4 56F803 technical data program and data flash memories can be independently bulk ? erased or erased in page sizes of 256 words. the boot flash memory can also be either bulk- or page - erased. a key application-specific feature of the 56F803 is the inclusion of a pulse width modulator (pwm) module. this module incorporates three complementary, individually programmable pwm signal outputs (the module is also capable of supporting three independent pwm functions, for a total of six pwm outputs) to enhance motor control functionality. complementary operation permits programmable dead time insertion, distortion correction via current sensing by software, and separate top and bottom output polarity control. the up-counter value is programmable to support a continuously variable pwm frequency. edge- and center-aligned synchronous pulse width control (0% to 100% modulation) is supported. the device is capable of controlling most motor types: acim (ac induction motors), both bdc and bldc (brush and brushless dc motors), srm and vrm (switched and variable reluctance motors), and stepper motors. the pwm incorporates fault protection and cycle-by-cycle current limiting with sufficient output drive capability to directly drive standard opto-isolators. a ? smoke-inhibit ? , write-once protection feature for key parameters and patented pwm waveform distortion correction circuit are also provided. the pwm is double-buffered and includes interrupt controls to permit integral reload rates to be programmable from 1 to 16. the pwm module provides a reference output to synchronize the adc. the 56F803 incorporates a separate quadrature decoder capable of capturing all four transitions on the two- phase inputs, permitting generation of a number proportional to actual position. speed computation capabilities accommodate both fast and slow moving shafts. the integrated watchdog timer in the quadrature decoder can be programmed with a time-out value to alarm when no shaft motion is detected. each input is filtered to ensure only true transitions are recorded. this controller also provides a full set of standard programmable peripherals that include a serial communications interface (sci), one serial peripheral interface (spi), and four quad timers. any of these interfaces can be used as general purpose input/outputs (gpio) if that function is not required. a controller area network interface (can version 2.0 a/b-compliant) and an internal interrupt controller are also included on the 56F803. 1.3 state of the art development environment  processor expert tm (pe) provides a rapid application design (rad) tool that combines easy-to- use component-based software application creation with an expert knowledge system.  the code warrior integrated development environment is a sophisticated tool for code navigation, compiling, and debugging. a complete set of evaluation modules (evms) and development system cards will support concurrent engineering. together, pe, code warrior and evms create a complete, scalable tools solution for easy, fast, and efficient development. f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .

general characteristics 56F803 technical data 15 part 3 specifications 3.1 general characteristics the 56F803 is fabricated in high-density cmos with 5-v tolerant ttl-compatible digital inputs. the term ? 5-v tolerant ? refers to the capability of an i/o pin, built 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 supplies. in such systems, a bus may carry both 3.3v and 5v-compatible i/o voltage levels (a standard 3.3v i/o is designed to receive 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 without being damaged. absolute maximum ratings given in table 19 are stress ratings only, and functional operation at the maximum is not guaranteed. stress beyond these ratings may affect device reliability or cause permanent damage to the device. the 56F803 dc/ac electrical specifications are preliminary and are from design simulations. these specifications may not be fully tested or guaranteed at this early stage of the product life cycle. finalized specifications will be published after complete characterization and device qualifications have been completed. 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. table 19. absolute maximum ratings characteristic symbol min max unit supply voltage v dd v ss ? 0.3 v ss + 4.0 v all other input voltages, excluding analog inputs v in v ss ? 0.3 v ss + 5.5v v analog inputs ana0-7 and vref v in v ssa ? 0.3 v dda + 0.3 v analog inputs extal and xtal v in v ssa ? 0.3 v ssa + 3.0 v current drain per pin excluding v dd , v ss , pwm outputs, tcs, v pp , v dda , v ssa i ? 10 ma f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .

thermal design considerations 56F803 technical data 43 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-ambient thermal resistance c/w p d = power dissipation in package historically, thermal resistance has been expressed as the sum of a junction-to-case thermal resistance and a case-to-ambient thermal resistance: equation 2: where: r ja = package junction-to-ambient 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 cannot be influenced by the user. the user controls the thermal environment to change the case-to-ambient thermal resistance, r ca . for example, the user can change the air flow around the device, add a heat sink, change the mounting arrangement on the printed circuit board (pcb), or otherwise change the thermal dissipation capability of the area surrounding the device on the pcb. this model is most useful for ceramic packages 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 ceramic packages, in situations where the heat flow is split between a path to the case and an alternate path through the pcb, analysis of the device thermal performance may need the additional modeling capability of a system level thermal simulation tool. the thermal performance of plastic packages is more dependent on the temperature 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 system level model may be appropriate. definitions: a complicating factor is the existence of three common definitions for determining the junction-to-case thermal resistance in plastic packages:  measure the thermal resistance from the junction to the 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.  measure the thermal resistance from the junction to where the leads are attached to the case. this definition is approximately equal to a junction to board thermal resistance. t j t a p d r ja () + = r ja r jc r ca + = f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .
44 56F803 technical data  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 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 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 thermocouple inserted at the interface between the case of the package and the interface material. a clearance slot or hole is normally required in the heat sink. minimizing the size of the clearance is important to minimize the change in thermal performance caused by removing part of the thermal interface to the heat sink. because of the experimental difficulties with this technique, many engineers measure the heat sink temperature and then back-calculate the case temperature using a separate measurement of the thermal resistance of the interface. from this case temperature, the junction temperature is determined from the junction-to-case thermal resistance. f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .
electrical design considerations 56F803 technical data 45 5.2 electrical design considerations use the following list of considerations to assure correct operation:  provide a low-impedance path from the board power supply to each v dd pin on the hybrid controller, and from the board ground to each v ss (gnd) 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 configuration is to place one bypass capacitor on each of the v dd /v ss pairs, including v dda /v ssa. ceramic and tantalum capacitors tend to provide better performance tolerances.  ensure that capacitor leads and associated printed circuit traces that connect to the chip v dd and v ss (gnd) 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 lengths should be minimal.  consider all device loads as well as parasitic capacitance due to pcb traces when calculating capacitance. this is especially critical in systems with higher capacitive loads that could create higher transient currents in the v dd and gnd 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 require 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 allow in-circuit flash programming. 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. f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .
