Power Sequencing
MPC8349E does not require the core supply voltage and I/O supply voltages to be applied in any particular
order. Note that during the power ramp up, before the power supplies are stable, there may be a period of
time that I/O pins are actively driven. After the power is stable, as long as PORESET is asserted, most I/O
pins are three-stated. To minimize the time that I/O pins are actively driven, it is recommended to apply
core voltage before I/O voltage and assert PORESET before the power supplies fully ramp up.

The values do not include I/O supply power (OVDD, LVDD, GVDD) or AVDD. For I/O power values, see Table 5.
Typical power is based on a voltage of VDD = 1.2 V, a junction temperature of T J = 105°C, and a Dhrystone benchmark
application.
3 Thermal solutions may need to design to a value higher than typical power based on the end application, T target, and I/O

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.

Notes:
1. tPCI_SYNC_IN is the clock period of the input clock applied to PCI_SYNC_IN. In PCI host mode, the primary clock is applied
to the CLKIN input, and PCI_SYNC_IN period depends on the value of CFG_CLKIN_DIV. See the MPC8349E
PowerQUICC™ II Pro Integrated Host Processor Family Reference Manual.
2. tCLKIN is the clock period of the input clock applied to CLKIN. It is valid only in PCI host mode. See the MPC8349E
PowerQUICC™ II Pro Integrated Host Processor Family Reference Manual.
3. POR configuration signals consist of CFG_RESET_SOURCE[0:2] and CFG_CLKIN_DIV.

Notes:
1. DLL lock times are a function of the ratio between the output clock and the coherency system bus clock (csb_clk). A 2:1 ratio
results in the minimum and an 8:1 ratio results in the maximum.
2. The csb_clk is determined by the CLKIN and system PLL ratio. See Section 19, “Clocking.”

noise on MV REF may not exceed ±2% of the DC value.
3. VTT is not applied directly to the device. It is the supply to which far end signal termination is made and is expected to be
equal to MVREF. This rail should track variations in the DC level of MVREF.

Notes:
1. The symbols used 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 went 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 setup (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. In the source synchronous mode, MCK/MCK can be shifted in 1/4 applied cycle increments through the clock control register.
For the skew measurements referenced for tAOSKEW it is assumed that the clock adjustment is set to align the
address/command valid with the rising edge of MCK.
4. 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.
5. Note that 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. In source synchronous mode, this will typically be set to the same
delay as the clock adjust in the CLK_CNTL register. The timing parameters listed in the table assume that these 2 parameters
have been set to the same adjustment value. See the MPC8349E PowerQUICC™ II Pro Integrated Host Processor Family
Reference Manual, for a description and understanding of the timing modifications enabled by use of these bits.
6. 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 of the data eye at the pins of the MPC8349E.
7. All outputs are referenced to the rising edge of MCK(n) at the pins of the MPC8349E. Note that tDDKHMP follows the symbol
conventions described in note 1.

Table 16 provides approximate delay information that can be expected for the address and command
signals of the DDR controller for various loadings, which can be useful for a system utilizing the DLL.
These numbers are the result of simulations for one topology. The delay numbers will strongly depend on
the topology used. These delay numbers show the total delay for the address and command to arrive at the
DRAM devices. The actual delay could be different than the delays seen in simulation, depending on the
system topology. If a heavily loaded system is used, the DLL loop may need to be adjusted to meet setup
requirements at the DRAM.

Three-Speed Ethernet Controller (TSEC)—
GMII/MII/TBI/RGMII/RTBI Electrical Characteristics
The electrical characteristics specified here apply to the gigabit media independent interface (GMII), the
media independent interface (MII), ten-bit interface (TBI), reduced gigabit media independent
interface (RGMII), and reduced ten-bit interface (RTBI) signals except management data input/output
(MDIO) and management data clock (MDC). The MII, GMII, and TBI interfaces are defined for 3.3 V,
and the RGMII and RTBI interfaces can operate at 3.3 or 2.5 V. The RGMII and RTBI interfaces follow
the Hewlett-Packard Reduced Pin-Count Interface for Gigabit Ethernet Physical Layer Device
Specification, Version 1.2a (9/22/2000). The electrical characteristics for MDIO and MDC are specified
in Section 8.3, “Ethernet Management Interface Electrical Characteristics.”
8.1.1
TSEC DC Electrical Characteristics
All GMII, MII, TBI, RGMII, and RTBI drivers and receivers comply with the DC parametric attributes
specified in Table 19 and Table 20. The potential applied to the input of a GMII, MII, TBI, RGMII, or
RTBI receiver may exceed the potential of the receiver power supply (that is, a RGMII driver powered
from a 3.6-V supply driving VOH into a RGMII receiver powered from a 2.5-V supply). Tolerance for
dissimilar RGMII driver and receiver supply potentials is implicit in these specifications. The RGMII and
RTBI signals are based on a 2.5-V CMOS interface voltage as defined by JEDEC EIA/JESD8-5.

Notes:
1. The symbols for timing specifications follow the pattern 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, 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
reference (K) going to the high state (H) relative to the time date input signals (D) going invalid (X) or hold time. In general,
the clock reference symbol is based on three letters representing the clock of a particular function. For example, the subscript
of tGTX represents the GMII(G) transmit (TX) clock. For rise and fall times, the latter convention is used with the appropriate
letter: R (rise) or F (fall).
2. This symbol represents the external GTX_CLK125 signal and does not follow the original symbol naming convention.

(GR) with respect to the time data input signals (D) reaching the valid state (V) relative to the tRX clock reference (K) going
to the high state (H) or setup time. Also, tGRDXKL symbolizes GMII receive timing (GR) with respect to the time data input
signals (D) went invalid (X) relative to the tGRX clock reference (K) going to the low (L) state or hold time. In general, the clock
reference symbol is based on three letters representing the clock of a particular function. For example, the subscript of t GRX
represents the GMII (G) receive (RX) clock. For rise and fall times, the latter convention is used with the appropriate letter:

and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tMTKHDX symbolizes MII transmit timing
(MT) for the time tMTX clock reference (K) going high (H) until data outputs (D) are invalid (X). In general, the clock reference
symbol is based on two to three letters representing the clock of a particular function. For example, the subscript of t MTX
represents the MII(M) transmit (TX) clock. For rise and fall times, the latter convention is used with the appropriate letter:
R (rise) or F (fall).

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, tTTKHDV symbolizes the TBI transmit

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, tTRDVKH symbolizes TBI receive timing
(TR) with respect to the time data input signals (D) reach the valid state (V) relative to the tTRX clock reference (K) going to
the high (H) state or setup time. Also, tTRDXKH symbolizes TBI receive timing (TR) with respect to the time data input signals
(D) went invalid (X) relative to the tTRX 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 example, the subscript of tTRX represents the TBI
(T) receive (RX) clock. For rise and fall times, the latter convention is used with the appropriate letter: R (rise) or F (fall). For
symbols representing skews, the subscript SK followed by the clock that is being skewed (TRX).
2. Setup and hold time of even numbered RCG are measured from the riding edge of PMA_RX_CLK1. Setup and hold times
of odd-numbered RCG are measured from the riding edge of PMA_RX_CLK0.

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.
6. This symbol represents the external GTX_CLK125 and does not follow the original symbol naming convention.

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).

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, tLBIXKH1 symbolizes local bus timing (LB)
for the input (I) to go invalid (X) with respect to the time the tLBK clock reference (K) goes high (H), in this case for clock one
(1). Also, tLBKHOX symbolizes local bus timing (LB) for the tLBK 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 the rising edge of LSYNC_IN.
3. All signals are measured from OVDD/2 of the rising edge of LSYNC_IN to 0.4 × OVDD of the signal in question for 3.3 V
signaling levels.
4. Input timings are measured at the pin.
5. tLBOTOT1 should be used when RCWH[LALE] is not set and when the load on the LALE output pin is at least 10 pF less than
the load on the LAD output pins.
6. tLBOTOT2 should be used when RCWH[LALE] is set and when the load on the LALE output pin is at least 10 pF less than the
load on the LAD output pins.
7. tLBOTOT3 should be used when RCWH[LALE] is set and when the load on the LALE output pin equals the load on the LAD
output pins.
8. 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. 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, tLBIXKH1 symbolizes local bus timing (LB)
for the input (I) to go invalid (X) with respect to the time the tLBK clock reference (K) goes high (H), in this case for clock one
(1). Also, tLBKHOX symbolizes local bus timing (LB) for the tLBK 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 the falling edge of LCLK0 (for all outputs and for LGTA and LUPWAIT inputs) or the rising edge
of LCLK0 (for all other inputs).
3. All signals are measured from OVDD/2 of the rising/falling edge of LCLK0 to 0.4 × OVDD of the signal in question for 3.3 V
signaling levels.
4. Input timings are measured at the pin.
5. tLBOTOT1 should be used when RCWH[LALE] is not set and when the load on the LALE output pin is at least 10 pF less than
the load on the LAD output pins.
6. tLBOTOT2 should be used when RCWH[LALE] is set and when the load on the LALE output pin is at least 10 pF less than the
load on the LAD output pins.the
7. tLBOTOT3 should be used when RCWH[LALE] is set and when the load on the LALE output pin equals to the load on the LAD
output pins.
8. For purposes of 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.
9. DLL bypass mode is not recommended for use at frequencies above 66 MHz.

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 25).
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. MPC8349E 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.

Notes:
1. PCI timing depends on M66EN and the ratio between PCI1/PCI2. Refer to the PCI chapter of the reference manual for a

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 2.2 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.

Table 46. GPIO Input AC Timing Specifications1
Characteristic
GPIO inputs—minimum pulse width
Notes:
1. Input specifications are measured from the 50 percent level of the signal to the 50 percent level of the rising edge of CLKIN.
Timings are measured at the pin.
2. GPIO inputs and outputs are asynchronous to any visible clock. GPIO outputs should be synchronized before use by external
synchronous logic. GPIO inputs must be valid for at least tPIWID ns to ensure proper operation.

Notes:
1. Output specifications are measured from the 50 percent level of the rising edge of CLKIN to the 50 percent level of the signal.
Timings are measured at the pin.
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, tNIKHOX symbolizes the internal timing
(NI) for the time SPICLK clock reference (K) goes to the high state (H) until outputs (O) are invalid (X).

Figure 39. MPC8349E 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 MPC8349E 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 MPC8349E to function. When the
MPC8349E is configured as a PCI agent device, PCI_CLK is the primary input clock and the CLKIN
signal should be tied to GND.

Clocking
As shown in Figure 39, 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 MPC8349E 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 52 specifies which units have a configurable clock frequency.

The CLKIN frequency, RCWL[SPMF], and RCWL[COREPLL] settings must be chosen so that the resulting csb_clk, MCK,
LCLK[0:2], and core_clk frequencies do not exceed their respective maximum or minimum operating frequencies. The value
of SCCR[ENCCM], SCCR[USBDRCM]and SCCR[USBMPHCM] must be programmed so that the maximum internal operating
frequency of the security core and USB modules does not exceed the respective values listed in this table.
2 The DDR data rate is 2x the DDR memory bus frequency.
3 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]).

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)
MPC8349E PowerQUICC™ II Pro Integrated Host Processor Hardware Specifications, Rev. 10
Freescale Semiconductor
73
Thermal
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
(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)
MPC8349E PowerQUICC™ II Pro Integrated Host Processor Hardware Specifications, Rev. 10
74
Freescale Semiconductor
Thermal
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
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.

System Design Information
21 System Design Information
This section provides electrical and thermal design recommendations for successful application of the
MPC8349E.
21.1
System Clocking
The MPC8349E includes two PLLs:
1. The platform PLL (AVDD1) 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.”
2. The e300 core PLL (AVDD2) 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 V DD 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 five independent filter circuits as illustrated in Figure 40, one to each of the five 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 40 shows the PLL power supply filter circuit.

21.3
Decoupling Recommendations
Due to large address and data buses and high operating frequencies, the MPC8349E 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 MPC8349E system, and the
MPC8349E 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
MPC8349E. 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 V DD, OVDD, GVDD,
and LVDD planes, to enable quick recharging of the smaller chip capacitors. These bulk capacitors should
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 MPC8349E.
21.5
Output Buffer DC Impedance
The MPC8349E 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 41). 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 41. 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
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.

Configuration Pin Multiplexing
The MPC8349E 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 MPC8349E requires high resistance pull-up resistors (10 kΩ is recommended) on open-drain pins,
including I2C pins, the Ethernet Management MDIO pin, and IPIC interrupt pins.
