from a single 2.7 V to 3.6 V supply and provides a 70 ns access time, making it suitable for code shadowing, parameter storage, and firmware updates in embedded systems that require fast random reads. The part is AEC-Q100 qualified (Automotive grade) and rated for the -40 °C to 85 °C industrial temperature range, covering automotive cabin, outdoor telecom, and factory automation environments.
70 ns access time — what it means for the bus
The 70 ns access time is the time from address valid to data valid on the parallel bus. The write cycle time — word and page — is also 70 ns.
AEC-Q100 qualification: what it buys you
The Automotive grade (AEC-Q100) means this part has passed the full suite of stress tests: high-temperature operating life (HTOL), temperature cycling, moisture sensitivity, and ESD robustness. The -40 °C to 85 °C temperature range covers the passenger cabin and most under-hood locations that are not directly engine-mounted.
