64 / 85 page ![]() PowerPC 440SP Embedded Processor 64 AMCC Proprietary Revision 1.23 - Sept 26, 2006 Data Sheet Table 8. Package Thermal Specifications Thermal resistance values for the PPC440SP package in a convection environment are as follows: Parameter Symbol Airflow ft/min (m/sec) Unit Notes 0 (0) 100 (0.51) 200 (1.02) Junction-to-case thermal resistance θ JC 0.6 0.6 0.6 °C/W 1 Case-to-ambient thermal resistance (w/o heat sink) θ CA 15.5 13.1 11.9 °C/W 2 Range Minimum Maximum Junction-to-ball (typical) θ JB 6.5 6.5 °C/W 3 Notes: 1. Case temperature, TC, is measured at top center of case surface with device soldered to circuit board. For this part the junction temperature and the case temperature are essentially identical. 2. The case-to-ambient thermal resistance is measured in a JEDEC JESD51-6 standard environment; and may not accurately predict thermal performance in production equipment environments. The operational case temperature must be maintained. 3. 6.5 °C/W is the theoretical θ JB using an infinite heat sink. The larger number applies to the module mounted on a 1.8 mm thick, 2P card using 1oz. copper power planes, with an effective heat transfer area of 75mm2. Table 9. Recommended DC Operating Conditions (Sheet 1 of 3) Device operation beyond the conditions specified is not recommended. Extended operation beyond the recommended conditions can affect device reliability.
