10 / 79 page  MPC8343EA PowerQUICC II Pro Integrated Host Processor Hardware Specifications, Rev. 10 10 Freescale Semiconductor Power Characteristics 3 Power Characteristics The estimated typical power dissipation for the MPC8343EA device is shown in Table 4. l Table 5 shows the estimated typical I/O power dissipation for MPC8343EA. Table 4. MPC8343EA Power Dissipation1 1 The values do not include I/O supply power (OV DD, LVDD, GVDD) or AVDD. For I/O power values, see Table 5. Core Frequency (MHz) CSB Frequency (MHz) Typical at TJ = 65 Typical2 ,3 2 Typical power is based on a voltage of V DD = 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, T A target, and I/O power. Maximum4 4 Maximum power is based on a voltage of V DD = 1.2 V, worst case process, a junction temperature of TJ = 105°C, and an artificial smoke test.
