HD74BC564AOctal D Type Flip Flops With 3 State OutputsADE-205-041 (Z)1st. EditionFeb. 1994 DescriptionThe HD74BC564A provides high drivability and operation equal to or better than high speed bipolar standard logic IC by using Bi-CMOS process. The device features low power dissipation that is about 1/5 of high speed bipolar logic IC, when the frequency is 10 MHZ. The device has eight edge triger D type flip flops with three state outputs in a 20 pin package. Data at the D inputs meeting set up requirements, are transferred to the Q outputs on positive going transitions of the clock input. When the latch enable goes low, data at the D inputs will be retained at the outputs until latch enable returns high again. When a high logic level is applied to the output control input, all outputs go to a high impedance state, regardless of what signals are present at the other inputs and the state of the storage elements.Features• Input/Output are at high impedance state when power supply is off.• Built in input pull up circuit can make input pins be open, when not used.• TTL level input• Wide operating temperature rangeTa = –40 to + 85°CHD74BC564A2Function TableInputsOutput Control CKD Output QL H LL L H L L X Q 0H X XZH :High level L :Low level X :ImmaterialZ:High impedance :Low to high transitionQ 0:Level of Q before the indicated steady state input conditions were established.Pin ArrangementHD74BC564A3Absolute Maximum RatingsItemSymbol Rating Unit Supply voltage V CC –0.5 to +7.0V Input diode current I IK ±30mA Input voltage V IN –0.5 to +7.5V Output voltage V OUT –0.5 to +7.5V Off state output voltage V OUT(off)–0.5 to +5.5V Storage temperature Tstg–65 to +150°CNote:1.The absolute maximum ratings are values which must not individually be exceeded, andfurthermore, no two of which may be realized at the same time.Recommended Operating ConditionsItemSymbol Min Typ Max Unit Supply voltage V CC 4.5 5.0 5.5V Input voltage V IN 0—V CC V Output voltage V OUT 0—V CC V Operating temperature Topr –40—85°C Input rise/fall time*1t r , t f—8ns/VNote:1.This item guarantees maximum limit when one input switches.Waveform: Refer to test circuit of switching characteristics.HD74BC564A Logic Diagram4HD74BC564A5Electrical Characteristics (Ta = –40°C to +85°C)Item Symbol VCC(V)Min Max Unit Test ConditionsInput voltage V IH 2.0—V V IL —0.8V Output voltageV OH 4.5 2.4—V I OH = –3 mA 4.5 2.0—V I OH = –15 mA V OL4.5—0.4V I OL = 24 mA 4.5—0.5V I OL = 48 mA Input diode voltage V IK 4.5—–1.2V I IN = –18 mA Input currentI I5.5—–250µA V IN = 0 V 5.5— 1.0µA V IN = 5.5 V 5.5—100µA V IN = 7.0 V Short circuit output current*1I OS 5.5–100–225mA V IN = 0 or 5.5 V Off state output current I OZH 5.5—50µA V O = 2.7 V I OZL 5.5—–50µA V O = 0.5 V Supply currentI CCL 5.5—29.5mA V IN = 0 or 5.5 V All outputs is “L”I CCH 5.5— 2.5mA V IN = 0 or 5.5 V All outputs is “H”I CCZ 5.5— 2.5mA V IN = 0 or 5.5 V All outputs is “Z”I CCT *25.5—1.5mAV IN = 3.4 or 0.5 V Notes :1.Not more than one output should be shorted at a time and duration of the short circuit should notexceed one second.2.When input by the TTL level, it shows I CC increase at per one input pin.HD74BC564A6Switching Test Method (C L = 50 pF)Ta = 25°C V CC = 5.0 VTa = –40 to 85°C V CC = 5.0V ±10%Item SymbolMin Max Min Max Unit Test Conditions Propagation CK → Q t PLH3.08.0 3.010.0nsSee under figuredelay time t PHL 3.08.0 3.010.0Output enable time t ZH 3.09.0 3.011.0ns t ZL 3.09.0 3.011.0Output disable time t HZ 3.08.0 3.010.0ns t LZ 3.08.0 3.010.0Setup time t s (H) 2.0— 2.0—ns t s (L) 2.0— 2.0—Hold time t h (H) 2.0— 2.0—ns t h (L) 2.0— 2.0—Pulse width t w (H) 6.0— 6.0—ns t w (L) 6.0—6.0—Input capacitance C IN 3.0(Typ)—pF V IN = V CC or GND Output capacitanceC O15.0(Typ)—pFV O = V CC or GNDTest CircuitHD74BC564A Waveforms-1Waveforms-27HD74BC564A Waveforms-38HD74BC564A Package Dimensions9HD74BC564A10HD74BC564A11Cautions 1.Hitachi neither warrants nor grants licenses of any rights of Hitachi’s or any third party’s patent,copyright, trademark, or other intellectual property rights for information contained in this document.Hitachi bears no responsibility for problems that may arise with third party’s rights, includingintellectual property rights, in connection with use of the information contained in this document.2.Products and product specifications may be subject to change without notice.

FUNCTIONAL DESCRIPTION(Figure 6)The NE564 is a monolithic phase-locked loop with a post detection processor. The use of Schottky clamped transistors and optimized device geometries extends the frequency of operation to greater than 50MHz.In addition to the classical PLL applications, the NE564 can be used as a modulator with a controllable frequency deviation.The output of the PLL can be written as shown in the following equation:V O =(f IN - f O)K VCO(1)K VCO = conversion gain of the VCOf IN = frequency of the input signalf O = free-running frequency of the VCOThe process of recovering FSK signals involves the conversion of the PLL output into logic compatible signals. For high data rates, a considerable amount of carrier will be present at the output of the PLL due to the wideband nature of the loop filter. To avoid the use of complicated filters, a comparator with hysteresis or Schmitt trigger is required. With the conversion gain of the VCO fixed, the output voltage as given by Equation 1 varies according to the frequency deviation of f IN from f O. Since this differs from system to system, it is necessary that the hysteresis of the Schmitt trigger be capable of being changed, so that it can be optimized for a particular system. This is accomplished in the 564 by varying the voltage at Pin 15 which results in a change of the hysteresis of the Schmitt trigger. For FSK signals, an important factor to be considered is the drift in the free-running frequency of the VCO itself. If this changes due to temperature, according to Equation 1 it will lead to a change in the DC levels of the PLL output, and consequently to errors in the digital output signal. This is especially true for narrowband signals where the deviation in f IN itself may be less than the change in f O due to temperature. This effect can be eliminated if the DC or average value of the signal is retrieved and used as the reference to the comparator. In this manner, variations in the DC levels of the PLL output do not affect the FSK output.VCO SectionDue to its inherent high-frequency performance, an emitter-coupled oscillator is used in the VCO. In the circuit, shown in the equivalent schematic, transistors Q21 and Q23 with current sources Q25 - Q26 form the basic oscillator. The approximate free-running frequency of the oscillator is shown in the following equation:f O≅122 R C (C1 + C S)(2)R C = R19 = R20 = 100Ω (INTERNAL)C1 = external frequency setting capacitorC S = stray capacitanceVariation of V D (phase detector output voltage) changes the frequency of the oscillator. As indicated by Equation 2, the frequency of the oscillator has a negative temperature coefficient due to the monolithic resistor. To compensate for this, a current I R with negative temperature coefficient is introduced to achieve a low frequency drift with temperature.Phase Comparator SectionThe phase detection processor consists of a doubled-balanced modulator with a limiter amplifier to improve AM rejection.Schottky-clamped vertical PNPs are used to obtain TTL level inputs. The loop gain can be varied by changing the current in Q4 and Q15 which effectively changes the gain of the differential amplifiers. This can be accomplished by introducing a current at Pin 2.Post Detection Processor SectionThe post detection processor consists of a unity gain transconductance amplifier and comparator. The amplifier can be used as a DC retriever for demodulation of FSK signals, and as a post detection filter for linear FM demodulation. The comparator has adjustable hysteresis so that phase jitter in the output signal can be eliminated.As shown in the equivalent schematic, the DC retriever is formed by the transconductance amplifier Q42 - Q43 together with an external capacitor which is connected at the amplifier output (Pin 14). This forms an integrator whose output voltage is shown in the following equation:V O =g MC2(3)V IN dtg M = transconductance of the amplifierC2 = capacitor at the output (Pin 14)V IN = signal voltage at amplifier inputWith proper selection of C2, the integrator time constant can be varied so that the output voltage is the DC or average value of the input signal for use in FSK, or as a post detection filter in linear demodulation.The comparator with hysteresis is made up of Q49 - Q50 with positive feedback being provided by Q47 - Q48. The hysteresis is varied by changing the current in Q52 with a resulting variation in the loop gain of the comparator. This method of hysteresis control, which is a DC control, provides symmetric variation around the nominal value.Design FormulaThe free-running frequency of the VCO is shown by the following equation:(4)f O≅122 R C (C1 + C S)R C = 100ΩC1 = external cap in faradsC S = stray capacitanceThe loop filter diagram shown is explained by the following equation:(5)f S =11 + sRC3(First Order)R = R12 = R13 = 1.3kΩ (Internal)*By adding capacitors to Pins 4 and 5, a pole is added to the loop transfer atω =1RC3NOTE:*Refer to Figure 6.SR01035Figure 11.

对汽车⽚上系统采⽤双核架构1. 简介汽车SoC⼀直以来都采⽤单核结构，因为它们不需要执⾏⼤量的计算或运⾏⾼端应⽤。

汽车系统相对简单，与其相关的应⽤和SoC也是如此。

随着汽车内部空间越来越多地采⽤电⼦设备，SoC也变得越来越复杂。

现在，业界的焦点是将汽车的⼤部分置于电⼦控制之下。

⽬前⽣产的⾼端汽车提供了电⼦稳定控制（ESC）、牵引控制系统（TCS）、⾼级驾驶员辅助系统（ADAS）等等。

这些特性要求在汽车的核⼼使⽤复杂的SoC，能够从多个外围设备以较快的速度收集、处理和传输数据。

不管单核的运⾏频率有多⾼，在执⾏多个任务时，它始终存在性能瓶颈和⼀些挑战。

以较⾼频率运⾏的单核会消耗更多的功率。

因此，单核架构⽆法满⾜超低功率应⽤的需求。

与基于单核的架构相⽐，基于双核的SOC架构在性能和功率消耗⽅⾯实现了更好的平衡。

因此，双核SoC⽬前已经被⼤量应⽤于汽车设计。

除了提供⽐单核更⾼的性能外，基于双核的架构还被⽤于安全应⽤。

安全性是汽车制造商⽐较关⼼的主要问题之⼀。

随着更多复杂应⽤的引⼊，硬件或软件出现故障的机率也⼤⼤增加。

汽车的设计必须⾜够可靠，从⽽能够检测出任何故障并采取相应的修复措施。

基于双核的SoC的架构优势也使它们受到安全应⽤的青睐。

本⽂将介绍汽车SoC中采⽤的各种双核架构• 异构双核架构• 同构双核架构1. 锁步模式（LSM）2. 去耦并⾏模式（DPM）2. 异构双核架构：顾名思义，异构架构具有两个不同的内核：由于这种架构含有两个内核，并且这两个内核分别使⽤了较⾼和较低的配置，因此较⼩的内核也被称为协处理器。

其中，主内核⽤于执⾏批量应⽤处理，⽽较⼩的内核⽤于处理⼀些不太复杂的操作，⽐如持续在I/O上发送数据。

因此即使有第⼆个内核存在，由于它的作⽤是⽀持或补充主内核，因此仍称为协处理器。
