Power Characteristics

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.

Thermal solutions may need to design to a value higher than typical power based on the end application, T_Atarget, and I/O

power.

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.

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.

Maximum power is based on a voltage of V_DD= 1.3 V, worst case process, a junction temperature of T_J= 105°C, and an

artificial smoke test.

Table 5 shows the estimated typical I/O power dissipation for MPC8349EA.
