2)Availability of port pin alternate functions depends on product selection.
1. See the I/O pad electrical characteristics in the device data sheet for details.
2. All medium and fast pads are in slow configuration by default at reset and can be configured as fast or medium. For example,
Fast/Medium pad will be Medium by default at reset. Similarly, Slow/Medium pad will be Slow by default. Only exception is PC[1]
which is in medium configuration by default (refer to PCR.SRC in the reference manual, Pad Config uration Registers
(PCR0—PCR198)).

1Alternate functions are chosen by setting the values of the PCR.PA bitfields inside the SIUL module. PCR.PA =
000 AF0; PCR.PA = 001 AF1; PCR.P A = 010 AF2; PCR.P A = 011 AF3; PCR.P A = 100 AL T4. This is
intended to select the output functions; to use one of the input functions, the PCR.IBE bit must be written to ‘1’,
regardless of the values selected in the PCR.P A bitfields. For this reason, the value corresponding to an input only

2Multiple inputs are routed to all respective modules internally. The input of some modules must be configured by
setting the values of the PSMIO.PADSELx bitfields inside the SIUL module.
3NMI[0] and NMI[1] have a higher priority than alternate functions. When NMI is selected, the PCR.PA field is
ignored.
4SXOSC’s OSC32k_XT AL and OSC32k_EXTAL pins are shared with GPIO functionality . When used as crystal pins,
other functionality of the pin cannot be used and it should be ensured that application never programs OBE and
PUE bit of the corresponding PCR to "1".
5If you want to use OSC32K functionality through PB[8] and PB[9], you must ensure that PB[10] is static in nature
as PB[10] can induce coupling on PB[9] and disturb oscillator frequency.
6Out of reset all the functional pins except PC[0:1] and PH[9:10] are available to the user as GPIO.
PC[0:1] are available as JTAG pins (TDI and TDO respectively).
PH[9:10] are available as JTAG pins (TCK and TMS respectively).
It is up to the user to configure these pins as GPIO when needed.

4Electrical Characteristics
This section contains electrical characteristics of the device as well as temperature and power considerations.
This product contains devices to protect the inputs against damage due to high static voltages. However , it is advisable to take
precautions to avoid application of any voltage higher than the specified maximum rated voltages.
To enhance reliability, unused inputs can be driven to an appropriate logic voltage level (VDD or VSS_HV). This could be done
by the internal pull-up and pull-down, which is provided by the product for most general purpose pins.
The parameters listed in the following tables represent the characteristics of the device and its demands on the system.
In the tables where the device logic provides signals with their respective timing characteristics, the symbol “CC” for Controller
Characteristics is included in the Symbol column.
In the tables where the external system must provide signals with their respective timing characteristics to the device, the symbol
“SR” for System Requirement is included in the Symbol column.
4.1 Parameter classification
The electrical parameters shown in this supplement are guaranteed by various methods. To give the custom er a better
understanding, the classifications listed in Table 5 are used and the parameters are tagged accordingly in the tables where
appropriate.
NOTE
The classification is shown in the column labeled “C” in the parameter tables where
appropriate.
4.2 NVUSRO register
Portions of the device configuration , such as high voltage supply is controlled via bit values in the Non-Volatile User Options
Register (NVUSRO). For a detailed description of the NVUSRO register, see MPC5646C Reference Manual.
7When MBIST is enabled to run ( STCU Enable = 1), the application must not drive or tie PAD[178) (MDO[0]) to 0 V
before the device exits reset (external reset is removed) as the pad is internally driven to 1 to indicate MBIST
operation. When MBIST is not enabled (STCU Enable = 0), there are no restriction as the device does not internally
drive the pad.
8These pins can be configured as Nexus pins during reset by the debugger writing to the Nexus Development
Interface "Port Control Register" rather than the SIUL. S pecifically , the debugger can enable the MDO[7:0], MSEO,
and MCKO ports by programming NDI (PCR[MCKO_EN] or PCR[PSTAT_EN]). MDO[8:11] ports can be enabled
by programming NDI ((PCR[MCKO_EN] and PCR[FPM]) or PCR[PSTAT_EN]).

Most of the time for the applications, PI/O< PINT and may be neglected. On the other hand, PI/O may be significant, if the device
is configured to continuously drive external mo dules and/ or memories.
An approximate relationship between PD and TJ (if PI/O is neglected) is given by:
PD = K / (TJ + 273 °C) Eqn. 2
Therefore, solving equations 1 and 2:
K = PD
(TA + 273 °C) + RJA
PD2Eqn. 3
Where:
K is a constant for the particular part, which may be determined from Equation 3 by measuring PD (at equilibrium)
for a known TA. Using this value of K, the values of PD and TJ may be obtained by solving equ ations 1 and 2
iteratively for any value of TA.
4.6 I/O pad electrical characteristics
4.6.1 I/O pad types
The device provides four main I/O pad types depending on the associated alternate functions:
• Slow pads—These pads are the most common pads, providing a good compromise between transition time and low
electromagnetic emission.
• Medium pads—These pads provide transition fast enough for the serial communication channels with controlled
current to reduce electromagnetic emission.
• Fast pads—These pads provide maximum speed. These are used for improved Nexus debugging capability.
• Input only pads—These pads are associated to ADC channels and 32 kHz low power external crystal oscillator
providing low input leakage.
• Low power pads—These pads are active in standby mo de for wakeup source.
Also, medium/slow and fast/medium pads are available in design which can be configured to behave like a slow/ medi um and
medium/fast pads depending upon the slew-rate control.
Medium and fast pads can use slow configuration to reduce electromagnetic emission, at the cost of reducing AC performance.

4.8 Power management electrical characteristics
4.8.1 Voltage regulator electrical characteristics
The device implements an internal volt age regulator to generate the low volt age core supply VDD_LV from the high voltage
supply VDD_HV_A. The following supplies are involved:
• HV: High voltage external power supply for voltage reg ulator module. This must be prov ided externally through
VDD_HV_A power pin.
• LV: Low voltage internal pow er suppl y for core, FMPLL and Flash digital logic. This is generated by the on-chip
VREG with an external ballast (BCP68 NPN device). It is further split into four main domains to ensure noise isolation
between critical LV modules within the device:
— LV_COR: Low voltage supply for the core. It is also used to provide supply for FMPLL through double bonding.
— LV_CFLA0/CFLA1: Low voltage supply for the two code Flash modules. It is shorted with LV_COR throug h
double bonding.
— LV_DFLA: Low voltage supply for data Flash module. It is short ed with LV_COR through double bonding .
— LV_PLL: Low voltage supply for FM PLL. It is shorted to LV_COR through double bon ding.
Figure 8. Volt age regulator capacitance connection
The internal voltage regulator requires external bulk capacitance (CREGn) to be connected to the device to provide a stable low
voltage digital supply to the device. Also required for stability is the CDEC2 capacitor at ballast collector. This is needed to

minimize sharp injection current when ball ast is tu rni ng ON. Apart from the bulk capacitance, user should connect
EMI/decoupling cap (CREGP) at each VDD_LV/VSS_LV pin pair.
4.8.1.1 Recommendations
• The external NPN driver must be BCP68 type.
•V
DD_LV should be implemented as a power plane from the emitter of the ballast transistor.
•10F capacitors should be connected to the 4 pins closest to the outside of the package and should be evenly
distributed around the package. For BGA packages, the balls should be used are D8, H14, R9, J3–one cap on each side
of package.
— There should be a track direct from the capacitor to this pin (pin also connects to VDD_LV plane). The tracks ESR
should be less than 100 m.
— The remaining VDD_LV pins (exact number will vary with package) sh ould be decoupled with 0.1 F caps,
connected to the pin as per 10 F.
(see Section 4.4, “Recommended operating conditions”).
4.8.2 VDD_BV options
• Opti on 1: VDD_BV shared with VDD_HV_A
VDD_BV must be star routed from VDD_HV_A from the common source. This is to eliminate ballast noise injection on
the MCU.
• Opti on 2: VDD_BV independent of the MCU supply
VDD_BV > 2.6 V for correct functionality . The device is not monitoring this supply hence the external component must
meet the 2.6 V criteria through external monitoring if required.

4.8.3 Voltage monitor electrical characteristics
The device implements a Power-on Reset module to ensure correct power-up initialization, as well as four low voltage detectors
to monitor the VDD_HV_A and the VDD_LV voltage while device is supplied:
• POR monitors VDD_HV_A during the power-up phase to ensure device is maintained in a safe reset state
• LVDHV3 monitors VDD_HV_A to ensure device is reset below minimum functional supply
• LVDHV5 monitors VDD_HV_A when application uses device in the 5.0 V±10% range
• LVDLVCOR monitors power dom ain No. 1 (PD1)
• LVDLVBKP monitors power domain No. 0 (PD0). VDD_LV is same as PD0 supply.

4.11 Electromagnetic compatibility (EMC) characteristics
Susceptibility tests are performed on a sample basis during product characterization.
4.11.1 Designing hardened software to avoid noise problems
EMC characterization and optimization are performed at component level with a typical application environment and simplified
MCU software. It should be noted that good EMC performance is highly dependent on the user application and the software in
particular.
Therefore it is recommended that the user apply EMC software optimization and pre-qualification tests in relation with the EMC
level requested for the application.
• Software recommendations The software flowchart must include the management of runaway conditions such as:
— Corrupted program counter
— Unexpected reset
— Critical data corruption (control registers)
• Pre-qualification trials Most of the common failures (unexpected reset and program counter corruption) can be
reproduced by manually forcing a low state on the reset pin or the oscillator pins for 1 second.
To complete these trials, ESD stress can be applied directly on the device. When unexpected behavior is detected, the
software can be hardened to prevent unrecoverable errors occurring.

Figure 15. ADC_0 characteristic and error definitions
4.17.1.1 Input impedance and ADC accuracy
T o preserve the accuracy of the A/D converter, it is necessary that analog input pins have low AC impedance. Placing a capacitor
with good high frequency characteristics at the input pin of the device, can be effective: the capacitor shoul d be as large as
possible, ideally infinite. This capacitor contributes to attenuating the noise present on the input pin; furthermore, it sources
charge during the sampling phase, when the analog signal source is a high-impedance source. A real filter, can typically be
obtained by using a series resistance with a capacitor on the in put pin (simple RC Filter). The RC filtering may be limited
according to the value of source impedance of the transducer or circuit supplying the analog signal to be measured. The filter
at the input pins must be designed taking into account the dynamic characteristics of the input signal (bandwidth) and the
equivalent input impedance of the ADC itself.
In fact a current sink contributor is represented by the char ge sharing ef fects with the sampling capacitance: being CS and Cp2
substantially two switched capacitances, with a frequency equal to the conversion rate of the ADC, it can be seen as a resistive

path to ground. For instance, assuming a conversion rate of 1MHz, with CS+Cp2 equal to 3pF , a resistance of 330K is obtained
(Reqiv = 1 / (fc*(CS+Cp2)), where fc represents the conversion rate at the considered channel). To minimize the error induced
by the voltage partitioning between this resistance (sampled voltage on CS+Cp2) and the sum of RS + RF, the external circuit
must be designed to respect the following relation
Eqn. 4
The formula above provides a constraint for external network design, in particular on resist ive path.
Figure 16. Input equivalent circuit
A second aspect involving the capacitance network shall be considered. Assuming the three capacitances CF, CP1 and CP2
initially charged at the source voltage VA (refer to the equivalent circuit reported in Figure 16): when the sampling phase is
started (A/D switch close), a charge sharing phenomena is installed.

In particular two different transient periods can be distinguished:
• A first and quick char ge transfer from the internal capacitance CP1 and CP2 to the sampling capacitance CS occurs (CS
is supposed initially completely discharged):considering a worst case (since the time constant in reality would be
faster) in which CP2 is reported in parallel to CP1 (call CP = CP1 + CP2), the two capacitances CP and CS are in series,
and the time constant is
Eqn. 5
This relation can again be simplified considering CS as an additional worst condition. In reality, transient is faster , but the A/D
converter circuitry has been designed to be robust also in very worst case : the sampling time T s is always much longer than the
internal time co nst a n t .
Eqn. 6
The charge of CP1 and CP2 is redistributed on CS,determining a new value of the voltage VA1 on the capacitance according to
the following equation
Eqn. 7
• A second charge transfer involves also CF (that is typically bigger than the on-chip capacitance) through the resistance
RL: again considering the worst case in which CP2 and CS were in parallel to CP1 (since the time constant in reality
would be faster), the time constant is:
Eqn. 8
In this case, the time constant depends on the external circuit: in particular imposing that the transient is completed well before
the end of sampling time TS, a constraints on RL sizing is obtained:
Eqn. 9
Of course, RL shall be sized also according to the current limitation constraints, in combination with RS (sourc e imp edance)
and RF (filter resistance). Being CF definitively bigger than CP1, CP2 and CS, then the final voltage VA2 (at the end of the char ge
transfer transient) will be much higher than VA1. The following equation must be respected (charge balance assuming now CS
already charged at VA1):
Eqn. 10
The two transients above are not influenced by the voltage source that, due to the presence of the RFCF filter, is not able to
provide the extra charge to compensate the voltage drop on CS with respect to the ideal source VA; the time constant RFCF of
the filter is very high with respect to the sampling time (TS). The filter is typically designed to act as anti-aliasing

Figure 18. Spectral representation of input signal
Calling f0 the bandwidth of the source signal (and as a consequence the cut-off frequency of the anti-aliasing filter, fF),
according to the Nyquist theorem the conversion rate fC must be at least 2f0; it means that the constant time of the filter is greater
than or at least equal to twice the conversion period (TC). Again the conversion period TC is longer than the sampling time TS,
which is just a portion of it, even when fixed channel continuous conversion mode is sel ected (fastest conversion rate at a
specific channel): in conclusion it is evident that the time constant of the filter RFCF is definitively much higher than the
sampling time TS, so the charge level on CS cannot be modified by the analog signal source during the time in which the
sampling switch is closed.
The considerations above lead to impose new constraints on the external circuit, to reduce the accuracy error due to the voltage
drop on CS; from the two charge balance equations above, it is simple to derive Equation 11 between the ideal and real sampled
voltage on CS:
Eqn. 11
From this formula, in the worst case (when VA is maximum, that is for instance 5 V), assuming to accept a maximum error of
half a count, a constraint is evident on CF value:

4.18 Fast Ethernet Controller
MII signals use CMOS signal levels compatible with devices operating at 3.3 V. Signals are not TTL compatible. They follow
the CMOS electrical characteristics.
4.18.1 MII Receive Signal Timing (RXD[3:0], RX_DV, RX_ER, and RX_CLK)
The receiver functions correctly up to a RX_CLK maximum frequency of 25 MHz +1%. There is no minimum frequency
requirement. In addition, the system clock frequency must exceed four times the RX_CLK frequency in 2:1 mode and two times
the RX_CLK frequency in 1:1 mode.
Figure 20. MII receive si gna l timing diagram
4.18.2 MII Transmit Signal Timing (TXD[3:0], TX_EN, TX_ER, TX_CLK)
The transmitter functions correctly up to a TX_CLK maximum frequency of 25 MHz +1%. There is no minimum frequency
requirement. In addition, the system clock frequency must exceed four times the TX_CLK frequency in 2:1 mode and two times
the TX_CLK frequency in 1:1 mode.
The transmit outputs (TXD[3:0], TX_EN, TX_ER) can be programmed to transition from either the ri sing or falling edge of
TX_CLK, and the timing is the same in either case. This options allo ws the use of non-compliant MII PHYs.
Refer to the Fast Ethernet Controller (FEC) chapter of the MPC5646C Reference Manual for details of this option and how to
enable it.
