56F807 technical data technical data, rev. 15 20 freescale semiconductor 2.14 jtag/once part 3 specifications 3.1 general characteristics the 56F807 is fabricated in high-de nsity cmos with 5v-tolerant ttl-c ompatible digital inputs. the term ?5v-tolerant? refers to the capabi lity of an i/o pin, bui lt on a 3.3v compatible process technology, to withstand a voltage up to 5.5v without damaging the device. many systems have a mixture of devices designed for 3.3v and 5v power suppl ies. in such systems, a bus ma y carry both 3.3v and 5v-compatible i/o voltage levels (a standard 3.3v i/o is designed to rece ive a maximum voltage of 3.3v 10% during normal operation without causing damage ). this 5v-tolerant capability therefore offers the power savings of 3.3v i/o levels while being able to receive 5v levels wi thout being damaged. absolute maximum ratings given in table 3-1 are stress ratings only, and functional operation at the maximum is not guaranteed. stress beyond these ratings may affect device reliability or cause permanent table 2-19 jtag/on-chip em ulation (once) signals no. of pins signal name signal type state during reset signal description 1 tck input (schmitt) input, pulled low internally test clock input ?this input pin provides a gated clock to synchronize the test logic and shift serial data to the jtag/once port. the pin is connected internally to a pull-down resistor. 1 tms input (schmitt) input, pulled high internally test mode select input ?this input pin is used to sequence the jtag tap controller?s state machine. it is sampled on the rising edge of tck and has an on-chip pull-up resistor. note: always tie the tms pin to v dd through a 2.2k resistor. 1 tdi input (schmitt) input, pulled high internally test data input ?this input pin provides a serial input data stream to the jtag/once port. it is sampled on the rising edge of tck and has an on-chip pull-up resistor. 1 tdo output tri-stated test data output ?this tri-statable output pi n provides a serial output data stream from the jtag/once port. it is driven in the shift-ir and shift-dr controller states, and changes on the falling edge of tck. 1 trst input (schmitt) input, pulled high internally test reset ?as an input, a low signal on this pin provides a reset signal to the jtag tap controller. to ensu re complete hard ware reset, trst should be asserted at power-up and whenever reset is asserted. the only exception occurs in a debugging environment when a hardware device reset is required and it is nec essary not to reset the once/jtag module. in this case, assert reset , but do not assert trst . note: for normal operation, connect trst directly to v ss . if the design is to be used in a debugging environment, trst may be tied to v ss through a 1k resistor. 1 de output output debug event ?de provides a low pulse on recognized debug events.

thermal design considerations 56F807 technical data technical data, rev. 15 freescale semiconductor 55 part 5 design considerations 5.1 thermal design considerations an estimation of the chip junction temperature, t j , in c can be obtained from the equation: equation 1: where: t a = ambient temperature c r ja = package junction-to-ambie nt thermal resistance c/w p d = power dissipation in package historically, thermal resistance has been expressed as the sum of a j unction-to-case thermal resistance and a case-to-ambient thermal resistance: equation 2: where: r ja = package junction-to-ambie nt thermal resistance c/w r jc = package junction-to-case thermal resistance c/w r ca = package case-to-ambient thermal resistance c/w r jc is device-related and ca nnot be influenced by the user. the user controls the thermal environment to change the case-to-ambien t thermal resistance, r ca . for example, the user ca n change the air flow around the device, add a heat sink, change the mounting ar rangement on the printed circuit board (pcb), or otherwise change the thermal diss ipation capability of the area su rrounding the device on the pcb. this model is most useful for ceramic pa ckages with heat sinks; some 90% of the heat flow is dissipated through the case to the heat sink and out to the ambient environment. for cera mic packages, in situations where the heat flow is split between a path to the case a nd an alternate path through the pcb, analysis of the device thermal performance may need the additional modeli ng capability of a sy stem level thermal simulation tool. the thermal performance of plastic packages is more dependent on the temperat ure of the pcb to which the package is mounted. again, if the estimations obtained from r ja do not satisfactorily answer whether the thermal performance is adequate, a sy stem level model may be appropriate. definitions: a complicating factor is the existe nce of three common definitions fo r determining the junction-to-case thermal resistance in plastic packages: ? measure the thermal resistance from the junction to th e outside surface of the package (case) closest to the chip mounting area when that surface has a proper heat sink. this is done to minimize temperature variation across the surface. t j t a p d r ja () + = r ja r jc r ca + =
56F807 technical data technical data, rev. 15 56 freescale semiconductor ? measure the thermal resistance from the junction to where the leads are attached to the case. this definition is approximately equal to a junc tion to board thermal resistance. ? use the value obtained by the equation (t j ? t t )/p d where t t is the temperature of the package case determined by a thermocouple. the thermal characterization parameter is measured per jesd51-2 specification using a 40-gauge type t thermocouple epoxied to the top ce nter of the package case. the th ermocouple should be positioned so that the thermocouple junction re sts on the package. a small amount of epoxy is placed over the thermocouple junction and over about 1mm of wire extending from the junction. the thermocouple wire is placed flat against the package case to avoid measurement errors caused by cooling effects of the thermocouple wire. when heat sink is used, the junction temperature is determined from a ther mocouple inserted at the interface between the case of the p ackage and the interface material. a clearance slot or hole is normally required in the heat sink. minimizing the size of the clearan ce is important to mi nimize the change in thermal performance caused by removing part of the thermal interface to the heat sink. because of the experimental difficulties with th is technique, many engine ers measure the heat si nk temperature and then back-calculate the case temperatur e using a separate measurement of the thermal resistance of the interface. from this case temperat ure, the junction temperature is de termined from th e junction-to-case thermal resistance. 5.2 electrical design considerations use the following list of considerat ions to assure correct operation: ? provide a low-impedance path from the board power supply to each v dd pin on the controller, and from the board ground to each v ss pin. ? the minimum bypass requirement is to place 0.1 f capacitors positioned as close as possible to the package supply pins. the recommended bypass configura tion is to place one bypass capacitor on each of the v dd /v ss pairs, including v dda /v ssa. ceramic and tantalum capacito rs tend to provide better performance tolerances. caution this device contains protective circuitry to guard against damage due to high static voltage or electrical fields. however, normal precautions are advised to avoid application of any voltages higher than maximum rated voltages to this high-impedance circuit. reliability of operation is enhanced if unused inputs are tied to an appropriate voltage level.
electrical design considerations 56F807 technical data technical data, rev. 15 freescale semiconductor 57 ? ensure that capacitor leads and associated prin ted circuit traces that connect to the chip v dd and v ss pins are less than 0.5 inch per capacitor lead. ? bypass the v dd and v ss layers of the pcb with approximately 100 f, preferably with a high-grade capacitor such as a tantalum capacitor. ? because the controller?s output signals have fast rise and fall times, pcb trace le ngths should be minimal. ? consider all device loads as well as parasitic capacitance due to pcb traces when calculating capacitance. this is especially critical in system s with higher capacitive loads that co uld create higher transient currents in the v dd and v ss circuits. ? take special care to minimize noise levels on the vref, v dda and v ssa pins. ? designs that utilize the trst pin for jtag port or once module functionality (such as development or debugging systems) should allow a means to assert trst whenever reset is asserted, as well as a means to assert trst independently of reset . trst must be asserted at power up for proper operation. designs that do not requir e debugging functionality, such as consumer products, trst should be tied low. ? because the flash memory is programmed through the jtag/once port, designers should provide an interface to this port to allo w in-circuit flash programming.
