It uses a SPI interface with Quad I/O and QPI support, clocked at 66 MHz, which gives enough throughput to shadow boot code or stream sensor logs without stalling the host controller. NOR Flash is preferred for execute-in-place (XIP) and reliable code storage because of its fast random-read access and high endurance compared to NAND. The 256 Mbit density fits applications needing a single-chip firmware image plus a config or logging partition — common in industrial controllers, base stations, and automotive telematics units.
The 105°C ceiling means no derating needed for equipment installed near a motor or in a sealed outdoor cabinet that sees solar loading.
Package: 24-TBGA (8x6 mm) — compact footprint for space-constrained boards
The 24-ball BGA package (8 mm x 6 mm body) saves board area versus a traditional SOIC or TSOP. It is surface-mount, so it flows through standard reflow without manual handling. The small footprint is a good fit for multi-layer PCBs where the NOR Flash sits alongside the main SoC or MCU on a tight layout.
Active lifecycle — no last-time-buy risk for production builds
The FL-L series is a mature, widely socketed NOR Flash family with multiple density options sharing the same footprint.
