Flash sector sizes

Hi All


I am trying to work out the FLASH sectors sizes in all of the Kinetis parts.


What I know is:

- The 100MHz 512k parts have 2k Flash sector size and use the long word programming command when writing

- The 120MHz FPU 1M parts have 4k Flash sector size and don't support the long word programming command but instead the "phrase" programming command (8 bytes)


However I don't find the sector size specified in either the user manual or the data sheets (apart from some timing which have 4k in brackets which is probably pointing out that the is the sector size that the timing refers to).


Unsure is whether FPU devices with smaller Flash sizes use 2k or 4k sectors. Or whether non-FPU types with 1M (if they exist) will have 2k or 4k?


Anyone know the details?
