24 / 77 page ![]() MPC5602D Microcontroller Data Sheet, Rev. 3.1 Preliminary—Subject to Change Without Notice Electrical characteristics Freescale Semiconductor 24 4.6 Thermal characteristics 4.6.1 Package thermal characteristics Table 10. LQFP thermal characteristics1 1 Thermal characteristics are targets based on simulation that are subject to change per device characterization. Symbol C Parameter Conditions2 2 V DD = 3.3 V ± 10% / 5.0 V ± 10%, TA = –40 to 125 °C Pin count Value3 3 All values need to be confirmed during device validation. Unit RJA CC D Thermal resistance, junction-to-ambient natural convection4 4 Junction-to-ambient thermal resistance determined per JEDEC JESD51-3 and JESD51-6. Thermal test board meets JEDEC specification for this package. When Greek letters are not available, the symbols are typed as RthJA and RthJMA. Single-layer board —1s 64 72.1 °C/W 100 65.2 Four-layer board — 2s2p 64 57.3 100 51.8 RJB CC D Thermal resistance, junction-to-board5 5 Junction-to-board thermal resistance determined per JEDEC JESD51-8. Thermal test board meets JEDEC specification for the specified package. When Greek letters are not available, the symbols are typed as RthJB. Single-layer board — 1s 64 45.6 °C/W 100 42.6 Four-layer board — 2s2p 64 44.1 100 41.3 RJC CC D Thermal resistance, junction-to-case6 6 Junction-to-case at the top of the package determined using MIL-STD 883 Method 1012.1. The cold plate temperature is used for the case temperature. Reported value includes the thermal resistance of the interface layer. When Greek letters are not available, the symbols are typed as RthJC. Single-layer board — 1s 64 26.5 °C/W 100 23.9 Four-layer board — 2s2p 64 26.2 100 23.7 JB CC D Junction-to-board thermal characterization parameter, natural convection Single-layer board — 1s 64 41 °C/W 100 41.6 Four-layer board — 2s2p 64 43 100 43.4 JC CC D Junction-to-case thermal characterization parameter, natural convection Single-layer board — 1s 64 11.5 °C/W 100 10.4 Four-layer board — 2s2p 64 11.1 100 10.2 |
