It clocks up to 104 MHz over the SPI interface.
Obsolete — sourcing reality for this BOM line
This part is officially obsolete per the manufacturer. That means no last-time-buy window remains, and the only channel is the surplus and broker market. If this part is on your BOM, you are looking at a one-time buy from independent distribution — not a replenishable line. For a production design, the practical move is to identify a drop-in replacement or re-spin the board for a current-generation SPI NOR Flash.
104 MHz SPI — bus margin and layout note
At 104 MHz the SPI clock edge is fast enough that signal integrity on the PCB trace matters. Keep the clock line short, match trace lengths between clock and data.
