During the power ramp up, before the power MPC8349EA PowerQUICC II Pro Integrated Host Processor Hardware Specifications, Rev. 13 Freescale Semiconductor 9 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. Voltage I/O Voltage (GVDD, LVDD, OVDD) Core Voltage (VDD, AVDD) 0.7 V 90% Time Figure 4. Power Sequencing Example I/O voltage supplies (GVDD, LVDD, and OVDD) do not have any ordering requirements with respect to one another. 3 Power Characteristics The estimated typical power dissipation for the MPC8349EA device is shown in Table 4.

MPC8349EA PowerQUICC II Pro Integrated Host Processor Hardware Specifications, Rev. 13 10 Freescale Semiconductor Power Characteristics 2 3 4 5 6 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 application. Maximum power is based on a voltage of VDD = 1.3 V, worst case process, a junction temperature of TJ = 105°C, and an artificial smoke test.

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.

Parameter MDQS epilogue end Symbol 1 Min Max Unit Notes tDDKHME –0.6 0.6 ns 6 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).

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 timing (TT) with respect to the time from tTTX (K) going high (H) until the referenced data signals (D) reach the valid state (V) or setup time. Also, tTTKHDX symbolizes the TBI transmit timing (TT) with respect to the time from tTTX (K) going high (H) until the referenced data signals (D) reach the invalid state (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 tTTX represents the TBI (T) transmit (TX) clock. For rise and fall times, the latter convention is used with the appropriate letter: R (rise) or F (fall).

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.

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.

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.

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.

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. MPC8349EA PowerQUICC II Pro Integrated Host Processor Hardware Specifications, Rev. 13 66 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. Table 56.

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 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.

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 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. Table 64 shows heat sink thermal resistance for TBGA of the MPC8349EA. Table 64.

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 79 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. 10 Ω VDD AVDD (or L2AVDD) 2.2 µF 2.2 µF GND Low ESL Surface Mount Capacitors Figure 42. PLL Power Supply Filter Circuit 21.3 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. OVDD RN SW2 Data Pad SW1 RP OGND 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. Table 65.

See Table 1, Tj = 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.” 22 Ordering Information This section presents ordering information for the device discussed in this document, and it shows an example of how the parts are marked.
