They power the voltage regulator, the I/O lines, the Flash and the USB transceivers; voltage ranges from 3.0V to 3.6V , 3.3V nominal.•VDD1V8 pins. They are the outputs of the 1.8V voltage regulator and they power the logic of the device.•VDDPLL pin. It powers the PLL; voltage ranges from 1.65V to 1.95V , 1.8V typical. They can be connected to the VDD1V8 pin with decoupling capacitor.•VDDBU pin. It powers the Slow Clock oscillator and the Real Time Clock, as well as a part of the System Controller; ranges from 3.0V and 3.6V , 3.3V nominal.•VDDANA pin. It powers the ADC; ranges from 3.0V and 3.6V , 3.3V nominal.No separate ground pins are provided for the different power supplies. Only GND pins are pro-vided and should be connected as shortly as possible to the system ground plane.5.2Voltage RegulatorThe AT91SAM7A3 embeds a voltage regulator that consumes less than 120 µA static current and draws up to 130 mA of output current.Adequate output supply decoupling is mandatory for VDD1V8 (pin 99)to reduce ripple and avoid oscillations. The best way to achieve this is to use two capacitors in parallel: one external 470 pF (or 1 nF) NPO capacitor must be connected between VDD1V8 and GND as close to the chip as possible. One external 3.3 µF (or 4.7 µF) X7R capacitor must be connected between VDD1V8and GND.All other VDD1V8 pins must be externally connected and have a proper decoupling capacitor (at least 100 nF).Adequate input supply decoupling is mandatory for VDD3V3 (pin 100) in order to improve star-tup 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.All other VDD3V3 pins must be externally connected and have a proper decoupling capacitor (at least 100 nF).分销商库存信息: ATMELAT91SAM7A3-AU。
