Typical Powering Schematics
Adequate input supply decoupling is mandatory for VDDIN in order to improve startup stability
and reduce source voltage drop. The input decoupling capacitor should be placed close to the
chip. For example, two capacitors can be used in parallel: 100 nF NPO and 4.7 µF X7R.
The AT91SAM7XC512/256/128 supports a 3.3V single supply mode. The internal regulator
input connected to the 3.3V source and its output feeds VDDCORE and the VDDPLL.
