Hi.
I have been looking over some of ST's EVAL board, and the one thing I notice is that all of the ones I've looked at ie STM3210x_EVAL,STM32100x_EVAL, and the Nucleo evals, all use a quarts xtal in a through hole can design (some don't populate the board, but its a can footprint on the PCB). I have always used a surface mounted TXD quartz crystal of about a 12pF load on almost everything I've put together using a micro, but I've never done this for a ST micro.

Is there a reason for this? Isn't it cheaper to use a surface mount footprint design? or is there an electrical reason to use a can type?

Thanks.
