128 Mbit SPI NOR Flash — FL-P series
It operates on a 2.7 V to 3.6 V supply rail and communicates over a serial peripheral interface at clock frequencies up to 104 MHz. The memory is non-volatile, formatted as FLASH - NOR, and targets firmware storage, boot code, and configuration data in embedded systems.
104 MHz SPI clock — bus timing margin
The 104 MHz SPI clock rate determines the read throughput and timing budget for the host controller. The 3 ms write cycle time per page means sustained writes are not the part's strength.
