MCF8316A: Pinout for IC vs EVM

Part Number: MCF8316A

I'm seeing some misalignment between the datasheet and evaluation board. Specifically with pins #36, #37, #38 on MCF8316A.

This means that pins #38 has SOX functionality, pins #36, #37 should be not connected. However in the EVM user guide, that SOX pin is placed on pin #36  (and not pin #38, as appear in the datasheet), while pins #38 and pins #37 are connected to 32 kHz crystal. In the datasheet pin #37 is a NC (#38 in the datasheet - is SOX).

Do I need to follow the DS or the EVM? If it should be datasheet, to which pins should I connect (optional) 32 kHz crystal ?  

  • Hi TJ,

    MCF8316A datasheet has the most updated and accurate information. Please follow the datasheet and ignore the schematic symbol of the device. Pin 36 and 37 are NC. Pin 38 has SOX functionality. An external clock source can be connected to pin 33.

    Regards,
