DLLIN Synchronizes the internal clocks with an external device. Note: When the DLL is disabled, pull this pin low (GND). 1.3 Reset and Configuration Signals Table 1-4. Signal Name Type Reset and Configuration Signals Signal Description PORESET Input Power-On Reset When asserted, this line causes the MSC8102 to enter power-on reset state. RSTCONF Input Reset Configuration1 Used during reset configuration sequence of the chip. A detailed explanation of its function is provided in the MSC8102 Reference Manual. This signal is sampled upon deassertion of PORESET. HRESET Input/ Output Hard Reset When asserted as an input, this signal causes the MSC8102 to enter the hard reset state. When the device is in a hard reset state, it drives the signal as an open-drain output. SRESET Input/ Output Soft Reset When asserted as an input, this signal causes the MSC8102 to enter the soft reset state. When the device is in a soft reset state, it drives the signal as an open-drain output. Note: When PORESET is deasserted, the MSC8102 also samples the following signals: • BM[0–2]—Selects the boot mode. • MODCK[1–2]—Selects the clock configuration. • SWTE—Enables the software watchdog timer. • DSISYNC, DSI64, CNFGS, and CHIP_ID[0–3]—Configures the DSI. Refer to Table 1-5 for details on these signals. MSC8102 Quad Core Digital Signal Processor, Rev. 12 Freescale Semiconductor 1-3 Signals/Connections 1.4 Direct Slave Interface, System Bus, and Interrupt Signals The direct slave interface (DSI) is combined with the system bus because they share some common signal lines. Individual assignment of a signal to a specific signal line is configured through internal registers. Table 1-5 describes the signals in this group. Note: Although there are fifteen interrupt request (IRQ) connections to the core processors, there are multiple external lines that can connect to these internal signal lines. After reset, the default configuration enables only IRQ[1–7], but includes two input lines each for IRQ[1–3] and IRQ7. The designer must select one line for each required interrupt and reconfigure the other external signal line or lines for alternate functions. Additional alternate IRQ lines and IRQ[8–15] are enabled through the GPIO signal lines. Table 1-5.

Signal Name NMI NMI_OUT PSDVAL Type Description Input Non-Maskable Interrupt When an external device asserts this line, it generates an non-maskable interrupt in the MSC8102, which is processed internally (default) or is directed to an external host for processing (see NMI_OUT). Output Non-Maskable Interrupt Output An open-drain pin driven from the MSC8102 internal interrupt controller. Assertion of this output indicates that a non-maskable interrupt is pending in the MSC8102 internal interrupt controller, waiting to be handled by an external host. Input/Output Port Size Data Valid Indicates that a data beat is valid on the data bus. The difference between the TA pin and the PSDVAL pin is that the TA pin is asserted to indicate data transfer terminations, while the PSDVAL signal is asserted with each data beat movement. When TA is asserted, PSDVAL is always asserted. However, when PSDVAL is asserted, TA is not necessarily asserted. For example, if the DMA initiates a double word (2 × 64 bits) transaction to a memory device with a 32-bit port size, PSDVAL is asserted three times without TA and, finally, both pins are asserted to terminate the transfer.

See the System Interface Unit (SIU) chapter in the MSC8102 Reference Manual for details on how to configure these pins. When used as the bus control arbiter, the MSC8102 can support up to three external bus masters. Each master uses its own set of Bus Request, Bus Grant, and Data Bus Grant signals (BR/BG/DBG, EXT_BR2/EXT_BG2/EXT_DBG2, and EXT_BR3/EXT_BG3/EXT_DBG3). Each of these signal sets must be configured to indicate whether the external master is or is not a MSC8102 master device. See the Bus Configuration Register (BCR) description in the System Interface Unit (SIU) chapter in the MSC8102 Reference Manual for details on how to configure these pins. The second and third set of pins is defined by EXT_xxx to indicate that they can only be used with external master devices. The first set of pins (BR/BG/DBG) have a dual function. When the MSC8102 is not the bus arbiter, these signals (BR/BG/DBG) are used by the MSC8102 to obtain master control of the bus. 1.5 Memory Controller Signals Refer to the Memory Controller chapter in the MSC8102 Reference Manual for details on configuring these signals.

Each internal SC140 core has an EOnce module, but they are all accessed externally by the same two signals EE0 and EE1. The MSC8102 supports the standard set of Test Access Port (TAP) signals defined by IEEE 1149.1 Standard Test Access Port and Boundary-Scan Architecture specification and described in Table 1-8. Table 1-8. Signal Name Type JTAG Test Access Port Signals Signal Description EE0 Input EOnCE Event Bit 0 Used for putting the internal SC140 cores into Debug mode.

For additional information, see the MSC8102 User’s Guide and MSC8102 Reference Manual. 2.1 Maximum Ratings CAUTION This device contains circuitry protecting against damage due to high static voltage or electrical fields; however, normal precautions should be taken to avoid exceeding maximum voltage ratings. Reliability is enhanced if unused inputs are tied to an appropriate logic voltage level (for example, either GND or VDD). In calculating timing requirements, adding a maximum value of one specification to a minimum value of another specification does not yield a reasonable sum. A maximum specification is calculated using a worst case variation of process parameter values in one direction. The minimum specification is calculated using the worst case for the same parameters in the opposite direction. Therefore, a “maximum” value for a specification never occurs in the same device with a “minimum” value for another specification; adding a maximum to a minimum represents a condition that can never exist. Table 2-1 describes the maximum electrical ratings for the MSC8102. Table 2-1.

When designing systems such as DSP farms using the DSI, use a device loading of 4 pF per pin. AC timings are based on a 50 pF load, except where noted otherwise, and a 50 Ω transmission line. For any additional pF, add 0.07 ns for the delay and take the RC delay into consideration. 2.5.1 Output Buffer Impedances Table 2-5.

The impedance may vary by ±25% depending on device process and operating temperature. Start-Up Timing Starting the device requires coordination among several input sequences including clocking, reset, and power. Section 2.5.3 describes the clocking characteristics. Section 2.5.4 describes the reset and power-up characteristics. You must use the following guidelines when starting up an MSC8102 device: • • • PORESET and TRST must be asserted externally for the duration of the power-up sequence. See Table 2-10 for timing. If possible, bring up the VDD and VDDH levels together. For designs with separate power supplies, bring up the VDDH levels and then the VDD levels (see Figure 2-3 and Figure 2-4). CLKIN can start toggling after VDDH reaches its nominal level, but it must toggle before VDD reaches 0.5 V to guarantee correct device operation (see Figure 2-2 and Figure 2-4). The following figures show acceptable start-up sequence examples. Figure 2-2 shows a sequence in which VDD and VDDH are raised together. Figure 2-3 shows a sequence in which CLKIN starts toggling after VDDH reaches its nominal level and before VDD is applied. Figure 2-4 shows a sequence in which VDD is raised after VDDH and CLKIN begins to toggle shortly before VDD reaches the 0.5 V level.

MSC8102 Quad Core Digital Signal Processor, Rev. 12 2-6 Freescale Semiconductor AC Timings 2.5.4 Reset Timing The MSC8102 has several inputs to the reset logic: • Power-on reset (PORESET) • External hard reset (HRESET) • External soft reset (SRESET) • Software watchdog reset • Bus monitor reset • Host reset command through JTAG All MSC8102 reset sources are fed into the reset controller, which takes different actions depending on the source of the reset. The reset status register indicates the most recent sources to cause a reset. Table 2-9 describes the reset sources. Table 2-9. Reset Sources Name Direction Description Power-on reset (PORESET) Input Initiates the power-on reset flow that resets the MSC8102 and configures various attributes of the MSC8102. On PORESET, the entire MSC8102 device is reset. SPLL and DLL states are reset, HRESET and SRESET are driven, the SC140 extended cores are reset, and system configuration is sampled. The clock mode (MODCK bits), reset configuration mode, boot mode, Chip ID, and use of either a DSI 64 bits port or a System Bus 64 bits port are configured only when PORESET is asserted. External Hard reset (HRESET) Input/ Output Initiates the hard reset flow that configures various attributes of the MSC8102. While HRESET is asserted, SRESET is also asserted. HRESET is an open-drain pin. Upon hard reset, HRESET and SRESET are driven, the SC140 extended cores are reset, and system configuration is sampled. The most configurable features are reconfigure. These features are defined in the 32-bit hard reset configuration word described in Hard Reset Configuration Word section of the Reset chapter in the MSC8102 Reference Manual. External Soft reset (SRESET) Input/ Output Initiates the soft reset flow. The MSC8102 detects an external assertion of SRESET only if it occurs while the MSC8102 is not asserting reset. SRESET is an open-drain pin. Upon soft reset, SRESET is driven, the SC140 extended cores are reset, and system configuration is maintained. Software watchdog reset Internal When the MSC8102 watchdog count reaches zero, a software watchdog reset is signalled. The enabled software watchdog event then generates an internal hard reset sequence. Bus monitor reset Internal When the MSC8102 bus monitor count reaches zero, a bus monitor hard reset is asserted. The enabled bus monitor event then generates an internal hard reset sequence. Host reset command through the TAP Internal When a host reset command is written through the Test Access Port (TAP), the TAP logic asserts the soft reset signal and an internal soft reset sequence is generated. MSC8102 Quad Core Digital Signal Processor, Rev. 12 Freescale Semiconductor 2-7 Specifications Table 2-10 summarizes the reset actions that occur as a result of the different reset sources.

PORESET and TRST should be asserted external during power-up. CLKIN may start toggling after VDDH reaches the nominal level, but must start toggling before VDD reaches 0.5 V. 2.5.4.2 Reset Configuration The MSC8102 has two mechanisms for writing the reset configuration: • Through the direct slave interface (DSI), or • Through the system bus When reset configuration written through the system bus, the MSC8102 uses as a configuration master or as a configuration slave. If a configuration slave is selected, but no special configuration word is written, a default configuration word is applied.

The REFCLK is either the DLLIN signal or, if DLL is disabled, the CLKOUT signal. Memory controller signals, however, trigger on four points within a REFCLK cycle. Each cycle is divided by four internal ticks: T1, T2, T3, and T4. T1 always occurs at the rising edge of REFCLK (and T3 at the falling edge), as Figure 2-6 shows. Figure 2-6 is a graphical representation of the internal ticks. REFCLK T1 Figure 2-6.

Values are measured from the 50% level of the REFCLK rising edge to the 50% signal level. The maximum bus frequency depends on the mode: • In 60x-compatible mode connected to another MSC8102 device, the frequency is determined by adding the input and output longest timing values, which results in a frequency of 75 MHz for 30 pF output capacitance. • In single-master mode, the frequency depends on the timing of the devices connected to the MSC8102.

The MSC8102 is available in a 431-pin High Temperature Coefficient for Expansion Flip Chip-Ceramic Ball Grid Array (FC-CBGA (HCTE)). 3.1 FC-CBGA (HCTE) Package Description Figure 3-1 and Figure 3-2 show top and bottom views of the FC-CBGA (HCTE) package, including pinouts. To conform to JDEC requirements, the package is based on a 23 × 23 position (20 × 20 mm) layout with the outside perimeter depopulated. Therefore, ball position numbering starts with B2. Signal names shown in the figures are typically the signal assigned after reset. Signals that are only used during power-on reset (SWTE, DSISYNC, DSI64, MODCK[1–2], CNFGS, and CHIP_ID[0–3]) are not shown in these figures if there is another signal assigned to the pin after reset. Also, there are several signals that are designated as IRQ lines immediately after reset, but represent duplicate IRQ lines that should be reconfigured by the user. To represent these signals uniquely in the figures, the second functions (BADDR[29–31], DP[1–7], and INT_OUT) are used. Table 3-1 lists the MSC8102 signals alphabetically by signal name. Connections with multiple names are listed individually by each name. Signals with programmable polarity are shown both as signals which are asserted low (default) and high (that is, NAME/NAME). Table 3-2 lists the signals numerically by pin number. Each pin number is listed once with the various signals that are multiplexed to it.

In turn VDDH must not exceed VDD/VCCSYN by more than 2.6 V at any time, including during power-on reset. VDD/VCCSYN must not exceed VDDH by more than 0.4 V at any time, including during power-on reset. Use the following guidelines for power-up and power-down sequences: • Assert PORESET before applying power and keep the signal driven low until the power reaches the required minimum power levels. This can be implemented via a weak pull-down resistor. • CLKIN can be held low or allowed to toggle during the beginning of the power-up sequence. However, CLKIN must start toggling before the deassertion of PORESET and after both power supplies have reached nominal voltage levels. • To maintain the proper relationship and power-up sequence between the power levels, the recommendation is to use “bootstrap” diodes between the power rails, as shown in Figure 4-1. 3.3 V (VDDH ) I/O Power MUR420 MUR420 MUR420 Core/PLL Supply Figure 4-1. MUR420 1.6 V (VDD/VCCSYN ) Bootstrap Diodes for Power-Up Sequencing Select the bootstrap diodes such that a nominal VDD/VCCSYN is sourced from the VDDH power supply until the VDD/VCCSYN power supply becomes active. In Figure 4-1, four MUR420 Schottky barrier diodes are connected in series; each has a forward voltage (VF) of 0.6 V at high currents, so these diodes provide a 2.4 V drop, maintaining 0.9 V on the 1.6 V power line. Once the core/PLL power supply stabilizes at 1.6 V, the bootstrap diodes will be reverse biased with negligible leakage current. The VF should be effective at the current levels required by the processor. Do not use diodes with a nominal VF that drops too low at high current. Figure 4-2 shows the recommended power decoupling circuit for the core power supply. The voltage regulator and the decoupling capacitors should supply the required device current without any drop in voltage on the device pins. The voltage on the package pins should not drop below 1.5 V even for a very short spikes. This can be achieved by using the following guidelines: MSC8102 Quad Core Digital Signal Processor, Rev. 12 Freescale Semiconductor 4-1 Design Considerations — For the core supply, use a voltage regulator rated at 1.6 V with nominal rating of at least 3 A. This rating does not reflect actual average current draw, but is recommended because it resists changes imposed by transient spikes and has better voltage recovery time than lower current rated supplies. — Decouple the supply using low-ESR capacitors mounted as close as possible to the socket. Figure 4-2 shows three capacitors in parallel to reduce the resistance. Three capacitors is a recommended minimum number. If possible, mount at least one of the capacitors directly below the MSC8102 device. maximum IR drop of 15 mV at 1 A Lmax = 2 cm 1.6 V Power supply or Voltage Regulator (Imin = 3 A) One 0.01 µF capacitor for every 3 Core supply pads. + - MSC8102 Bulk/Tantalum capacitors with low ESR and ESL Note: Use at least three capacitors. Each capacitor must be at least 150 µF. Figure 4-2. High Freq. capacitors (very low ESR and ESL) Core Power Supply Decoupling Each VCC and VDD pin on the MSC8102 should be provided with a low-impedance path to the board power supply. Similarly, each GND pin should be provided with a low-impedance path to ground. The power supply pins drive distinct groups of logic on the chip. The VCC power supply should be bypassed to ground using at least four 0.1 µF by-pass capacitors located as closely as possible to the four sides of the package. The capacitor leads and associated printed circuit traces connecting to chip VCC, VDD, and GND should be kept to less than half an inch per capacitor lead. A four-layer board is recommended, employing two inner layers as VCC and GND planes. All output pins on the MSC8102 have fast rise and fall times. PCB trace interconnection length should be minimized in order to minimize undershoot and reflections caused by these fast output switching times. This recommendation particularly applies to the address and data busses. Maximum PCB trace lengths of six inches are recommended. For the DSI control signals in Synchronous mode, make sure that the layout supports the DSI AC timing requirements and minimizes any signal crosstalk. Capacitance calculations should consider all device loads as well as parasitic capacitances due to the PCB traces. 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 VCC, VDD, and GND circuits. Pull up all unused inputs or signals that will be inputs during reset. Special care should be taken to minimize the noise levels on the PLL supply pins. There is one pair of PLL supply pins: VCCSYN-GNDSYN. To ensure internal clock stability, filter the power to the VCCSYN input with a circuit similar to the one in Figure 4-3. To filter as much noise as possible, place the circuit as close as possible to VCCSYN. The 0.01µF capacitor should be closest to VCCSYN, followed by the 10-µF capacitor, the 10-nH inductor, and finally the 10-Ω resistor to VDD. These traces should be kept short and direct. Provide an extremely low impedance path to ground MSC8102 Quad Core Digital Signal Processor, Rev. 12 4-2 Freescale Semiconductor Connectivity Guidelines for GNDSYN. Bypass GNDSYN to VCCSYN with a 0.01-µF capacitor as close as possible to the chip package. For best results, place this capacitor on the backside of the PCB aligned with the depopulated void on the MSC8102 located in the square defined by positions, L11, L12, L13, M11, M12, M13, N11, N12, and N13. VCCSYN VDD 10Ω 10nH 10 µF Figure 4-3. 0.01 µF VCCSYN Bypass Note: See the MSC8102 Design Checklist (AN2506) for additional information. 4.2 Connectivity Guidelines Unused output pins can be disconnected, and unused input pins should be connected to their non-active value, except for the following: • If the DSI is unused (bit DDR[DSIDIS] is set), then HCS and HBCS must be tied to VDD and all the rest of the DSI signals can be disconnected. • When the DSI uses Synchronous mode, HTA must be pulled up. In asynchronous mode, HTA should be pulled either up or down depending on design requirements. • HDST can be disconnected if the DSI is in Big-endian mode, or if the DSI is in Little-endian mode and DCR[DSRFA] bit is set. • When the DSI is in 64-bit data bus mode and DCR[BEM] is cleared, HWBS[1–3]/HDBS[1–3]/HWBE[1–3]/HDBE[1–3] and HWBS[4–7]/HDBS[4–7]/HWBE[4–7]/HDBE[4–7]/PWE[4–7]/PSDDQM[4–7]/PBS[4–7] must be tied to VDD. • When the DSI is in 32-bit data bus mode and DCR[BEM] is cleared, HWBS[1–3]/HDBS[1–3]/HWBE[1–3]/HDBE[1–3] must be tied to VDD. • When the DSI is in Asynchronous mode, HBRST and HCLKIN should either be disconnected or tied to VDD. • When using the DSI in Synchronous mode, use special care when laying out the control signals. Test the layout to make sure that it supports the specified DSI AC timing values and minimizes signal cross-coupling. • The following signals can be disconnected in single-master mode (BCR[EBM] is reset): BG, DBG, EXT_BG[2–3], EXT_DBG[2-3], GBL and TS. • The following signals must be pulled up: HRESET, SRESET, ARTRY, TA, TEA, PSDVAL, and AACK. • In single-master mode, ABB and DBB can be selected as IRQ inputs and be connected to the non-active value. In other modes, they must be pulled up. MSC8102 Quad Core Digital Signal Processor, Rev. 12 Freescale Semiconductor 4-3 Design Considerations • In single-master mode with the DLL disabled (that is, the DLLDIS bit in the Hard Reset Configuration Word is set), the following connections should be used: — Connect the oscillator output through a buffer to CLKIN. — Connect DLLIN to GND (pull low). — Connect CLKOUT through a zero-delay buffer to the slave device (for example, SDRAM) using the following guidelines: ° ° ° The maximum delay between the slave and CLKOUT must not exceed 0.7 ns. The maximum load on CLKOUT must not exceed 10 pF. Use a zero-delay buffer with a jitter less than 0.3 ns. • If the 60x-compatible system bus is not used and SIUMCR[PBSE] is set, you can disconnect PPBS. Otherwise, pull the signal up. • The following signals: SWTE, DSISYNC, DSI64, MODCK[1–2], CNFGS, CHIPID[0–3], RSTCONF and BM[0–2] are used to configure the MSC8102 and are sampled on the deassertion of the PORESET signal. Therefore, they should be tied to GND or VDD either directly or through a pull-down or a pull-up resistor until the deassertion of the PORESET signal. • You must pull up BR, BG, DBG, EXT_BR[2–3], EXT_BG[2–3], EXT_DBG[2–3], and TS if the BCR[EBM] bit is set. • When they are used, you must pull up INT_OUT (if SIUMCR[INTODC] is cleared), NMI_OUT, and IRQxx (if not full drive). Note: For details on configuration, see the MSC8102 User’s Guide and MSC8102 Reference Manual. 4.3 Recommended Clock Connections for Single-Master Mode with DLL Off Use the guidelines shown in Figure 4-4 to connect CLKOUT to a slave device, such as an SDRAM. The zero-delay buffer can use internal or external feedback. Oscillator Buffer MSC8102 CLKIN DLLIN CLKOUT Zero-Delay Buffer SDRAM DLLDIS = 1 Figure 4-4. Example Clock Distribution In Single-Master Mode with DLL Disabled Because the connection uses open loop timing between the internal and external clock (CLKOUT), the design must adhere to the following requirements: • The maximum delay between the CLKOUT pin to the SDRAM must be less than 0.7 ns. • The maximum external load on CLKOUT must not exceed 10 pF. • The zero-delay buffer must have a jitter of less than 0.3 ns. MSC8102 Quad Core Digital Signal Processor, Rev. 12 4-4 Freescale Semiconductor Power Considerations 4.4 Power Considerations The internal power dissipation consists of three components: PINT = PTCORE + PSIU + PBUSES + PPERIPH The power dissipation depends on the operating frequency of the different portions of the chip. To determine the power dissipation at a given frequency, the following equations should be applied: PCORE (fc) = ((PCORE – PLCO)/275) × fc + PLCO PTCORE (fc) = (PCORE × 4) PSIU (fc) = ((PSIU – PLSI)/91.67) × fc + PLSI PPERIPH (fc) = ((PPERIPH – PLPE)/91.67) × fc + PLPE PBUSES (fc) = PBUSES /91.67 × fc Where, fc is the operating frequency in MHz and all power numbers are in mW PLCO is the SC140 Core leakage power PLSI is the SIU leakage power PLPE is the peripheral leakage power To determine a total power dissipation in a specific application, the following equation should be applied for each I/O output pin: P = C × VDDH2 × fs × 10–3 Equation 1 Where: P = power in mW C = load capacitance in pF fs = output switching frequency in MHz. MSC8102 Quad Core Digital Signal Processor, Rev. 12 Freescale Semiconductor 4-5 Design Considerations 4.5 Thermal Design Considerations An estimation of the chip-junction temperature, TJ, in ° C can be obtained from the following: TJ = TA + (Rθ JA × PD) Equation 2 where TA = ambient temperature near the package (° C) Rθ JA = junction-to-ambient thermal resistance (° C/W) PD = PINT + PI/O = power dissipation in the package (W) PINT = IDD × V DD = internal power dissipation (W) PI/O = power dissipated from device on output pins (W) The power dissipation values for the MSC8102 are listed in Table 2-3. The ambient temperature for the device is the air temperature in the immediate vicinity that would cool the device. The junction-to-ambient thermal resistances are JEDEC standard values that provide a quick and easy estimation of thermal performance. There are two values in common usage: the value determined on a single layer board and the value obtained on a board with two planes. The value that more closely approximates a specific application depends on the power dissipated by other components on the printed circuit board (PCB). The value obtained using a single layer board is appropriate for tightly packed PCB configurations. The value obtained using a board with internal planes is more appropriate for boards with low power dissipation (less than 0.02 W/cm2 with natural convection) and well separated components. Based on an estimation of junction temperature using this technique, determine whether a more detailed thermal analysis is required. Standard thermal management techniques can be used to maintain the device thermal junction temperature below its maximum. If TJ appears to be too high, either lower the ambient temperature or the power dissipation of the chip. You can verify the junction temperature by measuring the case temperature using a small diameter thermocouple (40 gauge is recommended) or an infrared temperature sensor on a spot on the device case that is painted black. The MSC8102 device case surface is too shiny (low emissivity) to yield an accurate infrared temperature measurement. Use the following equation to determine TJ: TJ = TT + (θ JA × PD) Equation 3 where TT = thermocouple (or infrared) temperature on top of the package (° C) θ JA = thermal characterization parameter (° C/W) PD = power dissipation in the package (W) Note: See MSC8102, MSC8122, and MSC8126 Thermal Management Design Guidelines (AN2601).
