The flash provides the C90TFS Flash driver of Kinetis devices with the C90TFS Flash module inside. The
flash provides general APIs to handle specific operations on C90TFS/FTFx Flash module.
I find references like this scattered in the API docs and source files. Based on context and some Googling my best guess is that TFS is thin film storage and the C90 part means that it's a 90nm process. Is this so well-known that it doesn't need to be defined? Google comes up with fewer than 700 hits, most of them in other languages or duplicates. I've never seen it referenced in any of the device reference manuals. Constantly coming across things like this makes me wonder if there's some cache of NXP/Freescale documentation I'm supposed to know about but I've somehow never seen.

Hi, Scott,
You are right, the C90TFS means that innovative 90nm thin film storage
(TFS) flash process technology is used, the flash technology is used in Kinetis family, latest DSC family, S32K... . Because the technology is confidential, we have not enough documentation. But the reference manual has a chapter Flash Memory Module (FTFC), which tells you the utilization of flash, in detail, how to set the flash clock, how to erase sector or mass, how to program a sector, how to set the EEPROM mode for some chips, how to read a cell, how to set security mode to avoid the flash contents is read via jtag illegally..., it is enough to manipulate flash.
Pls refer to the chapter Flash Memory Module (FTFC) to understand how to perform flash.
Hope it can help you.
