As long as you know the layout and have access to pads somewhere on the circuit board it's always the best solution because you'll avoid all the mess.
Plus 99% it doesn't have to be replaced, you're just doing it for fun or to perform a firmware corruption recover / downgrade or patch
Don't worry about the clock frequency, just wire connect to an empty SD card holder and insert it to a computer SD card reader/writer or a SD to USB adapter reader/writer. It contents will be ready to full access. If you need a 'low level' access use WinHex or any other alike tool.
