66 / 85 page ![]() PowerPC 440SP Embedded Processor 66 AMCC Proprietary Revision 1.23 - Sept 26, 2006 Data Sheet Input Max Allowable Overshoot (3.3V LVTTL) VIMAO +3.9 V Input Max Allowable Undershoot (3.3V LVTTL) VIMAU -0.6 V Output Max Allowable Overshoot (3.3V LVTTL) VOMAO +3.9 V Output Max Allowable Undershoot (3.3V LVTTL) VOMAU3 -0.6 V Case Temperature TC -40 +100 °C6 Notes: 1. PCI-X drivers meet PCI-X specifications. 2. SVREF = SVDD/2 3. The analog voltages used for the on-chip PLLs can be derived from the logic voltage, but must be filtered before entering the PPC440SP. See “Absolute Maximum Ratings” on page 63. 4. Power supply sequencing: It is recommended that the 1.5V Vdd of the core reach its nominal value before applying power to the I/Os. Voltage applied to I/Os from an external source must not be allowed to exceed the 0Vdd ramp. A power down cycle must complete (0Vdd and Vdd are below 0.4V) before a new power up cycle is started. 5. LPDL is least positive down level; MPUL is most positive up level. 6. Case temperature, TC, is measured at top center of case surface with device soldered to circuit board. Table 10.
