The MPC852T has a 1.8-V core and a 3.3-V I/O operation with 5-V TTL compatibility. The MPC852T integrated communications controller is a versatile one-chip integrated microprocessor and peripheral combination that can be used in a variety of controller applications. It particularly excels in Ethernet control applications, including CPE equipment, Ethernet routers and hubs, VoIP clients, and WiFi access points.

Functional operating conditions are provided with the DC electrical specifications in Table 5. Absolute maximum ratings are stress ratings only; functional operation at the maxima is not guaranteed. Stresses beyond those listed may affect device reliability or cause permanent damage to the device. Caution: All inputs that tolerate 5 V cannot be more than 2.5 V greater than V DDH. This restriction applies to power-up and normal operation (that is, if the MPC852T is unpowered, a voltage greater than 2.5 V must not be applied to its inputs).

This device contains circuitry protecting against damage that high-static voltage or electrical fields cause; however, Freescale recommends taking normal precautions to avoid application of any voltages higher than maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate logic voltage level (for example, either GND or VDD). 4 Thermal Characteristics Table 3 shows the thermal characteristics for the MPC852T.

NOTE The VDDSYN power dissipation is negligible. 7.1 Estimation with Junction-to-Ambient Thermal Resistance An estimation of the chip junction temperature, TJ, in °C can be obtained from the equation: TJ = TA +(RθJA × PD) MPC852T PowerQUICC™ Hardware Specifications, Rev. 4 Freescale Semiconductor 9 Thermal Calculation and Measurement where: TA = ambient temperature (ºC) RθJA = package junction-to-ambient thermal resistance (ºC/W) PD = power dissipation in package The junction-to-ambient thermal resistance is an industry standard value that provides a quick and easy estimation of thermal performance. However, the answer is only an estimate; test cases have demonstrated that errors of a factor of two (in the quantity TJ – TA) are possible. 7.2 Estimation with Junction-to-Case Thermal Resistance Historically, the thermal resistance has frequently been 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 (ºC/W) RθJC = junction-to-case thermal resistance (ºC/W) RθCA = case-to-ambient thermal resistance (ºC/W) RθJC is device-related and cannot be influenced by the user. The user adjusts the thermal environment to affect the case-to-ambient thermal resistance, RθCA. For instance, the user can change the airflow around the device, add a heat sink, change the mounting arrangement on the printed-circuit board, or change the thermal dissipation on the printed-circuit board surrounding the device. This thermal model is most useful for ceramic packages with heat sinks where some 90% of the heat flows through the case and the heat sink to the ambient environment. For most packages, a better model is required. 7.3 Estimation with Junction-to-Board Thermal Resistance A simple package thermal model that has demonstrated reasonable accuracy (about 20%) is a two-resistor model consisting of a junction-to-board and a junction-to-case thermal resistance. The junction-to-case covers the situation where a heat sink is used or where a substantial amount of heat is dissipated from the top of the package. The junction-to-board thermal resistance describes the thermal performance when most of the heat is conducted to the printed-circuit board. Thermal performance of most plastic packages and especially PBGA packages is strongly dependent on the board temperature. If the board temperature is known, an estimate of the junction temperature in the environment can be made using the following equation: TJ = TB +(RθJB × PD) where: RθJB = junction-to-board thermal resistance (ºC/W) TB = board temperature (ºC) PD = power dissipation in package MPC852T PowerQUICC™ Hardware Specifications, Rev. 4 10 Freescale Semiconductor References If the board temperature is known and the heat loss from the package case to the air can be ignored, acceptable predictions of junction temperature can be made. For this method to work, the board and board mounting must be similar to the test board used to determine the junction-to-board thermal resistance, namely a 2s2p (board with a power and a ground plane) and vias attaching the thermal balls to the ground plane. 7.4 Estimation Using Simulation When the board temperature is not known, a thermal simulation of the application is needed. The simple two-resistor model can be used with the thermal simulation of the application [2], or a more accurate and complex model of the package can be used in the thermal simulation. 7.5 Experimental Determination 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: ΨJT = thermal characterization parameter TT = thermocouple temperature on top of package PD = power dissipation in package The thermal characterization parameter is measured per JESD51-2 specification published by JEDEC 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 that cooling effects of the thermocouple wire cause. 8 References Semiconductor Equipment and Materials International (415) 964-5111 805 East Middlefield Rd Mountain View, CA 94043 MIL-SPEC and EIA/JESD (JEDEC) specifications 800-854-7179 or (Available from Global Engineering documents) 303-397-7956 JEDEC Specifications http://www.jedec.org 1.

MPC852T PowerQUICC™ Hardware Specifications, Rev. 4 Freescale Semiconductor 11 Power Supply and Power Sequencing 9 Power Supply and Power Sequencing This section provides design considerations for the MPC852T power supply. The MPC852T has a core voltage (VDDL) and PLL voltage (VDDSYN) that operates at a lower voltage than the I/O voltage VDDH. The I/O section of the MPC852T is supplied with 3.3 V across VDDH and VSS (GND). The signals PA[0:3], PA[8:11], PB15, PB[24:25]; PB[28:31], PC[4:7], PC[12:13], PC15] PD[3:15], TDI, TDO, TCK, TRST, TMS, MII_TXEN, MII_MDIO are 5-V tolerant. All inputs cannot be more than 2.5 V greater than VDDH. In addition, 5-V tolerant pins can not exceed 5.5 V, and the remaining input pins cannot exceed 3.465 V. This restriction applies to power-on reset or power down and normal operation. One consequence of multiple power supplies is that when power is initially applied, the voltage rails ramp up at different rates. The rates depend on the nature of the power supply, the type of load on each power supply, and the manner in which different voltages are derived. The following restrictions apply: • VDDL must not exceed VDDH during power-on reset or power down. • VDDL must not exceed 1.9 V, and VDDH must not exceed 3.465. These cautions are necessary for the long-term reliability of the part. If they are violated, the electrostatic discharge (ESD) protection diodes are forward-biased, and excessive current can flow through these diodes. If the system power supply design does not control the voltage sequencing, the circuit shown in Figure 3 can be added to meet these requirements. The MUR420 Schottky diodes control the maximum potential difference between the external bus and core power supplies on power-on reset, and the 1N5820 diodes regulate the maximum potential difference on power-down. VDDH VDDL MUR420 1N5820 Figure 3. Example Voltage Sequencing Circuit 10 Mandatory Reset Configurations The MPC852T requires a mandatory configuration during reset. If hardware reset configuration word (HRCW) is enabled, by asserting the RSTCONF during HRESET assertion, the HRCW[DBGC] value that is needed to be set to binary X1 in the hardware reset configuration word (HRCW) and the SIUMCR[DBGC] should be programmed with the same value in the boot code after reset. If hardware reset configuration word (HRCW) is disabled, by negating the RSTCONF during the HRESET assertion, the SIUMCR[DBGC] should be programmed with binary X1 in the boot code after reset. MPC852T PowerQUICC™ Hardware Specifications, Rev. 4 12 Freescale Semiconductor Layout Practices The MBMR[GPLB4DIS], PAPAR, PADIR, PBPAR, PBDIR, PCPAR, and PCDIR should be configured with the mandatory value in Table 6 in the boot code after the reset deasserts.

Each GND pin should likewise be provided with a low-impedance path to ground. The power supply pins drive distinct groups of logic on chip. The VDD power supply should be bypassed to ground using at least four 0.1 µF bypass capacitors located as close as possible to the four sides of the package. Each board designed should be characterized and additional appropriate decoupling capacitors should be used if required. The capacitor leads and associated printed-circuit traces connecting to chip VDD and GND should be kept to less than half an inch per capacitor lead. At a minimum, a four-layer board employing two inner layers as VDD and GND planes should be used. All output pins on the MPC852T have fast rise and fall times. Printed-circuit (PC) trace interconnection length should be minimized to minimize undershoot and reflections that these fast output switching times cause. This recommendation particularly applies to the address and data buses. Maximum PC trace lengths of six inches are recommended. Capacitance calculations should consider all device loads as well as parasitic capacitances that the PC traces cause. Attention to proper PCB layout and bypassing becomes especially critical in systems with higher capacitive loads, because these loads create higher transient currents in the VDD and GND circuits. Pull up all unused inputs or signals that are inputs during reset. Special care should be taken to minimize the noise levels on the PLL supply pins.

The timing for BG input is relevant when the MPC852T is selected to work with external bus arbiter. 4 For part speeds above 50MHz, use 2ns for B17. 5 The D(0:31) and DP(0:3) input timings B18 and B19 refer to the rising edge of the CLKOUT in which the TA input signal is asserted. 6 For part speeds above 50MHz, use 2ns for B19. 7 The D(0:31) and DP(0:3) input timings B20 and B21 refer to the falling edge of the CLKOUT. This timing is valid only for read accesses controlled by chip-selects under control of the UPM in the memory controller, for data beats where DLT3 = 1 in the UPM RAM words. (This is only the case where data is latched on the falling edge of CLKOUT.) 8 This formula applies to bus operation up to 50 MHz. 9 The timing B30 refers to CS when ACS = 00 and to WE(0:3) when CSNT = 0. 10 The signal UPWAIT is considered asynchronous to the CLKOUT and synchronized internally. The timings specified in B37 and B38 are specified to enable the freeze of the UPM output signals as described in Figure 19. 11 The AS signal is considered asynchronous to the CLKOUT. The timing B39 is specified in order to allow the behavior specified in Figure 22.
