The Infineon S29AL016J70BFI023 is a 16 Mbit parallel NOR Flash memory from the AL-J series, organized as 2M x 8 or 1M x 16. It delivers a 70 ns access time across the full -40°C to 85°C industrial temperature range, operates from a 2.7 V to 3.6 V supply, and comes in a 48-VFBGA package (8.15 x 6.15 mm footprint). This is the part you reach for when you need a moderate-density code-storage or parameter-logging NOR Flash on a parallel bus — common in industrial controllers, telecom line cards, and embedded systems where the host MCU or FPGA has a parallel memory interface and the firmware image fits within 16 Mbit.
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 pins. The write cycle time is also 70 ns for word and page writes.
16 Mbit density — the BOM-fit tier
16 Mbit (2 MB) is organized as 2M x 8 or 1M x 16.
