4 / 12 page MPC7448 Hardware Specifications Addendum for the MC7448xxnnnnNx Series, Rev. 6 4 Freescale Semiconductor General Parameters 4 General Parameters Core power supply 1.15 V (1400 MHz devices) 1.1 V (1267, 1250 MHz devices) 1.05 V (1267 MHz revision level D devices only, See Table 17.) 1.0 V (1000, 867, 800, 667, 600 MHz devices) Note: See Section 5.1, “DC Electrical Characteristics,” for information regarding VDD specifications for 1400 MHz devices. 5.1 DC Electrical Characteristics Table 4 provides the recommended operating conditions for the MPC7448 part numbers described here. NOTE Table 4 describes the nominal operating conditions of the device. For information on the operation of the device at supported derated core voltage conditions, see Section 5.3, “Voltage and Frequency Derating.” Table 4. Recommended Operating Conditions 1 Characteristic Symbol Recommended Value Unit Notes 600 MHz, 667 MHz, 800 MHz, 867 MHz, 1000 MHz 1250 MHz, 1267 MHz3 Revision Level C for 1267 only 1267 MHz3 Revision Level D only 1400 MHz 3, 4 Core supply voltage VDD 1.0 V ± 50 mV 1.1 V ± 50 mV 1.05 V ± 50 mV 1.15 V ± 50 mV V PLL supply voltage AVDD 1.0 V ± 50 mV 1.1 V ± 50 mV 1.05 V ± 50 mV 1.15 V ± 50 mV V 2 Notes: 1. These are the recommended and tested operating conditions. Some speed grades in addition support voltage derating; see Section 5.3, “Voltage and Frequency Derating.” Proper device operation outside of these conditions and those specified in Section 5.3, “Voltage and Frequency Derating,” is not guaranteed. 2. This voltage is the input to the filter discussed in Section 9.2.2, “PLL Power Supply Filtering,” in the hardware specifications and not necessarily the voltage at the AVDD pin, which may be reduced from VDD by the filter. 3. VDD and AVDD may be reduced in order to reduce power consumption if further maximum core frequency constraints are observed. See Section 5.3, “Voltage and Frequency Derating,” for specific information. 4. Effective for 1400 MHz devices with date code of 0613 and later; this includes all devices with the ‘PPC’ product code. VDD and AVDD were specified at 1.1V ± 50 mV for 1400 MHz devices with date code 0612 and prior. See Section 11, “Part Numbering and Marking,” for more information. |
