Part overview and key ratings
The operating voltage range is 2.7 V to 3.6 V, and the temperature grade is -40°C to 85°C — suitable for industrial environments where the part sits on a PCB inside an enclosure, not under direct engine-bay exposure. The 24-TBGA package (8x6 mm body) requires a reflow profile compatible with BGA soldering, and the mounting is surface-mount only.
64 Mbit density — what it means for firmware storage
64 Mbit (8 MB) of NOR flash. Quad I/O at 104 MHz. Word write time 5 µs, page write time 3 ms.
Where it fits in the system
This flash is typically used as a secondary boot device, configuration store for FPGAs, or code storage for MCUs that lack sufficient internal flash. The SPI interface with Quad I/O minimizes pin count — four data lines plus clock and chip select — so it integrates cleanly into space-constrained designs using a standard MCU SPI peripheral. The industrial temperature range handles outdoor telecom cabinets, factory automation controllers, and base-station line cards without active cooling, as long as ambient stays within -40°C to 85°C.
