299 / 306 page  7 Mechanical Data 7.1 Thermal Data for ZWT TMS320DM6437 Digital Media Processor www.ti.com SPRS345D – NOVEMBER 2006 – REVISED JUNE 2008 The following table(s) show the thermal resistance characteristics for the PBGA–ZWT and ZDU mechanical package(s). For more details, see the Thermal Considerations for TMS320DM64xx, TMS320DM64x, and TMS320C6000 Devices Application Report (literature number SPRAAL9). Table 7-1. Thermal Resistance Characteristics (PBGA Package) [ZWT] NO. °C/W(1) AIR FLOW (m/s)(2) 1 R ΘJC Junction-to-case 5.4 N/A 2 R ΘJB Junction-to-board 16.0 N/A 3 26.6 0.00 4 R ΘJA Junction-to-free air 21.9 1.0 5 20.4 2.00 7 0.0 0.00 8 PsiJT Junction-to-package top 0.1 1.0 9 0.2 2.00 11 15.9 0.00 12 PsiJB Junction-to-board 15.8 1.0 13 15.3 2.00 (1) The junction-to-case measurement was conducted in a JEDEC defined 1S0P system. Other measurements were conducted in a JEDEC defined 1S2P system and will change based on environment as well as application. For more information, see these three EIA/JEDEC standards: • EIA/JESD51-2, Integrated Circuits Thermal Test Method Environment Conditions - Natural Convection (Still Air) • EIA/JESD51-3, Low Effective Thermal Conductivity Test Board for Leaded Surface Mount Packages • JESD51-7, High Effective Thermal Conductivity Test Board for Leaded Surface Mount Packages .
