Hi freescale,

                   We are using FRDM-KL25z with FRDM-FXS-MULTI-B rev C, In FRDM-FXS-MULTI-B rev C schematic U4 placement you have used FXAS21000cq but in board you used another vendor ic, its top marking is LEON-LOT08-C3908-DJJZT. if you used freescale ic means its not reflecting the freescale code 263 in top please clarify to me

Hi Deepi,

It is indeed Freescale IC, LEON is an internal nickname for the FXAS21000CQ. It looks like some preproduction samples use such a top marking.

That said, the FXAS21000CQ is no longer manufactured and has been replaced by FXAS21002CQR1. Our AN4917 describes the hardware and software differences between these parts and provides information on transitioning from FXAS21000CQ to FXAS21002CQR1.


I hope it helps.


Regards,

Tomas
