The e300c2 core does not contain a floating point unit (FPU). The MPC8323E also includes a 32-bit PCI controller, four DMA channels, a security engine, and a 32-bit DDR1/DDR2 memory controller. A new communications complex based on QUICC Engine technology forms the heart of the networking capability of the MPC8323E. The QUICC Engine block contains several peripheral controllers and a 32-bit RISC controller. Protocol support is provided by the main workhorses of the device—the unified communication controllers (UCCs). Note that the MPC8321 and MPC8321E do not support UTOPIA.

The MPC8323E is currently targeted to these specifications. Some of these specifications are independent of the I/O cell, but are included for a more complete reference. These are not purely I/O buffer design specifications. 2.1 Overall DC Electrical Characteristics This section covers the ratings, conditions, and other characteristics. 2.1.1 Absolute Maximum Ratings Table 1 provides the absolute maximum ratings.

Functional and tested operating conditions are given in Table 2. Absolute maximum ratings are stress ratings only, and functional operation at the maximums is not guaranteed. Stresses beyond those listed may affect device reliability or cause permanent damage to the device. 2. Caution: MVIN must not exceed GVDD by more than 0.3 V. This limit may be exceeded for a maximum of 100 ms during power-on reset and power-down sequences. 3. Caution: OVIN must not exceed OVDD by more than 0.3 V. This limit may be exceeded for a maximum of 100 ms during power-on reset and power-down sequences.

GVDD, OVDD, AVDD, and VDD must track each other and must vary in the same direction—either in the positive or negative direction. 2. Minimum temperature is specified with TA; maximum temperature is specified with TJ. 3. All IO pins should be interfaced with peripherals operating at same voltage level. 4. This voltage is the input to the filter discussed in Section 24.2, “PLL Power Supply Filtering” and not necessarily the voltage at the AVDD pin, which may be reduced due to voltage drop across the filter.

The external clock generator should be able to drive 10 pF. 2.2 Power Sequencing The device does not require the core supply voltage (VDD) and IO supply voltages (GVDD and OVDD) to be applied in any particular order. Note that during power ramp-up, before the power supplies are stable and if the I/O voltages are supplied before the core voltage, there might be a period of time that all input and output pins are actively driven and cause contention and excessive current. 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 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 3. Once both the power supplies (I/O voltage and core voltage) are stable, wait for a minimum of 32 clock cycles before negating PORESET. Note that there is no specific power down sequence requirement for the device. I/O voltage supplies (GVDD and OVDD) do not have any ordering requirements with respect to one another.

The values do not include I/O supply power (OVDD and GVDD) or AV DD. For I/O power values, see Table 6. 2. Typical power is based on a nominal voltage of VDD = 1.0 V, ambient temperature, and the core running a Dhrystone benchmark application. The measurements were taken on the MPC8323MDS evaluation board using WC process silicon. 3.

NOTE AVDDn (1.0 V) is estimated to consume 0.05 W (under normal operating conditions and ambient temperature). 4 Clock Input Timing This section provides the clock input DC and AC electrical characteristics for the MPC8323E. NOTE The rise/fall time on QUICC Engine input pins should not exceed 5 ns. This should be enforced especially on clock signals.

Caution: The system, core, security, and QUICC Engine block 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. 5 RESET Initialization This section describes the AC electrical specifications for the reset initialization timing requirements of the MPC8323E.

When the MPC8323E is 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 MPC8323E PowerQUICC II Pro Integrated Communications Processor Reference Manual for more details. 2. tCLKIN is the clock period of the input clock applied to CLKIN. It is only valid when the MPC8323E is in PCI host mode. See the MPC8323E PowerQUICC II Pro Integrated Communications Processor Reference Manual for more details. 3.

Dn_GVDD is expected to be within 50 mV of the DRAM Dn_GVDD at all times. 2. MVREF nREF is expected to be equal to 0.5 × Dn_GVDD, and to track Dn_GVDD DC variations as measured at the receiver.

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 following equation: tDISKEW = ±(T/4 – abs(tCISKEW)) where T is the clock period and abs(tCISKEW) is the absolute value of tCISKEW.

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. ADDR/CMD includes all DDR SDRAM output signals except MCK/MCK, MCS, and MDQ/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. 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. This 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 2 parameters have been set to the same adjustment value. See the MPC8323E PowerQUICC II Pro Integrated Communications Processor Reference Manual for a description and understanding of 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), or data mask (MDM). The data strobe should be centered inside of 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.

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 14). Time-of-flight delays must be added for trace lengths, vias, and connectors in the system. 2. 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. 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. Note that, in general, the clock reference symbol representation is based on three letters representing the clock of a particular functional. 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.

MPC8323E Clock Subsystem The primary clock source for the MPC8323E can be one of two inputs, CLKIN or PCI_CLK, depending on whether the device is configured in PCI host or PCI agent mode, respectively. MPC8323E PowerQUICC II Pro Integrated Communications Processor Family Hardware Specifications, Rev. 4 64 Freescale Semiconductor Clocking 22.1 Clocking in PCI Host Mode When the MPC8323E is configured as a PCI host device (RCWH[PCIHOST] = 1), CLKIN is its primary input clock. CLKIN feeds the PCI clock divider (÷2) and the PCI_SYNC_OUT and PCI_CLK_OUT multiplexors. The CFG_CLKIN_DIV configuration input selects whether CLKIN or CLKIN/2 is driven out on the PCI_SYNC_OUT signal. 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. 22.1.1 PCI Clock Outputs (PCI_CLK_OUT[0:2]) When the MPC8323E is configured as a PCI host, it provides three separate clock output signals, PCI_CLK_OUT[0:2], for external PCI agents. When the device comes out of reset, the PCI clock outputs are disabled and are actively driven to a steady low state. Each of the individual clock outputs can be enabled (enable toggling of the clock) by setting its corresponding OCCR[PCICOEn] bit. All output clocks are phase-aligned to each other. 22.2 Clocking in PCI Agent Mode When the MPC8323E is configured as a PCI agent device, PCI_CLK is the primary input clock. In agent mode, the CLKIN signal should be tied to GND, and the clock output signals, PCI_CLK_OUTn and PCI_SYNC_OUT, are not used. 22.3 System Clock Domains As shown in Figure 43, the primary clock input (frequency) is multiplied up by the system phase-locked loop (PLL) and the clock unit to create three major clock domains: • The coherent system bus clock (csb_clk) • The QUICC Engine clock (ce_clk) • The internal clock for the DDR controller (ddr_clk) • The internal clock for the local bus controller (lb_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 e300c2 core. A second PLL inside the core multiplies up the csb_clk frequency to create the internal clock for the 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 “Reset Configuration” section in the MPC8323E PowerQUICC II Pro Communications Processor Reference Manual for more information. MPC8323E PowerQUICC II Pro Integrated Communications Processor Family Hardware Specifications, Rev. 4 Freescale Semiconductor 65 Clocking The ce_clk frequency is determined by the QUICC Engine PLL multiplication factor (RCWL[CEPMF) and the QUICC Engine PLL division factor (RCWL[CEPDF]) according to the following equation: When CLKIN is the primary input clock, ce_clk = (primary clock input × CEPMF) ÷ (1 + CEPDF) When PCI_CLK is the primary input clock, ce_clk = [primary clock input × CEPMF × (1 + ~CFG_CLKIN_DIV)] ÷ (1 + CEPDF) See the “QUICC Engine PLL Multiplication Factor” section and the “QUICC Engine PLL Division Factor” section in the MPC8323E PowerQUICC II Pro Communications Processor Reference Manual for more information. The DDR SDRAM memory controller operates with a frequency equal to twice the frequency of csb_clk. Note that 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 local bus memory controller operates with a frequency equal to the frequency of csb_clk. Note that lbc_clk is not the external local bus frequency; lbc_clk passes through the LBC clock divider to create the external local bus clock outputs (LSYNC_OUT and LCLK[0:2]). The LBC clock divider ratio is controlled by LCRR[CLKDIV]. See the “LBC Bus Clock and Clock Ratios” section in the MPC8323E PowerQUICC II Pro Communications Processor Reference Manual for more information. In addition, some of the internal units may be required to be shut off or operate at lower frequency than the csb_clk frequency. These units have a default clock ratio that can be configured by a memory mapped register after the device comes out of reset. Table 56 specifies which units have a configurable clock frequency. Refer to the “System Clock Control Register (SCCR)” section in the MPC8323E PowerQUICC II Pro Communications Processor Reference Manual for a detailed description. Table 56. Configurable Clock Units Unit Default Frequency Options Security core, I2C, SAP, TPR csb_clk Off, csb_clk/2, csb_clk/3 PCI and DMA complex csb_clk Off, csb_clk NOTE Setting the clock ratio of these units must be performed prior to any access to them.

Table 58 shows the multiplication factor encodings for the system PLL. NOTE System PLL VCO frequency = 2 × (CSB frequency) × (System PLL VCO divider). The VCO divider needs to be set properly so that the System PLL VCO frequency is in the range of 300–600 MHz. Table 58.

The first domain contain the CSB PLL and the core PLL. The core PLL is connected serially to the CSB PLL, and has the csb_clk as its input clock. The second clock domain has the QUICC Engine PLL. The clock domains are independent, and each of their PLLs are configured separately. Both of the domains has one common input clock.

When Greek letters are not available, the thermal characterization parameter is written as Psi-JT. 23.2 Thermal Management Information For the following sections, PD = (VDD × IDD) + PI/O, where PI/O is the power dissipation of the I/O drivers. 23.2.1 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. As a general statement, 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. 23.2.2 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 MPC8323E PowerQUICC II Pro Integrated Communications Processor Family Hardware Specifications, Rev. 4 72 Freescale Semiconductor 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 = TB + (RθJB × PD) where: TJ = junction temperature (°C) TB = board temperature at the package perimeter (°C) RθJB = junction-to-board thermal resistance (°C/W) per JESD51-8 PD = power dissipation in 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. 23.2.3 Experimental Determination of Junction Temperature To determine the junction temperature of the device in the application after prototypes are available, the thermal characterization parameter (ΨJT) can be used to determine the junction temperature with a measurement of the temperature at the top center of the package case using the following equation: TJ = TT + (ΨJT × PD) where: TJ = junction temperature (°C) TT = thermocouple temperature on top of package (°C) ΨJT = thermal characterization parameter (°C/W) PD = power dissipation in package (W) The thermal characterization parameter is measured per JESD51-2 specification using a 40 gauge type T thermocouple epoxied to the top center of the package case. The thermocouple should be positioned so that the thermocouple junction rests on the package. A small amount of epoxy is placed over the thermocouple junction and over about 1 mm of wire extending from the junction. The thermocouple wire is placed flat against the package case to avoid measurement errors caused by cooling effects of the thermocouple wire. 23.2.4 Heat Sinks and Junction-to-Case Thermal Resistance In some application environments, a heat sink is required 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 MPC8323E PowerQUICC II Pro Integrated Communications Processor Family Hardware Specifications, Rev. 4 Freescale Semiconductor 73 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. To illustrate the thermal performance of the devices with heat sinks, the thermal performance 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.

The best method is to use 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 which would lift the edge of the package or peel the package from the board. Such peeling forces reduce the solder joint lifetime of the package. Recommended maximum force on the top of the package is 10 lb (4.5 kg) force. If an adhesive attachment is planned, the adhesive should be intended for attachment to painted or plastic surfaces and its performance verified under the application requirements. 23.3.1 Experimental Determination of the Junction Temperature with a Heat Sink When heat sink is used, the junction temperature is determined from a thermocouple inserted at the interface between the case of the package and the interface material. A clearance slot or hole is normally required in the heat sink. Minimizing the size of the clearance is important to minimize the change in thermal performance caused by removing part of the thermal interface to the heat sink. Because of the experimental difficulties with this technique, many engineers measure the heat sink temperature and then back calculate the case temperature using a separate measurement of the thermal resistance of the MPC8323E PowerQUICC II Pro Integrated Communications Processor Family Hardware Specifications, Rev. 4 Freescale Semiconductor 75 System Design Information interface. From this case temperature, the junction temperature is determined from the junction-to-case thermal resistance. TJ = TC + (RθJC × PD) where: TC = case temperature of the package (°C) RθJC = junction-to-case thermal resistance (°C/W) PD = power dissipation (W) 24 System Design Information This section provides electrical and thermal design recommendations for successful application of the MPC8323E. 24.1 System Clocking The MPC8323E includes three PLLs. • The system PLL (AVDD2) generates the system clock from the externally supplied CLKIN input. The frequency ratio between the system and CLKIN is selected using the system PLL ratio configuration bits as described in Section 22.4, “System PLL Configuration.” • The e300 core PLL (AVDD3) generates the core clock as a slave to the system clock. The frequency ratio between the e300 core clock and the system clock is selected using the e300 PLL ratio configuration bits as described in Section 22.5, “Core PLL Configuration.” • The QUICC Engine PLL (AVDD1) which uses the same reference as the system PLL. The QUICC Engine block generates or uses external sources for all required serial interface clocks. 24.2 PLL Power Supply Filtering Each of the PLLs listed above is provided with power through independent power supply pins. The voltage level at each AVDDn pin should always be equivalent to VDD, and preferably these voltages are derived directly from VDD through a low frequency filter scheme such as the following. There are a number of ways to reliably provide power to the PLLs, but the recommended solution is to provide five independent filter circuits as illustrated in Figure 44, one to each of the five AVDD pins. By providing independent filters to each PLL the opportunity to cause noise injection from one PLL to the other is reduced. This circuit is intended to filter noise in the PLLs resonant frequency range from a 500 kHz to 10 MHz range. 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. MPC8323E PowerQUICC II Pro Integrated Communications Processor Family Hardware Specifications, Rev. 4 76 Freescale Semiconductor System Design Information Each circuit should be placed as close as possible to the specific AVDD pin being supplied to minimize noise coupled from nearby circuits. 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 44 shows the PLL power supply filter circuit.
