Freescale Semiconductor 

Power Characteristics

2 Typical power is based on a voltage of VDD = 1.2 V, a junction temperature of TJ = 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, TA target, and I/O

power.

4 Maximum power is based on a voltage of VDD = 1.2 V, worst case process, a junction temperature of TJ = 105°C, and an

artificial smoke test.

5 Typical power is based on a voltage of VDD = 1.3 V, a junction temperature of TJ = 105°C, and a Dhrystone benchmark

application.

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

artificial smoke test.

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