9 / 104 page MPC8540 Integrated Processor Hardware Specifications, Rev. 4 Freescale Semiconductor 9 Electrical Characteristics 2.1.2 Power Sequencing The MPC8540 requires its power rails to be applied in a specific sequence in order to ensure proper device operation. These requirements are as follows for power up: 1. VDD, AVDD 2. GVDD, LVDD, OVDD (I/O supplies) Items on the same line have no ordering requirement with respect to one another. Items on separate lines must be ordered sequentially such that voltage rails on a previous step must reach 90 percent of their value before the voltage rails on the current step reach 10 percent of theirs. NOTE If the items on line 2 must precede items on line 1, please ensure that the delay will not exceed 500 ms and the power sequence is not done greater than once per day in production environment. NOTE From a system standpoint, if the I/O power supplies ramp prior to the VDD core supply, the I/Os on the MPC8540 may drive a logic one or zero during power-up. 2.1.3 Recommended Operating Conditions Table 2 provides the recommended operating conditions for the MPC8540. Note that the values in Table 2 are the recommended and tested operating conditions. Proper device operation outside of these conditions is not guaranteed. Table 2. Recommended Operating Conditions Characteristic Symbol Recommended Value Unit Core supply voltage For devices rated at 667 and 833 MHz For devices rated at 1 GHz VDD 1.2 V ± 60 mV 1.3 V ± 50 mV V PLL supply voltage For devices rated at 667 and 833 MHz For devices rated at 1 GHz AVDD 1.2 V ± 60 mV 1.3 V ± 50 mV V DDR DRAM I/O voltage GVDD 2.5 V ± 125 mV V Three-speed Ethernet I/O voltage LVDD 3.3 V ± 165 mV 2.5 V ± 125 mV V PCI/PCI-X, local bus, RapidIO, 10/100 Ethernet, MII management, DUART, system control and power management, I2C, and JTAG I/O voltage OVDD 3.3 V ± 165 mV V |
