Outline and pin positions checked against the manufacturer datasheet (C669482 19-C47 Rev.5 p7). Corner numbers on the top view: 1 top-right, 2 bottom-right, 3 bottom- left, 4 top-left (clockwise); the bottom view is turned over so it reads 3, 2 / 4, 1. Pads 0.7 x 0.7 mm with a 0.4 mm gap are marked 'suggested pad dimension, for reference only'. No pin-1 mark is drawn. What this means.
