Hi,

i would like to know, what is the recommended JTAG connector for uC - #MPC5746B/C#

The background is that, currently our two projects are using 14 pin JTAG connectors with this kind of uC. There is a new project though, which uses the same kind of uC (but with smaller package size because of the board size), therefore there is a question whether we can use 10pin JTAG connector or not to fit with the smaller HW.

Do you know if this is possible? or which is recommended?

Thanks.

Hi @YiGao 
I can see no problem here. Mandatory signals are TDI, TDO, TCK, TMS, RESET, VREF, GND.
JCOMP is not available on this device, EVTI is optional and it is usually not used on JTAG (only on Nexus connector for trace). You will just need some converter when programmer/debugger with standard 14-pin connector is used.
I found this 10-pin ECU14 connector - page 156:
