MPC8358E PowerQUICC™ II Pro Processor Revision 2.1 PBGA Silicon Hardware Specifications, Rev. 1

Freescale Semiconductor

Power Characteristics

fully ramp up. In the case where the core voltage is applied first, the core voltage supply must rise to 90%

of its nominal value before the I/O supplies reach 0.7 V, see Figure 4.

Figure 4. Power Sequencing Example

I/O voltage supplies (GVDD, LVDD, and OVDD) do not have any ordering requirements with respect to one

another.

2.2.2

Power-Down Sequencing

The MPC8358E does not require the core supply voltage and I/O supply voltages to be powered-down in

any particular order.

Power Characteristics

The estimated typical power dissipation values are shown in Table 4.

Notes:

1. The values do not include I/O supply power (OVDD, LVDD, GVDD) or AVDD. For I/O power values, see Table 5.

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 will likely need to design to a value higher than typical power on the end application, TA target, and I/O

power.

4. Maximum power is based on a voltage of VDD = 1.2 V, WC process, a junction TJ = 105°C, and an artificial smoke test.
