I'm using the USB transceiver CY7C68003. In the datasheet, we can see that there's some difference for the pin order between the two type of package for this device.
24-Pin QFN: counter-clockwise, DATA, DATA ... DATA; DP, DM.
20-Ball WLCSP: counter-clockwise, DATA, DATA ... DATA; DM, DP.
Who can tell me why there's such a difference pin order between the two type of package?
Does Cypress suggest that when using the 24-Pin QFN package, put it on the same side on the PCB with the MCU, and when using the 20-Ball WLCSP package, put it on the opposite side on the PCB with the MCU?
Any help will be appreciated!
Ohh, nobody be interested in it?
