Hi Erich,
Thanks for your reply. Maybe we will use KM34Z for product design.
Another question: I get a meter reference design Kit from freescale, but I can't find the hardware design schematic.
On the PCB, is says "MKM33Z128CLH5_1PH EMETER_REV 3.0", the MCU is LQFP64.
I can find the "DRM142.pdf" and "DRM143.pdf", but the MCU in the schematic is LQFP100.
Would you please help me to find the schematic for this Kit?
Regards
Sam
