The AT91RM3400 has four types of power supply pins:
•
•
•
•
Ground pins are common for all power supplies except the VDDPLL and VDDOSC, for which
the GNDPLL and the GNDOSC pins are provided, respectively.
Powering VDDIO with a voltage lower than 3V prevents any use of the USB Device Port.
The AT91RM3400 is available in a 100-lead LQFP package.
VDDCORE pins power the chip core and must be between 1.65V and 1.95V, 1.8V
nominal.
VDDIO pins power the I/O lines and must be between 1.65V and 3.6V, 1.8V, 3V or 3.3V
nominal.
VDDPLL pin powers the PLL cells and must be between 1.65V and 1.95V, 1.8V nominal.
VDDOSC pin powers both oscillators and must be between 1.65V and 1.95V, 1.8V
nominal.
