states. Therefore, it is recommended that each flash block orsector be re-erased immediately prior to factory programmingto ensure that the full data retention capability is achieved.32.2.1 FeaturesThe FTFC module includes the following features.NOTESee the device's Chip Configuration details for the exactamount of flash memory available on your device.32.2.1.1 Program flash memory features• Sector size of 2 KB for non-interleaved configurations (i.e., 256 KB and less). 4 KBfor interleaved configurations (512 KB and greater)• Program flash protection scheme prevents accidental program or erase of stored data• Automated, built-in, program and erase algorithms with verify• Section programming for faster bulk programming times• Read access to the program flash block is possible while programming or erasingdata in the data flash block or FlexRAM32.2.1.2 FlexNVM memory featuresWhen FlexNVM is partitioned for data flash memory:• Sector size of 2 KB for non-interleaved configurations (i.e., all configurations otherthan the 2 MB configuration). 4 KB for interleaved configurations (2 MB)• Protection scheme prevents accidental program or erase of stored data• Automated, built-in program and erase algorithms with verify• Section programming for faster bulk programming times• Read access to the data flash block possible while programming or erasing data in theprogram flash block32.2.1.3 FlexRAM features• Memory that can be used as traditional RAM or as high-endurance emulatedEEPROM storage• Up to 4 KB of FlexRAM configured for emulated EEPROM or traditional RAMoperationsChapter 32 Flash Memory Module (FTFC)MWCT101xS Series Reference Manual, Rev. 3, 07/2019NXP Semiconductors 711
