It communicates over a SPI bus with Quad I/O and QPI support, clocked at up to 108 MHz. The 2.7 V to 3.6 V supply range and -40°C to 105°C operating temperature make it suitable for industrial controls, outdoor telecom, and automotive body electronics where the board sees extended thermal cycling. The 24-ball BGA (8x6 mm body) saves PCB area compared to a wider SOIC or WSON package, but the BGA footprint needs careful routing — the ball pitch and via capture pad must match your fab's minimum annular ring.
108 MHz clock and Quad I/O — what the bus timing means
The 108 MHz clock rate with Quad I/O mode supports execute-in-place (XIP) code shadowing for a Cortex-M or RISC-V MCU.
For new designs, the FL-L series is the current mainstream NOR flash family from Infineon (formerly Cypress), so PCN risk is low.
