1.2 56F807 Description
The 56F807 is a member of the 56800 core-based family of processors. It combines, on a single chip, the
processing power of a DSP and the functionality of a microcontroller with a flexible set of peripherals to
create an extremely cost-effective solution. Because of its low cost, configuration flexibility, and compact
program code, the 56F807 is well-suited for many applications. The 56F807 includes many peripherals
that are especially useful for applications such as motion control, smart appliances, steppers, encoders,
tachometers, limit switches, power supply and control, automotive control, engine management, noise
suppression, remote utility metering, industrial control for power, lighting, and automation.
The 56800 core is based on a Harvard-style architecture consisting of three execution units operating in
parallel, allowing as many as six operations per instruction cycle. The MCU-style programming model and
optimized instruction set allow straightforward generation of efficient, compact DSP and control code.
The instruction set is also highly efficient for C/C++ Compilers to enable rapid development of optimized
control applications.
The 56F807 supports program execution from either internal or external memories. Two data operands can
be accessed from the on-chip Data RAM per instruction cycle. The 56F807 also provides two external
dedicated interrupt lines and up to 32 General Purpose Input/Output (GPIO) lines, depending on peripheral
configuration.
The 56F807 controller includes 60K, 16-bit words of Program Flash and 8K words of Data Flash (each
programmable through the JTAG port) with 2K words of Program RAM and 4K words of Data RAM. It
also supports program execution from external memory.

Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not
available from Freescale for import or sale in the United States prior to September 2010: DSP56F807VF80, DSP56F807VF80E
A total of 2K words of Boot Flash is incorporated for easy customer-inclusion of field-programmable
software routines that can be used to program the main Program and Data Flash memory areas. Both
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 56F807 is the inclusion of two Pulse Width Modulator (PWM)
modules. These modules each incorporate three complementary, individually programmable PWM signal
outputs (each module is also capable of supporting six independent PWM functions, for a total of 12 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 PWMs incorporate fault protection and cycle-by-cycle current limiting
with sufficient output drive capability to directly drive standard optoisolators. A “smoke-inhibit”,
write-once protection feature for key parameters is also included. A patented PWM waveform distortion
correction circuit is also provided. Each PWM is double-buffered and includes interrupt controls to permit
integral reload rates to be programmable from 1 to 16. The PWM modules provide a reference output to
synchronize the analog-to-digital converters.
The 56F807 incorporates two separate Quadrature Decoders 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. An 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 two Serial
Communications Interfaces (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), an internal interrupt controller, and
14 dedicated GPIO lines are also included on the 56F807.

Signal Description
Reset Output—This output reflects the internal reset state of the
chip.
Reset—This input is a direct hardware reset on the processor. When
RESET is asserted low, the device is initialized and placed in the
Reset state. A Schmitt trigger input is used for noise immunity. When
the RESET pin is deasserted, the initial chip operating mode is
latched from the EXTBOOT pin. The internal reset signal will be
deasserted synchronous with the internal clocks, after a fixed number
of internal clocks.
To ensure complete hardware reset, RESET and TRST should be
asserted together. The only exception occurs in a debugging
environment when a hardware device reset is required and it is
necessary not to reset the OnCE/JTAG module. In this case, assert
RESET, but do not assert TRST.

Part 3 Specifications
3.1 General Characteristics
The 56F807 is fabricated in high-density CMOS with 5V-tolerant TTL-compatible digital inputs. The term
“5V-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 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

The 56F807 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.

Notes:
1.
Theta-JA determined on 2s2p test boards is frequently lower than would be observed in an application.
Determined on 2s2p thermal test board.
2.
Junction to ambient thermal resistance, Theta-JA (RθJA) was simulated to be equivalent to the JEDEC
specification JESD51-2 in a horizontal configuration in natural convection. Theta-JA was also simulated on
a thermal test board with two internal planes (2s2p where “s” is the number of signal layers and “p” is the
number of planes) per JESD51-6 and JESD51-7. The correct name for Theta-JA for forced convection or with
the non-single layer boards is Theta-JMA.
3.
Junction to case thermal resistance, Theta-JC (RθJC ), was simulated to be equivalent to the measured values
using the cold plate technique with the cold plate temperature used as the “case” temperature. The basic cold
plate measurement technique is described by MIL-STD 883D, Method 1012.1. This is the correct thermal
metric to use to calculate thermal performance when the package is being used with a heat sink.

DC Electrical Characteristics
4.
Thermal Characterization Parameter, Psi-JT (ΨJT ), is the “resistance” from junction to reference point
thermocouple on top center of case as defined in JESD51-2. ΨJT is a useful value to use to estimate junction
temperature in steady state customer environments.
5.
Junction temperature is a function of on-chip power dissipation, package thermal resistance, mounting site
(board) temperature, ambient temperature, air flow, power dissipation of other components on the board, and
board thermal resistance.

4. PWM pin output sink current measured with 50% duty cycle.
5. IDDT = IDD + IDDA (Total supply current for VDD + VDDA)
6. Run (operating) IDD measured using 8MHz clock source. All inputs 0.2V from rail; outputs unloaded. All ports configured as inputs;
measured with all modules enabled.
7. Wait IDD measured using external square wave clock source (fosc = 8MHz) into XTAL; all inputs 0.2V from rail; no DC loads; less
than 50pF on all outputs. CL = 20pF on EXTAL; all ports configured as inputs; EXTAL capacitance linearly affects wait IDD; measured
with PLL enabled.
8. This low voltage interrupt monitors the VDDA external power supply. VDDA is generally connected to the same potential as VDD via
separate traces. If VDDA drops below VEIO, an interrupt is generated. Functionality of the device is guaranteed under transient conditions when VDDA>VEIO (between the minimum specified VDD and the point when the VEIO interrupt is generated).
9. This low voltage interrupt monitors the internally regulated core power supply. If the output from the internal voltage is regulator
drops below VEIC, an interrupt is generated. Since the core logic supply is internally regulated, this interrupt will not be generated unless
the external power supply drops below the minimum specified value (3.0V).
10. Power–on reset occurs whenever the internally regulated 2.5V digital supply drops below 1.5V typical. While power is ramping up,
this signal remains active as long as the internal 2.5V is below 1.5V typical, no matter how long the ramp-up rate is. The internally
regulated voltage is typically 100mV less than VDD during ramp-up until 2.5V is reached, at which time it self-regulates.

3.4 External Clock Operation
The 56F807 system clock can be derived from an external crystal or an external system clock signal. To
generate a reference frequency using the internal oscillator, a reference crystal must be connected between
the EXTAL and XTAL pins.
3.4.1
Crystal Oscillator
The internal oscillator is also designed to interface with a parallel-resonant crystal resonator in the
frequency range specified for the external crystal in Table 3-9. In Figure 3-7 a recommended crystal
oscillator circuit is shown. Follow the crystal supplier’s recommendations when selecting a crystal, since
crystal parameters determine the component values required to provide maximum stability and reliable
start-up. The crystal and associated components should be mounted as close as possible to the EXTAL
and XTAL pins to minimize output distortion and start-up stabilization time. The internal 56F80x
oscillator circuitry is designed to have no external load capacitors present. As shown in Figure 3-8 no
external load capacitors should be used.
The 56F80x components internally are modeled as a parallel resonant oscillator circuit to provide a
capacitive load on each of the oscillator pins (XTAL and EXTAL) of 10pF to 13pF over temperature and
process variations. Using a typical value of internal capacitance on these pins of 12pF and a value of 3pF

available from Freescale for import or sale in the United States prior to September 2010: DSP56F807VF80, DSP56F807VF80E
as a typical circuit board trace capacitance the parallel load capacitance presented to the crystal is 9pF as
determined by the following equation:
CL1 * CL2
CL =
CL1 + CL2
12 * 12
+ Cs =
+ 3 = 6 + 3 = 9pF
12 + 12
This is the value load capacitance that should be used when selecting a crystal and determining the actual
frequency of operation of the crystal oscillator circuit.

Ceramic Resonator
It is also possible to drive the internal oscillator with a ceramic resonator, assuming the overall system
design can tolerate the reduced signal integrity. In Figure 3-8, a typical ceramic resonator circuit is
shown. Refer to supplier’s recommendations when selecting a ceramic resonator and associated
components. The resonator and components should be mounted as close as possible to the EXTAL and
XTAL pins. The internal 56F80x oscillator circuitry is designed to have no external load capacitors
present. As shown in Figure 3-7 no external load capacitors should be used.

1. If Wakeup glitch filter is enabled during the design initialization and also CAN is put into SLEEP mode then, any bus event
(on MSCAN_RX pin) whose duration is less than 5 microseconds is filtered away. However, a valid CAN bus wakeup detection
takes place for a wakeup pulse equal to or greater than 5 microseconds. The number 5 microseconds originates from the fact
that the CAN wakeup message consists of 5 dominant bits at the highest possible baud rate of 1Mbps.

Thermal Design Considerations

Part 5 Design Considerations
5.1 Thermal Design Considerations
An estimation of the chip junction temperature, TJ, in °C can be obtained from the equation:
Equation 1:
T J = T A + ( P D × R θJA )
Where:
TA = ambient temperature °C
RθJA = package junction-to-ambient thermal resistance °C/W
PD = 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:
R θJA = R θJC + R θCA
Where:
RθJA = package junction-to-ambient thermal resistance °C/W
RθJC = package junction-to-case thermal resistance °C/W
RθCA = package case-to-ambient thermal resistance °C/W
RθJC is device-related and cannot be influenced by the user. The user controls the thermal environment to
change the case-to-ambient thermal resistance, RθCA. 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 RθJA 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.

available from Freescale for import or sale in the United States prior to September 2010: DSP56F807VF80, DSP56F807VF80E
•
•
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.
Use the value obtained by the equation (TJ – TT)/PD where TT 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.
5.2 Electrical Design Considerations
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.
Use the following list of considerations to assure correct operation:
•
Provide a low-impedance path from the board power supply to each VDD pin on the controller, and from the
board ground to each VSS pin.
•
The minimum bypass requirement is to place 0.1 μF 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 VDD/VSS pairs, including VDDA/VSSA. Ceramic and tantalum capacitors tend to provide better
performance tolerances.

•
•
•
•
Ensure that capacitor leads and associated printed circuit traces that connect to the chip VDD and VSS pins
are less than 0.5 inch per capacitor lead.
Bypass the VDD and VSS layers of the PCB with approximately 100 μF, 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 VDD and VSS circuits.
•
Take special care to minimize noise levels on the VREF, VDDA and VSSA 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.
