10 / 144 page MPC8548E PowerQUICC™ III Integrated Processor Hardware Specifications, Rev. 6 10 Freescale Semiconductor Electrical Characteristics 2 Electrical Characteristics This section provides the AC and DC electrical specifications and thermal characteristics for the MPC8548E. This device is currently targeted to these specifications. Some of these specifications are independent of the I/O cell, but are included for a more complete reference. These are not purely I/O buffer design specifications. 2.1 Overall DC Electrical Characteristics This section covers the ratings, conditions, and other characteristics. 2.1.1 Absolute Maximum Ratings Table 1 provides the absolute maximum ratings. Table 1. Absolute Maximum Ratings 1 Characteristic Symbol Max Value Unit Notes Core supply voltage VDD –0.3 to 1.21 V — PLL supply voltage AVDD –0.3 to 1.21 V — Core power supply for SerDes transceivers SVDD –0.3 to 1.21 V — Pad power supply for SerDes transceivers XVDD –0.3 to 1.21 V — DDR and DDR2 DRAM I/O voltage GVDD –0.3 to 2.75 –0.3 to 1.98 V— Three-speed Ethernet I/O voltage LVDD (for eTSEC1 and eTSEC2) –0.3 to 3.63 –0.3 to 2.75 V3 TVDD (for eTSEC3 and eTSEC4) –0.3 to 3.63 –0.3 to 2.75 3 PCI/PCI-X, DUART, system control and power management, I2C, Ethernet MII management, and JTAG I/O voltage OVDD –0.3 to 3.63 V — Local bus I/O voltage BVDD –0.3 to 3.63 –0.3 to 2.75 V— Input voltage DDR/DDR2 DRAM signals MVIN –0.3 to (GVDD + 0.3) V 4 DDR/DDR2 DRAM reference MVREF –0.3 to (GVDD/2 + 0.3) V— Three-speed Ethernet I/O signals LVIN TVIN –0.3 to (LVDD + 0.3) –0.3 to (TVDD + 0.3) V4 Local bus signals BVIN –0.3 to (BVDD + 0.3) — — DUART, SYSCLK, system control and power management, I2C, Ethernet MII management, and JTAG signals OVIN –0.3 to (OVDD + 0.3) V 4 PCI/PCI-X OVIN –0.3 to (OVDD + 0.3) V 4 |
