Obsolete — plan the replacement now
Cypress (now Infineon) has discontinued the FL-P series. The exact successor order code depends on density and temperature grade; confirm the cross-reference against your specific firmware image size and operating temperature requirement.
Write-cycle timing and endurance
Page program time is 3 ms typical, word program 5 µs typical. These are the numbers to budget for OTA update or field-reprogramming windows. NOR Flash endurance is typically rated at 100,000 erase cycles per sector — the FL-P family follows that norm, so wear-leveling in the filesystem layer is advisable if the device logs configuration data frequently.
