where N is the number of output pins switching in a group M, C is the capacitance per pin, VDD_IO is the

IO voltage swing, f is the switching frequency and PIOint is the power consumed by the unloaded IO stage.

The total power consumption of the MPC5200 processor must not exceed the value, which would cause

the maximum junction temperature to be exceeded.

Operational 727.5 1080 mW

NOTES:

Typical core power is measured at VDD_CORE = 1.5 V, Tj = 25 C

Operational power is measured while running an entirely cache-resident program with floating-point

multiplication instructions in parallel with a continuous PCI transaction via BestComm.

D5.1

Doze — 600 mW

Doze power is measured with the G2_LE core in Doze mode, the system oscillator, System PLL and Core PLL

are active, all other system modules are inactive

D5.2

Nap — 225 mW

Nap power is measured with the G2_LE core in Nap mode, the stem oscillator, System PLL and Core PLL are

active, all other system modules are inactive

D5.3

Sleep — 225 mW

Sleep power is measured with the G2_LE core in Sleep mode, the stem oscillator, System PLL and Core PLL

are active, all other system modules are inactive

D5.4

Deep-Sleep 52.5 52.5 mW

Deep-Sleep power is measured with the G2_LE core in Sleep mode, the stem oscillator, System PLL, Core PLL

and all other system modules are inactive

Unloaded I/O Power Supplies (VDD_IO, VDD_MEM_IO

)

IO power figures given in the table represent the worst case scenario. For the mem_io rail connected to 2.5V the

IO power is expected to be lower and bounded by the worst case with VDD_MEM_IO connected to 3.3V.
