56F8006/56F8002 Signal Pins
After reset, each pin is configured for its primary function (listed first). Any alternate functionality must be programmed via the
GPIO module’s peripheral enable registers (GPIO_x_PER) and SIM module’s (GPS_xn) GPIO peripheral select registers. If
CLKIN or XTAL is selected as device external clock input, the CLK_MOD bit in the OCCS oscillator control register (OSCTL)
needs to be set too. EXT_SEL bit in OSCTL selects CLKIN or XTAL.

Introduction
The 56F8006/56F8002 device is based on the 56800E core. It uses a dual Harvard-style architecture with two independent
memory spaces for Data and Program. On-chip RAM is shared by both data and program spaces and flash memory is used only
in program space.
This section provides memory maps for:
• Program address space, including the interrupt vector table
• Data address space, including the EOnCE memory and peripheral memory maps
On-chip memory sizes for the device are summarized in Table 6. Flash memories’ restrictions are identified in the “Use
Restrictions” column of Table 6.

Program Map
The 56F8006/56F8002 series provide up to 16 KB on-chip flash memory. It primarily accesses through the program memory
buses (PAB; PDB). PAB is used to select program memory addresses; instruction fetches are performed over PDB. Data can be
read and written to program memory space through primary data memory buses: CDBW for data write and CDBR for data read.
Accessing program memory space over the data memory buses takes longer access time compared to accessing data memory
space. The special MOVE instructions are provided to support these accesses. The benefit is that non time critical constants or
tables can be stored and accessed in program memory.
The program memory map is shown in Table 7 and Table 8.

Data Map
The 56F8006/56F8002 series contain a dual access memory. It can be accessed from core primary data buses (XAB1; CDBW;
CDBR) and secondary data buses (XAB2; XDB2). Addresses in data memory are selected on the XAB1 and XAB2 buses. Byte,
word, and long data transfers occur on the 32-bit CDBR and CDBW buses. A second 16-bit read operation can be performed
in parallel on the XDB2 bus.
Peripheral registers and on-chip JTAG/EOnCE controller registers are memory-mapped into data memory access. A special
direct address mode is supported for accessing a first 64-location in data memory by using a single word instruction.
The data memory map is shown in Table 9.

Interrupt Vector Table and Reset Vector
The location of the vector table is determined by the vector base address register (VBA). The value in this register is used as
the upper 14 bits of the interrupt vector VAB[20:0]. The lower seven bits are determined based on the highest priority interrupt
and are then appended onto VBA before presenting the full VAB to the core. Please see the MC56F8006 Peripheral Reference
Manual for detail. The reset startup addresses of 56F8002 and 56F8006 are different.
•
•
56F8006 startup address is located at 0x00 0000. The reset value of VBA is reset to a value of 0x0000 that corresponds
to address 0x00 0000
56F8002 startup address is located at 0x00 0800. The reset value of VBA is reset to a value of 0x0010 that corresponds
to address 0x00 0800
By default, the chip reset address and COP reset address correspond to vector 0 and 1 of the interrupt vector table. In these
instances, the first two locations in the vector table must contain branch or JMP instructions. All other entries must contain JSR
instructions.
The highest number vector, a user assignable vector USER6 (vector 50), can be defined as a fast interrupt if the instruction
located in this vector location is not a JSR or BSR instruction. Please see section 9.3.3.3 of DSP56800E 16-Bit Core Reference
Manual for detail.

General System Control Information
6.1
Overview
This section discusses power pins, reset sources, interrupt sources, clock sources, the system integration module (SIM), ADC
synchronization, and JTAG/EOnCE interfaces.
6.2
Power Pins
VDD, VSS and VDDA, VSSA are the primary power supply pins for the devices. This voltage source supplies power to all on-chip
peripherals, I/O buffer circuitry and to internal voltage regulators. Device has multiple internal voltages provide regulated
lower-voltage source for the peripherals, core, memory, and on-chip relaxation oscillators.
Typically, there are at least two separate capacitors across the power pins to bypass the glitches and provide bulk charge storage.
In this case, there should be a bulk electrolytic or tantalum capacitor, such as a 10 μF tantalum capacitor, to provide bulk charge
storage for the overall system and a 0.1 μF ceramic bypass capacitor located as near to the device power pins as practical to
suppress high-frequency noise. Each pin must have a bypass capacitor for best noise suppression.
VDDA and VSSAare the analog power supply pins for the device. This voltage source supplies power to the ADC, PGA, and
CMP modules. A 0.1 μF ceramic bypass capacitor should be located as near to the device VDDA and VSSA pins as practical to
suppress high-frequency noise. VDDA and VSSA are also the voltage reference high and voltage reference low inputs,
respectively, for the ADC module.
6.3
Reset
Resetting the device provides a way to start processing from a known set of initial conditions. During reset, most control and
status registers are forced to initial values and the program counter is loaded from the reset vector. On-chip peripheral modules
are disabled and I/O pins are initially configured as the reset status shown in Table 5. The 56F8006/56F8002 has the following
sources for reset:
•
•
•
•
•
•
•
Power-on reset (POR)
Partial power down reset (PPD)
Low-voltage detect (LVD)
External pin reset (EXTR)
Computer operating properly loss of reference reset (COP_LOR)
Computer operating properly time-out reset (COP_CPU)
Software Reset (SWR)
Each of these sources has an associated bit in the reset status register (RSTAT) in the system integration module (SIM).
The external pin reset function is shared with an GPIO port A7 on the RESET/GPIOA7 pin. The reset function is enabled
following any reset of the device. Bit 7 of GPIOA_PER register must be cleared to use this pin as an GPIO port pin. When
enabled as the RESET pin, an internal pullup device is automatically enabled.
6.4
On-chip Clock Synthesis
The on-chip clock synthesis (OCCS) module allows designers using an internal relaxation oscillator, an external crystal, or an
external clock to run 56F8000 family devices at user-selectable frequencies up to 32 MHz.
The features of OCCS module include:
•
•
•
Ability to power down the internal relaxation oscillator or crystal oscillator
Ability to put the internal relaxation oscillator into standby mode
Ability to power down the PLL

General System Control Information

•
Provides a 3X system clock that operates at three times the system clock to PWM, timer, and SCI modules
Safety shutdown feature is available if the PLL reference clock is lost
Can be driven from an external clock source
The clock generation module provides the programming interface for the PLL, internal relaxation oscillator, and crystal
oscillator. It also provides a postscaler to divide clock frequency down by 1, 2, 4, 8, 16, 32, 64, 128, 256 before feeding to the
SIM. The SIM is responsible for further dividing these frequencies by two, which ensures a 50% duty cycle in the system clock
output. For detail, see the OCCS chapter in the MC56F8006 Peripheral Reference Manual.
6.4.1
Internal Clock Source
An internal relaxation oscillator can supply the reference frequency when an external frequency source or crystal is not used. It
is optimized for accuracy and programmability while providing several power-saving configurations that accommodate
different operating conditions. The internal relaxation oscillator has little temperature and voltage variability. To optimize
power, the internal relaxation oscillator supports a run state (8 MHz), standby state (400 kHz), and a power-down state.
During a boot or reset sequence, the relaxation oscillator is enabled by default (the PRECS bit in the PLLCR word is set to 0).
Application code can then also switch to the external clock source and power down the internal oscillator, if desired. If a
changeover between internal and external clock sources is required at power-on, ensure that the clock source is not switched
until the desired external clock source is enabled and stable.
To compensate for variances in the device manufacturing process, the accuracy of the relaxation oscillator can be incrementally
adjusted to within + 0.078% of 8 MHz by trimming an internal capacitor. Bits 0–9 of the OSCTL (oscillator control) register
allow you to set in an additional offset (trim) to this preset value to increase or decrease capacitance. Each unit added or
subtracted changes the output frequency by about 0.078% of 8 MHz, allowing incremental adjustment until the desired
frequency accuracy is achieved.
The center frequency of the internal oscillator is calibrated at the factory to 8 MHz and the TRIM value is stored in the flash
information block and loaded to the FMOPT1 register at reset. When using the relaxation oscillator, the boot code should read
the FMOPT1 register and set this value as OSCTL TRIM. For further information, see the MC56F8006 Peripheral Reference
Manual.
6.4.2
Crystal Oscillator/Ceramic Resonator
The internal crystal oscillator circuit is designed to interface with a parallel-resonant crystal resonator in the frequency range,
specified for the external crystal, of 32.768 kHz (Typ) or 1–16 MHz. A ceramic resonator can be substituted for the 1–16 MHz
range. When used to supply a source to the internal PLL, the recommended crystal/resonator is in the 4 MHz to 8 MHz
(recommend 8 MHz) range to achieve optimized PLL performance. Oscillator circuits are shown in Figure 9, Figure 10, and
Figure 11. Follow the crystal supplier’s recommendations when selecting a crystal, because crystal parameters determine the
component values required to provide maximum stability and reliable start-up. The load capacitance values used in the
oscillator circuit design should include all stray layout capacitances. The crystal and associated components should be mounted
as near as possible to the EXTAL and XTAL pins to minimize output distortion and start-up stabilization time. When using
low-frequency, low-power mode, the only external component is the crystal itself. In the other oscillator modes, load capacitors
(Cx, Cy) and feedback resistor (RF) are required. In addition, a series resistor (RS) may be used in high-gain modes.
Recommended component values are listed in Table 27.

The recommended method of connecting an external clock is illustrated in Figure 12. The external clock source is connected to
XTAL and the EXTAL pin is grounded or configured as GPIO while CLK_MOD bit in OSCTL register is set. The external
clock input must be generated using a relatively low impedance driver with maximum frequency less than 8 MHz.

Interrupt Controller
The 56F8006/56F8002 interrupt controller (INTC) module arbitrates the various interrupt requests (IRQs). The INTC signals
to the 56800E core when an interrupt of sufficient priority exists and what address to jump to to service this interrupt.
The interrupt controller contains registers that allow up to three interrupt sources to be set to priority level 1 and other up to
three interrupt sources to be set to priority level 2. By default, all peripheral interrupt sources are set to priority level 0. Next,
all of the interrupt requests of a given level are priority encoded to determine the lowest numeric value of the active interrupt
requests for that level. Within a given priority level, the lowest vector number is the highest priority and the highest vector
number is the lowest.
The highest vector number, a user assignable vector USER6 (vector 50), can be defined as a fast interrupt if the instruction
located in this vector location is not a JSR or BSR instruction. Please see section 9.3.3.3 of DSP56800E 16-Bit Core Reference
Manual for detail.
6.6
System Integration Module (SIM)
The SIM module is a system catchall for the glue logic that ties together the system-on-chip. It controls distribution of resets
and clocks and provides a number of control features including the pin muxing control; inter-module connection control (for
example connecting comparator output to PWM fault input); individual peripheral enable/disable; PWM, timer, and SCI clock
rate control; enabling peripheral operation in stop mode; port configuration overwrite protection. For further information, see
the MC56F8006 Peripheral Reference Manual.

Joint Test Action Group (JTAG)/Enhanced On-Chip Emulator
(EOnCE)
The DSP56800E Family includes extensive integrated support for application software development and real-time debugging.
Two modules, the Enhanced On-Chip Emulation module (EOnCE) and the core test access port (TAP, commonly called the
JTAG port), work together to provide these capabilities. Both are accessed through a common 4-pin JTAG/EOnCE interface.
These modules allow you to insert the 56F8006/56F8002 into a target system while retaining debug control. This capability is
especially important for devices without an external bus, because it eliminates the need for a costly cable to bring out the
footprint of the chip, as is required by a traditional emulator system.
The DSP56800E EOnCE module is a Freescale-designed module used to develop and debug application software used with the
chip. This module allows non-intrusive interaction with the CPU and is accessible through the pins of the JTAG interface or by
software program control of the DSP56800E core. Among the many features of the EOnCE module is the support for data
communication between the controller and the host software development and debug systems in real-time program execution.
Other features allow for hardware breakpoints, the monitoring and tracking of program execution, and the ability to examine
and modify the contents of registers, memory, and on-chip peripherals, all in a special debug environment. No user-accessible
resources need to be sacrificed to perform debugging operations.
The DSP56800E JTAG port is used to provide an interface for the EOnCE module to the DSP JTAG pins. Joint Test Action
Group (JTAG) boundary scan is an IEEE 1149.1 standard methodology enabling access to test features using a test access port
(TAP). A JTAG boundary scan consists of a TAP controller and boundary scan registers. Please contact your Freescale sales
representative or authorized distributor for device-specific BSDL information.
NOTE
In normal operation, an external pullup on the TMS pin is highly recommend to place the
JTAG state machine in reset state if this pin is not configured as GPIO.

Security Features
The 56F8006/56F8002 offers security features intended to prevent unauthorized users from reading the contents of the flash
memory (FM) array. The 56F8006/56F8002’s flash security consists of several hardware interlocks that prevent unauthorized
users from gaining access to the flash array.
After flash security is set, an authorized user can be enabled to access on-chip memory if a user-defined software subroutine,
which reads and transfers the contents of internal memory via peripherals, is included in the application software. This
application software could communicate over a serial port, for example, to validate the authenticity of the requested access, then
grant it until the next device reset. The inclusion of such a back door technique is at the discretion of the system designer.

Security Features
7.1
Operation with Security Enabled
After you have programmed flash with the application code, or as part of the programming of the flash with the application
code, the 56F8006/56F8002 can be secured by programming the security word, 0x0002, into program memory location 0x00
1FF7. This can also be effected by use of the CodeWarrior IDE menu flash lock command. This nonvolatile word keeps the
device secured after reset, caused, for example, by a power-down of the device. Refer to the flash memory chapter in the
MC56F8006 Peripheral Reference Manual for detail. When flash security mode is enabled, the 56F8006/56F8002 disables the
core EOnCE debug capabilities. Normal program execution is otherwise unaffected.
7.2
Flash Access Lock and Unlock Mechanisms
There are several methods that effectively lock or unlock the on-chip flash.
7.2.1
Disabling EOnCE Access
On-chip flash can be read by issuing commands across the EOnCE port, which is the debug interface for the 56800E CPU. The
TCK, TMS, TDO, and TDI pins comprise a JTAG interface onto which the EOnCE port functionality is mapped. When the
device boots, the chip-level JTAG TAP (test access port) is active and provides the chip’s boundary scan capability and access
to the ID register, but proper implementation of flash security blocks any attempt to access the internal flash memory via the
EOnCE port when security is enabled. This protection is effective when the device comes out of reset, even prior to the
execution of any code at startup.
7.2.2
Flash Lockout Recovery Using JTAG
If the device is secured, one lockout recovery mechanism is the complete erasure of the internal flash contents, including the
configuration field, thus disabling security (the protection register is cleared). This does not compromise security, as the entire
contents of your secured code stored in flash are erased before security is disabled on the device on the next reset or power-up
sequence.
To start the lockout recovery sequence via JTAG, the JTAG public instruction (LOCKOUT_RECOVERY) must first be shifted
into the chip-level TAP controller’s instruction register. After the LOCKOUT_RECOVERY instruction has been shifted into
the instruction register, the clock divider value must be shifted into the corresponding 7-bit data register. After the data register
has been updated, you must transition the TAP controller into the RUN-TEST/IDLE state for the lockout sequence to
commence. The controller must remain in this state until the erase sequence is complete. Refer to the MC56F8006 Peripheral
Reference Manual for detail, or contact Freescale.
NOTE
After the lockout recovery sequence has completed, you must reset the JTAG TAP
controller and device to return to normal unsecured operation. Power-on reset resets both
too.
7.2.3
Flash Lockout Recovery Using CodeWarrior
CodeWarrior can unlock a device by selecting the Debug menu, then selecting DSP56800E, followed by Unlock Flash. Another
mechanism is also built into CodeWarrior using the device’s memory configuration file. The command
“Unlock_Flash_on_Connect 1” in the .cfg file accomplishes the same task as using the Debug menu.
This lockout recovery mechanism is the complete erasure of the internal flash contents, including the configuration field, thus
disabling security (the protection register is cleared).

Specifications
7.2.4
7.2.4.1
Flash Lockout Recovery without Mass Erase
Without Presenting Back Door Access Keys to the Flash Unit
A user can un-secure a secured device by programming the word 0x0000 into program flash location 0x00 1FF7. After
completing the programming, the JTAG TAP controller and the device must be reset to return to normal unsecured operation.
You are responsible for directing the device to invoke the flash programming subroutine to reprogram the word 0x0000 into
program flash location 0x00 1FF7. This is done by, for example, toggling a specific pin or downloading a user-defined key
through serial interfaces.
NOTE
Flash contents can be programmed only from 1s to 0s.
7.2.4.2
Presenting Back Door Access Key to the Flash Unit
It is possible to temporarily bypass the security through a back door access scheme, using a 4-word key, to temporarily unlock
of the flash. A back door access requires support from the embedded software. This software would typically permit an external
user to enter a four word code through one of the communications interfaces and then use it to attempt the unlock sequence. If
your input matches the four word code stored at location 0x00 1FFC–0x00 1FFF in the flash memory, the part immediately
becomes unsecured (at runtime) and you can access internal memory via JTAG/EOnCE port. Refer to the MC56F8006
Peripheral Reference Manual for detail. The key must be entered in four consecutive accesses to the flash, so this routine should
be designed to run in RAM.
7.3
Product Analysis
The recommended method of unsecuring a secured device for product analysis of field failures is via the method described in
Section 7.2.4.2, “Presenting Back Door Access Key to the Flash Unit.” The customer would need to supply technical support
with the details of the protocol to access the subroutines in flash memory. An alternative method for performing analysis on a
secured device would be to mass-erase and reprogram the flash with the original code, but modify the security word or not
program the security word.

temperature over the following supply ranges: VSS = VSSA = 0V, VDD = VDDA = 3.0–3.6 V, CL < 50 pF, fOP = 32 MHz
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.

Absolute Maximum Ratings
Absolute maximum ratings are stress ratings only, and functional operation at the maxima is not guaranteed. Stress beyond the
limits specified Table 12 may affect device reliability or cause permanent damage to the device. For functional operating
conditions, refer to the remaining tables in this section.
This device contains circuitry protecting against damage due to high static voltage or electrical fields; however, take normal
precautions 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 logic voltage level (for instance, either VSS or VDD) or the
programmable pullup resistor associated with the pin is enabled.

Input must be current limited to the value specified. To determine the value of the required current-limiting resistor, calculate
resistance values for positive (VDD) and negative (VSS) clamp voltages, then use the larger of the two resistance values.
2 All functional non-supply pins are internally clamped to V
SS and VDD.
3 Power supply must maintain regulation within operating VDD range during instantaneous and operating maximum current
conditions. If positive injection current (VIn > VDD) is greater than IDD, the injection current may flow out of VDD and could result
in external power supply going out of regulation. Ensure external VDD loads shunt current greater than maximum injection
current. This is the greatest risk when the MCU is not consuming power. Examples are: if no system clock is present or if the
clock rate is low (which would reduce overall power consumption).
8.2.1
ESD Protection and Latch-Up Immunity
Although damage from electrostatic discharge (ESD) is much less common on these devices than on early CMOS circuits, use
normal handling precautions to avoid exposure to static discharge. Qualification tests are performed to ensure that these devices
can withstand exposure to reasonable levels of static without suffering any permanent damage.

Specifications
All ESD testing is in conformity with AEC-Q100 Stress Test Qualification for Automotive Grade Integrated Circuits. During
the device qualification ESD stresses were performed for the human body model (HBM), the machine model (MM), and the
charge device model (CDM).
A device is defined as a failure if after exposure to ESD pulses the device no longer meets the device specification. Complete
DC parametric and functional testing is performed per the applicable device specification at room temperature followed by hot
temperature, unless specified otherwise in the device specification.

Thermal Characteristics
This section provides information about operating temperature range, power dissipation, and package thermal resistance. Power
dissipation on I/O pins is usually small compared to the power dissipation in on-chip logic and voltage regulator circuits, and
it is user-determined rather than being controlled by the MCU design. To take PI/O into account in power calculations, determine
the difference between actual pin voltage and VSS or VDD and multiply by the pin current for each I/O pin. Except in cases of
unusually high pin current (heavy loads), the difference between pin voltage and VSS or VDD will be very small.

An externally supplied reference clock should be as free as possible from any phase jitter for the PLL to work correctly. The
PLL is optimized for 8 MHz input.
The core system clock operates at 1/6 of the PLL output frequency.
This is the time required after the PLL is enabled to ensure reliable operation.
From powerdown to powerup state at 32 MHz system clock state.
This is measured on the CLKO signal (programmed as system clock) over 264 system clocks at 32 MHz system clock
frequency and using an 8 MHz oscillator frequency.

The master mode I2C deasserts ACK of an address byte simultaneously with the falling edge of SCL. If no slaves
acknowledge this address byte, a negative hold time can result, depending on the edge rates of the SDA and SCL
lines.
The maximum tHD; DAT must be met only if the device does not stretch the LOW period (tLOW) of the SCL signal.
Set-up time in slave-transmitter mode is 1 IPBus clock period, if the TX FIFO is empty.
A Fast mode I2C bus device can be used in a Standard mode I2C bus system, but the requirement tSU; DAT > = 250 ns
must then be met. This is automatically the case if the device does not stretch the LOW period of the SCL signal. If
such a device does stretch the LOW period of the SCL signal, it must output the next data bit to the SDA line
trmax + tSU; DAT = 1000 + 250 = 1250 ns (according to the Standard mode I2C bus specification) before the SCL line is
released.
Cb = total capacitance of the one bus line in pF.

Optimize Power Consumption
See Section 8.6, “Supply Current Characteristics,” for a list of IDD requirements for the 56F8006/56F8002. This section
provides additional detail that can be used to optimize power consumption for a given application.
MC56F8006/MC56F8002 Digital Signal Controller, Rev. 2
Freescale Semiconductor
65
Specifications
Power consumption is given by the following equation:
Eqn. 1
Total power =
A:
internal [static component]
+B: internal [state-dependent component]
+C:
internal [dynamic component]
+D:
external [dynamic component]
+E:
external [static component]
A, the internal [static] component, is comprised of the DC bias currents for the oscillator, leakage currents, PLL, and voltage
references. These sources operate independently of processor state or operating frequency.
B, the internal [state-dependent] component, reflects the supply current required by certain on-chip resources only when those
resources are in use. These include RAM, flash memory, and the ADCs.
C, the internal [dynamic] component, is classic C*V2*F CMOS power dissipation corresponding to the 56800E core and
standard cell logic.
D, the external [dynamic] component, reflects power dissipated on-chip as a result of capacitive loading on the external pins of
the chip. This is also commonly described as C*V2*F, although simulations on two of the I/O cell types used on the 56800E
reveal that the power-versus-load curve does have a non-zero Y-intercept.

Power due to capacitive loading on output pins is (first order) a function of the capacitive load and frequency at which the
outputs change. Table 38 provides coefficients for calculating power dissipated in the I/O cells as a function of capacitive load.
In these cases:
TotalPower = Σ((Intercept + Slope*Cload)*frequency/10 MHz)
Eqn. 2
where:
•
•
•
Summation is performed over all output pins with capacitive loads
Total power is expressed in mW
Cload is expressed in pF
Because of the low duty cycle on most device pins, power dissipation due to capacitive loads was found to be fairly low when
averaged over a period of time.
E, the external [static component], reflects the effects of placing resistive loads on the outputs of the device. Sum the total of
all V2/R or IV to arrive at the resistive load contribution to power. Assume V = 0.5 for the purposes of these rough calculations.
For instance, if there is a total of eight PWM outputs driving 10 mA into LEDs, then P = 8*0.5*0.01 = 40 mW.
In previous discussions, power consumption due to parasitics associated with pure input pins is ignored, as it is assumed to be
negligible.

Design Considerations
9.1
Thermal Design Considerations
An estimation of the chip junction temperature, TJ, can be obtained from the equation:
TJ = TA + (RθJΑ x PD)
Eqn. 3
where:
TA
=
Ambient temperature for the package (oC)
= Junction-to-ambient thermal resistance (oC/W)
RθJΑ
=
PD
Power dissipation in the package (W)
The junction-to-ambient thermal resistance is an industry-standard value that provides a quick and easy estimation of thermal
performance. Unfortunately, there are two values in common usage: the value determined on a single-layer board and the value
obtained on a board with two planes. For packages such as the PBGA, these values can be different by a factor of two. Which
value is closer to the application depends on the power dissipated by other components on the board. The value obtained on a
single layer board is appropriate for the tightly packed printed circuit board. The value obtained on the board with the internal
planes is usually appropriate if the board has low-power dissipation and the components are well separated.
When a heat sink is used, the thermal resistance is expressed as the sum of a junction-to-case thermal resistance and a
case-to-ambient thermal resistance:
RθJA = RθJC + RθCA
Eqn. 4
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 adjusted. You control the thermal environment to change the case to ambient thermal
resistance, RθCA. For instance, you can change the size of the heat sink, the air flow around the device, the interface material,
the mounting arrangement on printed circuit board, or change the thermal dissipation on the printed circuit board surrounding
the device.
To determine the junction temperature of the device in the application when heat sinks are not used, the thermal characterization
parameter (ΨJT) 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:
TJ = TT + (ΨJT x PD)
Eqn. 5
where:
TT
=
Thermocouple temperature on top of package (oC)
ΨJT
=
Thermal characterization parameter (oC/W)
PD
=
Power dissipation in package (W)
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 1 mm of wire extending from the

Design Considerations
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.
9.2
Electrical Design Considerations
CAUTION
This device contains protective circuitry to guard against damage due to high static voltage
or electrical fields. However, take normal precautions 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 of the 56F8006/56F8002:
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
Provide a low-impedance path from the board power supply to each VDD pin on the 56F8006/56F8002 and from the
board ground to each VSS (GND) pin.
The minimum bypass requirement is to place 0.01–0.1µF capacitors positioned as near 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 tolerances.
Ensure that capacitor leads and associated printed circuit traces that connect to the chip VDD and VSS (GND) pins are
as short as possible.
Bypass the VDD and VSS with approximately 100 µF, plus the number of 0.1 µF ceramic capacitors.
PCB trace lengths should be minimal for high-frequency signals.
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.
Using separate power planes for VDD and VDDA and separate ground planes for VSS and VSSA are recommended.
Connect the separate analog and digital power and ground planes as near as possible to power supply outputs. If an
analog circuit and digital circuit are powered by the same power supply, you should connect a small inductor or ferrite
bead in serial with VDDA and VSSA traces.
Physically separate analog components from noisy digital components by ground planes. Do not place an analog trace
in parallel with digital traces. Place an analog ground trace around an analog signal trace to isolate it from digital traces.
Because the flash memory is programmed through the JTAG/EOnCE port, SPI, SCI, or I2C, the designer should
provide an interface to this port if in-circuit flash programming is desired.
If desired, connect an external RC circuit to the RESET pin. The resistor value should be in the range of 4.7 kΩ–10 kΩ;
the capacitor value should be in the range of 0.22 µF–4.7 µF.
Configuring the RESET pin to GPIO output in normal operation in a high-noise environment may help to improve the
performance of noise transient immunity.
Add a 2.2 kΩ external pullup on the TMS pin of the JTAG port to keep EOnCE in a restate during normal operation if
JTAG converter is not present.
During reset and after reset but before I/O initialization, all I/O pins are at input state with internal pullup enabled. The
typical value of internal pullup is around 33 kΩ. These internal pullups can be disabled by software.
To eliminate PCB trace impedance effect, each ADC input should have a no less than 33 pF 10 Ω RC filter.
External clamp diodes on analog input pins are recommended.

Interrupt Vector Table
Appendix A
Interrupt Vector Table
Table 40 provides the 56F8006/56F8002’s reset and interrupt priority structure, including on-chip peripherals. The table is
organized with higher-priority vectors at the top and lower-priority interrupts lower in the table. As indicated, the priority of an
interrupt can be assigned to different levels, allowing some control over interrupt priorities. All level 3 interrupts are serviced
before level 2 and so on. For a selected priority level, the lowest vector number has the highest priority.
The location of the vector table is determined by the vector base address (VBA). Please see the MC56F8006 Peripheral
Reference Manual for detail.
By default, the chip reset address and COP reset address correspond to vector 0 and 1 of the interrupt vector table. In these
instances, the first two locations in the vector table must contain branch or JMP instructions. All other entries must contain JSR
instructions.
