Power Sequencing
This section details the power sequencing considerations for the MPC8349EA.
2.2.1
Power-Up Sequencing
MPC8349EA does not require the core supply voltage (VDD and AVDD) and I/O supply voltages (GVDD,
LVDD, and OVDD) to be applied in any particular order. During the power ramp up, before the power

Power Characteristics
supplies are stable and if the I/O voltages are supplied before the core voltage, there may be a period of
time that all input and output pins will actively be driven and cause contention and excessive current from
3A to 5A. In order to avoid actively driving the I/O pins and to eliminate excessive current draw, apply the
core voltage (VDD) before the I/O voltage (GVDD, LVDD, and OVDD) and assert PORESET before the
power supplies fully ramp up. In the case where the core voltage is applied first, the core voltage supply
must rise to 90% of its nominal value before the I/O supplies reach 0.7 V, see Figure 4.

Typical power is based on a voltage of VDD = 1.2 V, a junction temperature of TJ = 105°C, and a Dhrystone benchmark
application.
Thermal solutions may need to design to a value higher than typical power based on the end application, TA target, and I/O
power.
Maximum power is based on a voltage of VDD = 1.2 V, worst case process, a junction temperature of TJ = 105°C, and an
artificial smoke test.
Typical power is based on a voltage of VDD = 1.3 V, a junction temperature of TJ = 105°C, and a Dhrystone benchmark

Notes:
1. Caution: The system, core, USB, security, and TSEC must not exceed their respective maximum or minimum operating
frequencies.
2. Rise and fall times for CLKIN/PCI_CLK are measured at 0.4 and 2.7 V.
3. Timing is guaranteed by design and characterization.
4. This represents the total input jitter—short term and long term—and is guaranteed by design.
5. The CLKIN/PCI_CLK driver’s closed loop jitter bandwidth should be < 500 kHz at –20 dB. The bandwidth must be set low to
allow cascade-connected PLL-based devices to track CLKIN drivers with the specified jitter.
6. Spread spectrum clocking is allowed with 1% input frequency down-spread at maximum 50 KHz modulation rate regardless
of input frequency.

DDR and DDR2 SDRAM
This section describes the DC and AC electrical specifications for the DDR SDRAM interface of the
MPC8349EA. Note that DDR SDRAM is GVDD(typ) = 2.5 V and DDR2 SDRAM is GVDD(typ) = 1.8 V.
The AC electrical specifications are the same for DDR and DRR2 SDRAM.

Notes:
1. tCISKEW represents the total amount of skew consumed by the controller between MDQS[n] and any corresponding bit that
will be captured with MDQS[n]. This should be subtracted from the total timing budget.
2. The amount of skew that can be tolerated from MDQS to a corresponding MDQ signal is called tDISKEW. This can be
determined by the equation: tDISKEW = ± (T/4 – abs (tCISKEW)); where T is the clock period and abs (tCISKEW) is the absolute
value of tCISKEW.
3. This specification applies only to the DDR interface.

Notes:
1. The symbols for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state)(reference)(state) for inputs
and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. Output hold time can be read as DDR timing (DD) from
the rising or falling edge of the reference clock (KH or KL) until the output goes invalid (AX or DX). For example, tDDKHAS
symbolizes DDR timing (DD) for the time tMCK memory clock reference (K) goes from the high (H) state until outputs (A) are
set up (S) or output valid time. Also, tDDKLDX symbolizes DDR timing (DD) for the time tMCK memory clock reference (K) goes
low (L) until data outputs (D) are invalid (X) or data output hold time.
2. All MCK/MCK referenced measurements are made from the crossing of the two signals ±0.1 V.
3. ADDR/CMD includes all DDR SDRAM output signals except MCK/MCK, MCS, and MDQ/MECC/MDM/MDQS. For the
ADDR/CMD setup and hold specifications, it is assumed that the clock control register is set to adjust the memory clocks by
1/2 applied cycle.
4. tDDKHMH follows the symbol conventions described in note 1. For example, tDDKHMH describes the DDR timing (DD) from the
rising edge of the MCK(n) clock (KH) until the MDQS signal is valid (MH). tDDKHMH can be modified through control of the
DQSS override bits in the TIMING_CFG_2 register and is typically set to the same delay as the clock adjust in the CLK_CNTL
register. The timing parameters listed in the table assume that these two parameters are set to the same adjustment value.
See the MPC8349EA PowerQUICC II Pro Integrated Host Processor Family Reference Manual for the timing modifications
enabled by use of these bits.
5. Determined by maximum possible skew between a data strobe (MDQS) and any corresponding bit of data (MDQ), ECC
(MECC), or data mask (MDM). The data strobe should be centered inside the data eye at the pins of the microprocessor.
6. All outputs are referenced to the rising edge of MCK(n) at the pins of the microprocessor. Note that tDDKHMP follows the
symbol conventions described in note 1.
Figure 6 shows the DDR SDRAM output timing for the MCK to MDQS skew measurement (tDDKHMH).

t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tGTKHDV symbolizes GMII transmit timing (GT)
with respect to the tGTX clock reference (K) going to the high state (H) relative to the time date input signals (D) reaching the
valid state (V) to state or setup time. Also, tGTKHDX symbolizes GMII transmit timing (GT) with respect to the tGTX clock

the clock reference symbol is based on three letters representing the clock of a particular function. For example, the subscript

Notes:
1. In general, the clock reference symbol for this section is based on the symbols RGT to represent RGMII and RTBI timing. For
example, the subscript of tRGT represents the TBI (T) receive (RX) clock. Also, the notation for rise (R) and fall (F) times
follows the clock symbol. For symbols representing skews, the subscript is SK followed by the clock being skewed (RGT).
2. This implies that PC board design requires clocks to be routed so that an additional trace delay of greater than 1.5 ns is added
to the associated clock signal.
3. For 10 and 100 Mbps, tRGT scales to 400 ns ± 40 ns and 40 ns ± 4 ns, respectively.
4. Duty cycle may be stretched/shrunk during speed changes or while transitioning to a received packet clock domains as long
as the minimum duty cycle is not violated and stretching occurs for no more than three tRGT of the lowest speed transitioned.
5. Duty cycle reference is LVDD/2.

Notes:
1. The symbols for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state)(reference)(state) for inputs
and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tMDKHDX symbolizes management data
timing (MD) for the time tMDC from clock reference (K) high (H) until data outputs (D) are invalid (X) or data hold time. Also,
tMDDVKH symbolizes management data timing (MD) with respect to the time data input signals (D) reach the valid state (V)
relative to the tMDC clock reference (K) going to the high (H) state or setup time. For rise and fall times, the latter convention
is used with the appropriate letter: R (rise) or F (fall).
2. This parameter is dependent on the csb_clk speed (that is, for a csb_clk of 267 MHz, the maximum frequency is 8.3 MHz
and the minimum frequency is 1.2 MHz; for a csb_clk of 375 MHz, the maximum frequency is 11.7 MHz and the minimum
frequency is 1.7 MHz).
3. This parameter is dependent on the csb_clk speed (that is, for a csb_clk of 267 MHz, the delay is 70 ns and for a csb_clk of
333 MHz, the delay is 58 ns).

1. The symbols for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state)(reference)(state) for inputs
and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tUSIXKH symbolizes USB timing (US) for
the input (I) to go invalid (X) with respect to the time the USB clock reference (K) goes high (H). Also, tUSKHOX symbolizes
USB timing (US) for the USB clock reference (K) to go high (H), with respect to the output (O) going invalid (X) or output hold
time.
2. All timings are in reference to USB clock.
3. All signals are measured from OVDD/2 of the rising edge of the USB clock to 0.4 × OVDD of the signal in question for 3.3 V
signaling levels.
4. Input timings are measured at the pin.
5. For active/float timing measurements, the Hi-Z or off-state is defined to be when the total current delivered through the
component pin is less than or equal to that of the leakage current specification.

Notes:
1. All outputs are measured from the midpoint voltage of the falling/rising edge of tTCLK to the midpoint of the signal in question.
The output timings are measured at the pins. All output timings assume a purely resistive 50 Ω load (see Figure 18).
Time-of-flight delays must be added for trace lengths, vias, and connectors in the system.
2. The symbols for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state)(reference)(state) for inputs
and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tJTDVKH symbolizes JTAG device timing
(JT) with respect to the time data input signals (D) reaching the valid state (V) relative to the tJTG clock reference (K) going
to the high (H) state or setup time. Also, tJTDXKH symbolizes JTAG timing (JT) with respect to the time data input signals (D)
went invalid (X) relative to the tJTG clock reference (K) going to the high (H) state. In general, the clock reference symbol is
based on three letters representing the clock of a particular function. For rise and fall times, the latter convention is used with
the appropriate letter: R (rise) or F (fall).
3. TRST is an asynchronous level sensitive signal. The setup time is for test purposes only.
4. Non-JTAG signal input timing with respect to tTCLK.
5. Non-JTAG signal output timing with respect to tTCLK.
6. Guaranteed by design and characterization.

Notes:
1. The symbols for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state)(reference)(state) for inputs
and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tI2DVKH symbolizes I2C timing (I2) with
respect to the time data input signals (D) reach the valid state (V) relative to the tI2C clock reference (K) going to the high (H)
state or setup time. Also, tI2SXKL symbolizes I2C timing (I2) for the time that the data with respect to the start condition (S)
goes invalid (X) relative to the tI2C clock reference (K) going to the low (L) state or hold time. Also, tI2PVKH symbolizes I2C
timing (I2) for the time that the data with respect to the stop condition (P) reaches the valid state (V) relative to the tI2C clock
reference (K) going to the high (H) state or setup time. For rise and fall times, the latter convention is used with the appropriate
letter: R (rise) or F (fall).
2. The device provides a hold time of at least 300 ns for the SDA signal (referred to the VIH(min) of the SCL signal) to bridge
the undefined region of the falling edge of SCL.
3. The maximum tI2DVKH must be met only if the device does not stretch the LOW period (tI2CL) of the SCL signal.
4. CB = capacitance of one bus line in pF.
5.)The device does not follow the “I2C-BUS Specifications” version 2.1 regarding the tI2CF AC parameter.

Notes:
1. PCI timing depends on M66EN and the ratio between PCI1/PCI2. Refer to the PCI chapter of the reference manual for a
description of M66EN.
2. The symbols for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state)(reference)(state) for inputs
and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tPCIVKH symbolizes PCI timing (PC) with
respect to the time the input signals (I) reach the valid state (V) relative to the PCI_SYNC_IN clock, tSYS, reference (K) going
to the high (H) state or setup time. Also, tPCRHFV symbolizes PCI timing (PC) with respect to the time hard reset (R) went
high (H) relative to the frame signal (F) going to the valid (V) state.
3. See the timing measurement conditions in the PCI 2.3 Local Bus Specifications.
4. For active/float timing measurements, the Hi-Z or off-state is defined to be when the total current delivered through the
component pin is less than or equal to the leakage current specification.
5. Input timings are measured at the pin.
6. The setup and hold time is with respect to the rising edge of PORESET.

Notes:
1. This pin is an open-drain signal. A weak pull-up resistor (1 kΩ) should be placed on this pin to OVDD.
2. This pin is an open-drain signal. A weak pull-up resistor (2–10 kΩ) should be placed on this pin to OVDD.
3. During reset, this output is actively driven rather than three-stated.
4. These JTAG pins have weak internal pull-up P-FETs that are always enabled.
5. This pin should have a weak pull-up if the chip is in PCI host mode. Follow the PCI specifications.
6. This pin must always be tied to GND.
7. This pin must always be left not connected.
8. Thermal sensitive resistor.
9. It is recommended that MDIC0 be tied to GND using an 18.2 Ω resistor and MDIC1 be tied to DDR power using an 18.2 Ω
resistor.
10.TSEC1_TXD[3] is required an external pull-up resistor. For proper functionality of the device, this pin must be pulled up or
actively driven high during a hard reset. No external pull-down resistors are allowed to be attached to this net.
11. A weak pull-up resistor (2–10 kΩ) should be placed on this pin to LVDD1.
12. For systems that boot from local bus (GPCM)-controlled NOR flash, a pullup on LGPL4 is required.

Figure 41. MPC8349EA Clock Subsystem
The primary clock source can be one of two inputs, CLKIN or PCI_CLK, depending on whether the device
is configured in PCI host or PCI agent mode. When the MPC8349EA is configured as a PCI host device,
CLKIN is its primary input clock. CLKIN feeds the PCI clock divider (÷2) and the multiplexors for
PCI_SYNC_OUT and PCI_CLK_OUT. The CFG_CLKIN_DIV configuration input selects whether
CLKIN or CLKIN/2 is driven out on the PCI_SYNC_OUT signal. The OCCR[PCICDn] parameters select
whether CLKIN or CLKIN/2 is driven out on the PCI_CLK_OUTn signals.
PCI_SYNC_OUT is connected externally to PCI_SYNC_IN to allow the internal clock subsystem to
synchronize to the system PCI clocks. PCI_SYNC_OUT must be connected properly to PCI_SYNC_IN,
with equal delay to all PCI agent devices in the system, to allow the MPC8349EA to function. When the
device is configured as a PCI agent device, PCI_CLK is the primary input clock and the CLKIN signal
should be tied to GND.

Freescale Semiconductor
Clocking
As shown in Figure 41, the primary clock input (frequency) is multiplied up by the system phase-locked
loop (PLL) and the clock unit to create the coherent system bus clock (csb_clk), the internal clock for the
DDR controller (ddr_clk), and the internal clock for the local bus interface unit (lbiu_clk).
The csb_clk frequency is derived from a complex set of factors that can be simplified into the following
equation:
csb_clk = {PCI_SYNC_IN × (1 + CFG_CLKIN_DIV)} × SPMF
In PCI host mode, PCI_SYNC_IN × (1 + CFG_CLKIN_DIV) is the CLKIN frequency.
The csb_clk serves as the clock input to the e300 core. A second PLL inside the e300 core multiplies the
csb_clk frequency to create the internal clock for the e300 core (core_clk). The system and core PLL
multipliers are selected by the SPMF and COREPLL fields in the reset configuration word low (RCWL),
which is loaded at power-on reset or by one of the hard-coded reset options. See the chapter on reset,
clocking, and initialization in the MPC8349EA Reference Manual for more information on the clock
subsystem.
The internal ddr_clk frequency is determined by the following equation:
ddr_clk = csb_clk × (1 + RCWL[DDRCM])
ddr_clk is not the external memory bus frequency; ddr_clk passes through the DDR clock divider (÷2) to
create the differential DDR memory bus clock outputs (MCK and MCK). However, the data rate is the
same frequency as ddr_clk.
The internal lbiu_clk frequency is determined by the following equation:
lbiu_clk = csb_clk × (1 + RCWL[LBIUCM])
lbiu_clk is not the external local bus frequency; lbiu_clk passes through the LBIU clock divider to create
the external local bus clock outputs (LSYNC_OUT and LCLK[0:2]). The LBIU clock divider ratio is
controlled by LCCR[CLKDIV].
In addition, some of the internal units may have to be shut off or operate at lower frequency than the
csb_clk frequency. Those units have a default clock ratio that can be configured by a memory-mapped
register after the device exits reset. Table 56 specifies which units have a configurable clock frequency.

The DDR data rate is 2x the DDR memory bus frequency.
3 The DDR data rate is 2x the DDR memory bus frequency.
4 The local bus frequency is 1/2, 1/4, or 1/8 of the lbiu_clk frequency (depending on LCCR[CLKDIV]) which is in turn 1x or 2x the
csb_clk frequency (depending on RCWL[LBIUCM]).
All frequency combinations shown in the table below may not be available. Maximum operating
frequencies depend on the part ordered, see Section 22.1, “Part Numbers Fully Addressed by This

As described in Section 19, “Clocking,” the LBIUCM, DDRCM, and SPMF parameters in the reset
configuration word low and the CFG_CLKIN_DIV configuration input signal select the ratio between the
primary clock input (CLKIN or PCI_CLK) and the internal coherent system bus clock (csb_clk). Table 59
and Table 60 show the expected frequency values for the CSB frequency for select csb_clk to
CLKIN/PCI_SYNC_IN ratios.

Notes:
1. Junction temperature is a function of die size, 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.
2. Per SEMI G38-87 and JEDEC JESD51-2 with the single-layer board horizontal.
3. Per JEDEC JESD51-6 with the board horizontal, 1 m/s is approximately equal to 200 linear feet per minute (LFM).
4. Thermal resistance between the die and the printed-circuit board per JEDEC JESD51-8. Board temperature is measured on
the top surface of the board near the package.
5. Thermal resistance between the die and the case top surface as measured by the cold plate method (MIL SPEC-883 Method
1012.1).
6. Thermal characterization parameter indicating the temperature difference between package top and the junction temperature
per JEDEC JESD51-2. When Greek letters are not available, the thermal characterization parameter is written as Psi-JT.
20.2
Thermal Management Information
For the following sections, PD = (VDD × IDD) + PI/O where PI/O is the power dissipation of the I/O drivers.
See Table 5 for I/O power dissipation values.
20.2.1
Estimation of Junction Temperature with Junction-to-Ambient
Thermal Resistance
An estimation of the chip junction temperature, TJ, can be obtained from the equation:
TJ = TA + (RθJA × PD)
where:
TJ = junction temperature (°C)
TA = ambient temperature for the package (°C)
RθJA = junction-to-ambient thermal resistance (°C/W)
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. Generally, the value obtained on a single-layer board is appropriate for
a 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. Test cases have
demonstrated that errors of a factor of two (in the quantity TJ – TA) are possible.
20.2.2
Estimation of Junction Temperature with Junction-to-Board
Thermal Resistance
The thermal performance of a device cannot be adequately predicted from the junction-to-ambient thermal
resistance. The thermal performance of any component is strongly dependent on the power dissipation of
surrounding components. In addition, the ambient temperature varies widely within the application. For
many natural convection and especially closed box applications, the board temperature at the perimeter
MPC8349EA PowerQUICC II Pro Integrated Host Processor Hardware Specifications, Rev. 13
Freescale Semiconductor
75
Thermal
(edge) of the package is approximately the same as the local air temperature near the device. Specifying
the local ambient conditions explicitly as the board temperature provides a more precise description of the
local ambient conditions that determine the temperature of the device.
At a known board temperature, the junction temperature is estimated using the following equation:
TJ = TA + (RθJA × PD)
where:
TJ = junction temperature (°C)
TA = ambient temperature for the package (°C)
RθJA = junction-to-ambient thermal resistance (°C/W)
PD = power dissipation in the package (W)
When the heat loss from the package case to the air can be ignored, acceptable predictions of junction
temperature can be made. The application board should be similar to the thermal test condition: the
component is soldered to a board with internal planes.
20.2.3
Experimental Determination of Junction Temperature
To determine the junction temperature of the device in the application after prototypes are available, use
the thermal characterization parameter (ΨJT) to determine the junction temperature and a measure of the
temperature at the top center of the package case using the following equation:
TJ = TT + (ΨJT × PD)
where:
TJ = junction temperature (°C)
TT = thermocouple temperature on top of package (°C)
ΨJT = junction-to-ambient thermal resistance (°C/W)
PD = power dissipation in the package (W)
The thermal characterization parameter is measured per the 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 junction. The thermocouple wire
is placed flat against the package case to avoid measurement errors caused by cooling effects of the
thermocouple wire.
20.2.4
Heat Sinks and Junction-to-Case Thermal Resistance
Some application environments require a heat sink to provide the necessary thermal management of the
device. 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
MPC8349EA PowerQUICC II Pro Integrated Host Processor Hardware Specifications, Rev. 13
76
Freescale Semiconductor
Thermal
where:
RθJA = junction-to-ambient thermal resistance (°C/W)
RθJC = junction-to-case thermal resistance (°C/W)
RθCA = 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 instance, the user 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.
The thermal performance of devices with heat sinks has been simulated with a few commercially available
heat sinks. The heat sink choice is determined by the application environment (temperature, air flow,
adjacent component power dissipation) and the physical space available. Because there is not a standard
application environment, a standard heat sink is not required.

Accurate thermal design requires thermal modeling of the application environment using computational
fluid dynamics software which can model both the conduction cooling and the convection cooling of the
air moving through the application. Simplified thermal models of the packages can be assembled using the
junction-to-case and junction-to-board thermal resistances listed in the thermal resistance table. More
detailed thermal models can be made available on request.

Heat Sink Attachment
When heat sinks are attached, an interface material is required, preferably thermal grease and a spring clip.
The spring clip should connect to the printed-circuit board, either to the board itself, to hooks soldered to
the board, or to a plastic stiffener. Avoid attachment forces that can lift the edge of the package or peel the
package from the board. Such peeling forces reduce the solder joint lifetime of the package. The
recommended maximum force on the top of the package is 10 lb force (4.5 kg force). Any adhesive
attachment should attach to painted or plastic surfaces, and its performance should be verified under the
application requirements.
20.3.1
Experimental Determination of the Junction Temperature with a
Heat Sink
When a 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. Minimize the size of the clearance 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.
TJ = TC + (RθJC × PD)
where:
TJ = junction temperature (°C)
TC = case temperature of the package (°C)
RθJC = junction-to-case thermal resistance (°C/W)
PD = power dissipation (W)
21 System Design Information
This section provides electrical and thermal design recommendations for successful application of the
MPC8349EA.
21.1
System Clocking
The MPC8349EA includes two PLLs:
1. The platform PLL generates the platform clock from the externally supplied CLKIN input. The
frequency ratio between the platform and CLKIN is selected using the platform PLL ratio
configuration bits as described in Section 19.1, “System PLL Configuration.”
MPC8349EA PowerQUICC II Pro Integrated Host Processor Hardware Specifications, Rev. 13
Freescale Semiconductor

System Design Information
2. The e300 core PLL generates the core clock as a slave to the platform clock. The frequency ratio
between the e300 core clock and the platform clock is selected using the e300 PLL ratio
configuration bits as described in Section 19.2, “Core PLL Configuration.”
21.2
PLL Power Supply Filtering
Each PLL gets power through independent power supply pins (AVDD1, AVDD2, respectively). The AVDD
level should always equal to VDD, and preferably these voltages are derived directly from VDD through a
low frequency filter scheme.
There are a number of ways to provide power reliably to the PLLs, but the recommended solution is to
provide four independent filter circuits as illustrated in Figure 42, one to each of the four AVDD pins.
Independent filters to each PLL reduce the opportunity to cause noise injection from one PLL to the other.
The circuit filters noise in the PLL resonant frequency range from 500 kHz to 10 MHz. It should be built
with surface mount capacitors with minimum effective series inductance (ESL). Consistent with the
recommendations of Dr. Howard Johnson in High Speed Digital Design: A Handbook of Black Magic
(Prentice Hall, 1993), multiple small capacitors of equal value are recommended over a single large value
capacitor.
To minimize noise coupled from nearby circuits, each circuit should be placed as closely as possible to the
specific AVDD pin being supplied. It should be possible to route directly from the capacitors to the AVDD
pin, which is on the periphery of package, without the inductance of vias.
Figure 42 shows the PLL power supply filter circuit.

Decoupling Recommendations
Due to large address and data buses and high operating frequencies, the MPC8349EA can generate
transient power surges and high frequency noise in its power supply, especially while driving large
capacitive loads. This noise must be prevented from reaching other components in the MPC8349EA
system, and the device itself requires a clean, tightly regulated source of power. Therefore, the system
designer should place at least one decoupling capacitor at each VDD, OVDD, GVDD, and LVDD pin of the
device. These capacitors should receive their power from separate VDD, OVDD, GVDD, LVDD, and GND
power planes in the PCB, with short traces to minimize inductance. Capacitors can be placed directly under
the device using a standard escape pattern. Others can surround the part.
These capacitors should have a value of 0.01 or 0.1 µF. Only ceramic SMT (surface mount technology)
capacitors should be used to minimize lead inductance, preferably 0402 or 0603 sizes.
In addition, distribute several bulk storage capacitors around the PCB, feeding the VDD, OVDD, GVDD,
and LVDD planes, to enable quick recharging of the smaller chip capacitors. These bulk capacitors should
MPC8349EA PowerQUICC II Pro Integrated Host Processor Hardware Specifications, Rev. 13
80
Freescale Semiconductor
System Design Information
have a low ESR (equivalent series resistance) rating to ensure the quick response time. They should also
be connected to the power and ground planes through two vias to minimize inductance. Suggested bulk
capacitors are 100–330 µF (AVX TPS tantalum or Sanyo OSCON).
21.4
Connection Recommendations
To ensure reliable operation, connect unused inputs to an appropriate signal level. Unused active low
inputs should be tied to OVDD, GVDD, or LVDD as required. Unused active high inputs should be
connected to GND. All NC (no-connect) signals must remain unconnected.
Power and ground connections must be made to all external VDD, GVDD, LVDD, OVDD, and GND pins of
the MPC8349EA.
21.5
Output Buffer DC Impedance
The MPC8349EA drivers are characterized over process, voltage, and temperature. For all buses, the
driver is a push-pull single-ended driver type (open drain for I2C).
To measure Z0 for the single-ended drivers, an external resistor is connected from the chip pad to OVDD
or GND. Then the value of each resistor is varied until the pad voltage is OVDD/2 (see Figure 43). The
output impedance is the average of two components, the resistances of the pull-up and pull-down devices.
When data is held high, SW1 is closed (SW2 is open) and RP is trimmed until the voltage at the pad equals
OVDD/2. RP then becomes the resistance of the pull-up devices. RP and RN are designed to be close to each
other in value. Then, Z0 = (RP + RN) ÷ 2.

Figure 43. Driver Impedance Measurement
Two measurements give the value of this resistance and the strength of the driver current source. First, the
output voltage is measured while driving logic 1 without an external differential termination resistor. The
measured voltage is V1 = Rsource × Isource. Second, the output voltage is measured while driving logic 1
with an external precision differential termination resistor of value Rterm. The measured voltage is
MPC8349EA PowerQUICC II Pro Integrated Host Processor Hardware Specifications, Rev. 13
Freescale Semiconductor
81
Ordering Information
V2 = (1 ÷ (1/R1 + 1/R2)) × Isource. Solving for the output impedance gives Rsource = Rterm × (V1 ÷ V2 – 1).
The drive current is then Isource = V1 ÷ Rsource.
Table 65 summarizes the signal impedance targets. The driver impedance are targeted at minimum VDD,
nominal OVDD, 105°C.

21.6
Configuration Pin Multiplexing
The MPC8349EA power-on configuration options can be set through external pull-up or pull-down
resistors of 4.7 kΩ on certain output pins (see the customer-visible configuration pins). These pins are used
as output only pins in normal operation.
However, while HRESET is asserted, these pins are treated as inputs, and the value on these pins is latched
when PORESET deasserts. Then the input receiver is disabled and the I/O circuit takes on its normal
function. Careful board layout with stubless connections to these pull-up/pull-down resistors coupled with
the large value of the pull-up/pull-down resistor should minimize the disruption of signal quality or speed
for the output pins.
21.7
Pull-Up Resistor Requirements
The MPC8349EA requires high resistance pull-up resistors (10 kΩ is recommended) on open-drain pins,
including I2C pins, and IPIC interrupt pins.
For more information on required pull-up resistors and the connections required for the JTAG interface,
refer to application note AN2931, “PowerQUICC Design Checklist.”
