128 Mbit NOR Flash for automotive and industrial
It uses a SPI interface with Quad I/O and QPI support, clocked at 133 MHz for fast read throughput. The 16-SOIC (7.50 mm width) surface-mount package suits automated assembly lines for automotive ECUs, ADAS modules, and telematics control units where non-volatile code and data storage must survive under-hood thermal cycling.
The FL-L series designation also indicates the part is built on Infineon's MirrorBit technology, which provides the endurance and data retention expected for 15+ year automotive service life.
133 MHz Quad SPI — throughput and pin savings
The SPI interface supports standard single, dual, quad I/O, and QPI (Quad Peripheral Interface) protocols. At 133 MHz in Quad I/O mode, the effective read throughput reaches 532 Mbps, sufficient for fast boot and XIP (eXecute-In-Place) code shadowing in real-time systems. The four data pins keep the PCB routing simple compared to parallel NOR alternatives, saving board area and reducing layer count in dense automotive designs. QPI mode further simplifies by using the same four pins for address and data, useful when the host controller supports it natively.
Storage temperature exceeds this range, but that is a handling limit, not an operating condition.
Franchised distribution channels carry this part, and independent distribution also holds traceable excess from overruns and cancelled programs.
