The design is packaged in arobust enclosure that allows evaluation on an engine in a dynamometer and in vehicles.This ECU implements a range of sensors and actuators typical of a drive-by-wire port fuel injection engine control systemmeeting the EU Stage-V emissions level. It is intended to be representative rather than an exact feature set. One example ofpossible sensors and actuators is shown in the block diagram Figure [CROSS REFERENCE FIGURE 1].Some of the sensors would be expected on all such systems, such as the engine and air temperature sensors. Some would not,such as the fuel level input. Some of the actuators would be expected on all such systems, such as the four fuel injectors.Some would not, such as the fuel efficiency gauge. There are three sources of variation possible on this ECU design:1. Whilst some inputs are dedicated to particular functions, for example the knock sensor pins on the MCU, others aregeneral, such as most other ADC inputs, and thus might be used for different functions.2. Whilst some outputs are dedicated to particular functions, for example the ignition coil pins from the IGBTs andMC33810, others are general, such as the MC33800 low side drivers, and thus might be used for different functions.3. In a small number of cases alternative devices might be connected to the output pins: specifically, jumpers can be usedto configure whether the MC33932 or the MC33879 is connected to the external actuator. This allows the option ofdriving either low, high or totem pole 1A loads, or a 5A H-bridge.Features of the module include: 32-bit Power Architecture core Microcontroller with 1.5 MBytes of flash and 94 KBytes of SRAM.8-bit Microcontroller connected to be able to perform intelligent safety checkingTwo CAN interfaces, ISO 11898-2 and 11898-5 compliant, one wired for diagnostic capabilitiesOne LIN (LIN 2.0 and 1.3 compliant, and SAE J2602 compatible) or K-Line interfaceMPC563xM Engine Control Unit Reference Design, Rev. 0, Draft C, 16 August 20112PreliminaryGeneral Business InformationFreescale Semiconductor, Inc.

MPC563xM example engine reference design block diagram2.1 Enclosure overviewThe enclosure used in the design is a commercially available robust unit manufactured by Cinch in the USA and purchasablethrough distributors such as Newark. The intent is to enable the hardware to be evaluated in harsh environments such as anengine bay or dynamometer. The case is not rated for full automotive temperature range, nor has the board been evaluated forthis. Although a heat-sink bracket is used, the enclosure is designed for heat-sinking of leaded TO220 package devices and sothe thermal paths from the SMD SMOS (surface mount transistors) is not ideal. The enclosure is waterproof. It is also cliptogether. If it is desirable to open it up without the dedicated and somewhat costly tool available from Cinch, removal of the10 barbs on the long edges is recommended. This permits the case to be opened using a screwdriver to gently lever the twolarge barbs on the short edges. With the case seal removed this process can be repeated many times. Removing the small2.Two options are implemented for air control: full Electronic Throttle Control using an H-bridge driven DC motorcontrol or four 1A totem outputs for a bypass air stepper motor.MPC563xM Engine Control Unit Reference Design, Rev. 0, Draft C, 16 August 2011Freescale Semiconductor, Inc.PreliminaryGeneral Business Information3
MPC563xM overviewbarbs will at the same time adversely affect the sealing of the enclosure. The two loom side connectors are keyed and cannotbe installed incorrectly. Terminals for the loom side connector are available in two sizes to fit different wire gauges. Thesmaller size was used for the powertrain demonstration built around this ECU. Hole blanks are available for sealing the loomside header in positions where wires are not fitted.2.2 Software overviewThe demonstration software available does not, nor is it intended to meet Stage V emissions. It is intended to be nonproduction code that might be examined to provide an example idea as to how these devices can be controlled. Freescale hasno control over the exact engine or system configuration to which the ECU might be attached, nor do we run validationprograms on engines or cars. However, parts of the code might successfully be used within an application to achieve thedesired functions. It is the responsibility of all users to validate their own code.Due to the complexity of the task, a description of the code architecture and functionality will be released in a separateapplication note.2.3 Layout overviewThe PCB layout is available in Gerber and Altium formats. The Gerber files are an industry standard for multiple layerboards that requires the user to re-construct the PCB from multiple files. The order of the layers is important and must beadhered to. Free Gerber viewers are available such as Gerbtool [link]. The Altium format contains all layers pre-assembled. Itis more powerful and also more complex to drive, but provides better features such as Net identification and search. A freeviewer is available as a large download [link].With the connector on the left, the PCB is divided approximately into four sections as shown in Figure x.x[artwork p10]. Atthe top by the heat-sink are the high voltage and high current drivers. The ignition coils are particularly noisy, and emitbroadband noise up to the 10's MHz region as the energy stored in the coils is transferred to the spark plugs. Switching ofmultiple amps is required and produces hundreds of volts. These drivers are closely couple with the front connector via highcurrent tracks, and kept clear of sensitive inputs. The high current motor driver tracks are likewise kept toward the top regionof the board, with the somewhat lower current injectors and PWM outputs from the MC33800 and MC33879 further down.In the bottom right corner is the digital section. This includes the MPC5634M microcontroller, with closely coupled tracksfor the crystal oscillator and carefully applied capacitor decoupling. The high speed digital NEXUS interface is in this corneras well as the lower speed JTAG interface. Also associated with the digital side is the MC9S08 safety micro, and digital CANinterfaces.The bottom left corner contains the analog inputs. Some, such as the crank sensor interface, must be particularly sensitive asthe input signal might be only 150mVp-p. Analog inputs such as throttle and MAP are critical to engine control and shouldbe kept as quiet as possible.In-between the analog and high current drivers is the power supply. This forms some degree of barrier to some of the noise.General advice on laying out PCBs can be found on the Freescale website, such as presentation FTF11 ENT F0964 fromworkshops held at the Freescale Technology Forum events.3 MPC563xM overviewThe MPC563xM family of devices are highly integrated, 32-bit Power Architecture microcontrollers that are intendedprimarily for low-end 4-cylinder gasoline engines; however they can be used for many other types of applications. Thedevice contains many features designed for powertrain control. The MPC563xM Reference ECU makes use of these andshows the hardware connected in a representative way. Two of the features that are highlighted in this design are theenhanced Timing Processing Unit (eTPU) and the knock processing sub-system incorporated into the device.MPC563xM Engine Control Unit Reference Design, Rev. 0, Draft C, 16 August 20114PreliminaryGeneral Business InformationFreescale Semiconductor, Inc.

MPC563xM overviewMany of the PMC reference and output voltages can be monitored by the on chip Analog to Digital Converter (eQADC).These on-chip voltages can therefore be monitored by the application software. As well as monitoring power supplies on allpin banks, and ADC references, there is an internal temperature sensor and bandgap reference for application use. Some ofthese signals can only be converted by one of the on-chip ADCs. The available PMC signal channels are shown in thefollowing table.Table 6.

The voltage on this channel should be compared to the buffered Band Gap voltage to determine the actual low voltage trippoint.3.5 Internal Power SuppliesThe VDD Regulator Input (VDDREG) is the 5 volt input to the internal 3.3 volt regulator and 1.2 volt regulator controller. Ifthe internal regulators are not being used, VDDREG can be tied to VSS to disable their operation. However, this disablesinternal low voltage detect circuits. To keep the internal low-voltage detect circuits powered, VDDREG can be connected to5 volts, even when the internal regulator circuits are not used.MPC563xM Engine Control Unit Reference Design, Rev. 0, Draft C, 16 August 2011Freescale Semiconductor, Inc.PreliminaryGeneral Business Information9
MPC563xM overview3.5.1 3.3 Volt Power SupplyThe 3.3 volt internal regulator is completely contained within the device and only requires the input supply (VDDREG) and abypass capacitor on the 3.3 volt output (VRC33). The 3.3 volt supply is used for internal operation of the device, includingpowering parts of the flash module within the device.The 3.3 volt regulator is intended to power internal circuitry only and was not designed to power external pins of the device.However, there are times that this supply could be used power a small number of pins. {Note - this needs to be evaluatedfurther.}NOTEIn the 144 QFP package, the JTAG/Nexus pins output a 3.3 volt level, however, thesesignals are not powered by the 3.3 internal regulator. These pins are powered by the 5volt power supply and the output voltage is limited in the output drivers of the signals.On the MPC563xM ECU VRC33 is used for the reference on the debug connector for theJTAG/Nexus interface.3.5.2 1.2 Volt Power Supply Input and Regulator ControllerThe majority of the internal device circuitry is powered by the 1.2 volt VDD input. This includes all of the CPU core and themajority of the internal logic of the device. An internal regulator controller is implemented to provide a low cost powersupply option. By utilizing an external transistor, the power loss from reducing the 5 volt supply to 1.2 volts does not have tobe dissipated within the MCU package and can be handled externally.The 1.2V regulator controller provides a current signal (VRCCTL) that feeds the base of an external NPN transistor. Thiscontrols the current flow from the 5 volt supply (approximately 3-7V range permissible) connected to the transistor collectorand the transistor emitter provides the 1.2 volt supply. Inside the package, a sense signal is connected to the VDD internalsupply input. This signal is compared to an internal Band Gap reference that sets the regulator reference voltage. Dependingon the voltage on VDD, the current on the VRCCTL signal is raised or lowered to maintain the 1.2 volt level.3.5.2.1Power Management Controller 1.2V External CircuitryThe figure below shows the required external circuitry for the internal regulators of the device. Some of this circuitry may notbe required, but space should be saved for all of these components for the target system. Evaluation of the final board layoutand the external power supply may allow some of these components to be removed.Regulator stability is controlled by many factors, including the phase response of the regulator loop. The transistor responseand parasitic components due to PCB layout impact the phase response yet are external to the MCU. It can also be affectedby noise coupling from the supply feeding the regulator (5 volt supply). The loop also depends on the gain of the transistor,the impedance of the 5V power supply, and the transient response time of that supply. Slower transient response times willrequire additional bulk capacitance at the MCU to compensate for the response time of the power supply.A bypass capacitor should be added right at the collector of the external NPN pass transistor, which should be connected toVDDREG.A snubber circuit should be connected on the VRCCTL signal from MCU to the base of the external pass transistor. Thisresistor-capacitor arrangement adjusts the phase of the loop to compensate for excessive parasitic inductance and eliminateany oscillation. The snubber circuit also reduces any noise coupling from the source supply for the pass transistor. Thisprovide the most robust solution for any typical situationMPC563xM Engine Control Unit Reference Design, Rev. 0, Draft C, 16 August 201110PreliminaryGeneral Business InformationFreescale Semiconductor, Inc.

The source bypass capacitor and the VDDREG Bypass capacitor can be the same if there is no Resistance betweenVDDREG and the collector of the pass transistor.A series resistor (RS) can be used on the pass transistor collector to reduce the power dissipation required by the passtransistor. Depending on the transistor selected, the power dissipation to required to drop the VDDREG voltage (nominal 5volts) down to the VDD voltage (1.2V) may be more than the transistor package allows for the temperature encountered andheatsinking provided. If RS is used, both the transistor collector and VDDREG should be bypassed. If RS is not used, a singlebypass capacitor can be used for both. In this case, the capacitor should be close to the transistor collector, but should still beplaced close to VDDREG.An alternate method to reduce the power dissipation requirements of the pass transistor is to use a nominal 3.3V source (if asuitable external 3.3V supply is available in the target system) for the transistor collector. In this case, VDDREG should stillbe connected to the nominal 5 volt supply. Both supplies should be well bypassed.MPC563xM Engine Control Unit Reference Design, Rev. 0, Draft C, 16 August 2011Freescale Semiconductor, Inc.PreliminaryGeneral Business Information11
