Note:
1. Maximum power is characterized at VDD = 2.7V, OVDD = 3.6V, TC = 85°C, across the silicon process (worse case to best case),
while running an application designed to maximize power consumption. The specification at 200MHz corresponds to
CPU = 200 MHz, PLB = 100MHz, OPB = EBC = 50MHz. The 266MHz maximum power was measured with CPU = 266.6MHz,
PLB =133.3MHz, OPB = EBC = 66.6MHz.
2. AVDD should be derived from VDD using the following circuit:
L1 – 2.2µH SMT inductor (equivalent to MuRata
LQH3C2R2M34) or SMT chip ferrite bead (equivalent
to MuRata BLM31A700S)

Clock timing and switching characteristics are specified in accordance
with operating conditions shown in the table “Recommended DC
Operating Conditions.” AC specifications are characterized at
OVDD = 3V and TJ = +85°C with the 50pF test load shown in the
50pF
figure at right.
