Power Characteristics
Table 5 shows the estimated typical I/O power dissipation for MPC8349EA.
2
Typical power is based on a voltage of V
DD
= 1.2 V, a junction temperature of T
J
= 105
°
C, and a Dhrystone benchmark
application.
3
Thermal solutions may need to design to a value higher than typical power based on the end application, T
A
target, and I/O
power.
4
Maximum power is based on a voltage of V
DD
= 1.2 V, worst case process, a junction temperature of T
J
= 105
°
C, and an
artificial smoke test.
5
Typical power is based on a voltage of V
DD
= 1.3 V, a junction temperature of T
J
= 105
°
C, and a Dhrystone benchmark
application.
6
Maximum power is based on a voltage of V
DD
= 1.3 V, worst case process, a junction temperature of T
