Hi, Mark
You can find all the information regarding the IDE and the programmer in the next link
KE04 |Kinetis KE04 48 MHz Robustness MCUs|Freescale
As you can see, you could use different IDE, such as CW, KDS, etc. For the programmer, the one compatible with the KE04Z is the CycloneMax for P&E, is also listed in the link above.
I've attached the Reference Manual, which describes all the features, architecture and programming model of the KE04Z.
Hope it helps!
Regards
Patricia
