mpc8272 powerquicc ii? family hardware specifications, rev. 1.1 12 freescale semiconductor thermal characteristics 4.2 estimation with junction-to-case thermal resistance historically, the thermal resistance has frequently been expressed as the sum of a junction-to-case thermal resistance and a case-to-ambient thermal resistance: r ja = r jc + r ca where: r ja = junction-to-ambient thermal resistance (oc/w) r jc = junction-to-case thermal resistance (oc/w) r ca = case-to-ambient thermal resistance (oc/w) r jc is device related and cannot be influenced by the user. the user adjusts the thermal environment to affect the case-to-ambient thermal resistance, r ca . for instance, the user can change the air flow around the device, add a heat sink, change the mounting arrangement on the printed circuit board, or change the thermal dissipation on the printed circuit board surrounding the device. this thermal model is most useful for ceramic packages with heat sinks where some 90% of the heat flows through the case and the heat sink to the ambient environment. for most packages, a better model is required. 4.3 estimation with junction-to-board thermal resistance a simple package thermal model which has demonstrated reasonable accuracy (about 20%) is a two-resistor model consisting of a junction-to-board and a junction-to-case thermal resistance. the junction-to-case thermal resistance covers the situation where a heat sink is used or where a substantial amount of heat is dissipated from the top of the package. the junction-to-board thermal resistance describes the thermal performance when most of the heat is conducted to the printed circuit board. it has been observed that the thermal performance of most plastic packages, especially pbga packages, is strongly dependent on the board temperature. if the board temperature is known, an estimate of the junction temperature in the environment can be made using the following equation: t j = t b + (r jb p d ) where: r jb = junction-to-board thermal resistance (oc/w) t b = board temperature (oc) p d = power dissipation in package if the board temperature is known and the heat loss from the package case to the air can be ignored, acceptable predictions of junction temperature can be made. for this method to work, the board and board mounting must be similar to the test board used to determine the junction-to-board thermal resistance, namely a 2s2p (board with a power and a ground plane) and by attaching the thermal balls to the ground plane. 4.4 estimation using simulation when the board temperature is not known, a thermal simulation of the application is needed. the simple two-resistor model can be used with the thermal simulation of the application, or a more accurate and complex model of the package can be used in the thermal simulation.
mpc8272 powerquicc ii? family hardware specifications, rev. 1.1 freescale semiconductor 13 thermal characteristics 4.5 experimental determination to determine the junction temperature of the device in the application after prototypes are available, the thermal characterization parameter ( jt ) can be used to determine the junction temperature with a measurement of the temperature at the top center of the package case using the following equation: t j = t t + ( jt p d ) where: jt = thermal characterization parameter t t = thermocouple temperature on top of package p d = power dissipation in package the thermal characterization parameter is measured per jedec jesd51-2 specification using a 40 gauge type t thermocouple epoxied to the top center of the package case. the thermocouple should be positioned so that the thermocouple junction rests on the package. a small amount of epoxy is placed over the thermocouple junction and over 1 mm of wire extending from the junction. the thermocouple wire is placed flat against the case to avoid measurement errors caused by cooling effects of the thermocouple wire. 4.6 layout practices each vdd and vddh pin should be provided with a low-impedance path to the board?s power supplies. each ground pin should likewise be provided with a low-impedance path to ground. the power supply pins drive distinct groups of logic on chip. the vdd and vddh power supplies should be bypassed to ground using by-pass capacitors located as close as possible to the four sides of the package. for filtering high frequency noise, a capacitor of 0.1uf on each vdd and vddh pin is recommended. further, for medium frequency noise, a total of 2 capacitors of 47uf for vdd and 2 capacitors of 47uf for vddh are also recommnded. the capacitor leads and associated printed circuit traces connecting to chip vdd, vddh and ground should be kept to less than half an inch per capacitor lead. boards should employ separate inner layers for power and gnd planes. all output pins on the mpc8272 have fast rise and fall times. printed circuit (pc) trace interconnection length should be minimized to minimize overdamped conditions and reflections caused by these fast output switching times. this recommendation particularly applies to the address and data buses. maximum pc trace lengths of six inches are recommended. capacitance calculations should consider all device loads as well as parasitic capacitances due to the pc traces. attention to proper pcb layout and bypassing becomes especially critical in systems with higher capacitive loads because these loads create higher transient currents in the vdd and gnd circuits. pull up all unused inputs or signals that will be inputs during reset. special care should be taken to minimize the noise levels on the pll supply pins. 4.7 references semiconductor equipment and materials international (415) 964-5111 805 east middlefield rd. mountain view, ca 94043 mil-spec and eia/jesd (jedec) specifications 800-854-7179 or (available from global engineering documents) 303-397-7956 jedec specifications http://www.jedec.org 1. c.e. triplett and b. joiner, ?an experimental characterization of a 272 pbga within an automotive engine controller module,? proceedings of semitherm, san diego, 1998, pp. 47 ? 54.
