Notes on Bypass Capacitors:
•
Caps for pins 7, 8 and 12, 13 MUST have trace lengths LESS than
5 mm.
•
The 0.1
µF
caps must be ceramic.
•
Caps should have less than 5 nH of self inductance
•
Caps should have less than 0.2
Ω
ESR
Surface mount parts are recommended.
SDIO and SCLK pins should be grounded if not used.
