That's never been released info. We can guess, but we don't know for sure. It's in the ballpark of 5.25 x 2.95, but be aware that the HVX200's chip is slightly smaller than the HVX200A/HPX170/HMC150 chip, so ... the best you're going to get are guesses, unless you can find a repair facility that's got a broken one torn open so you can actually measure.
