Background technology
Because the progress of semiconductor technology, electronic circuit is able to miniaturization and (integratedcircuit, mode IC) realizes, to be applied in the various electronic product with integrated circuit.Integrated circuit is by early stage small scale integration (Small-Scale Integrated circuit, SSI) be developed to now VLSI (very large scale integrated circuit) (Ultra-Large Scale Integrated circuit, ULSI), its function of integrating is also more and more.
Integrated circuit is normally as purposes such as control, computing or drivings, or integrates at least wherein two kinds of functions.And the function of integrating along with integrated circuit is many more, and its perimeter component that need control or drive is also many more, and its required I/O (I/O) terminal is also more and more certainly.With the lead-out terminal that only has output function is example, because the distance between each lead-out terminal must limit to some extent avoiding phase mutual interference even short circuit, so the volume of integrated circuit must just be enough to hold more lead-out terminal along with increasing.Can't meet the demand of miniaturization of electronic products now and increase volume, and bigger integrated circuit means that also price also can increase thereupon.
In addition, also can not utilize the mode of TCM to come processing signals if do not increase the quantity of lead-out terminal.Integrated circuit can be exported two kinds of control signals at different time order and functions by a lead-out terminal wherein, to control different perimeter components.Yet this kind practice can't make this lead-out terminal output signal to different perimeter components simultaneously and control simultaneously, also will cause the inconvenience in the use.
Therefore, how to provide a kind of electronic module and control method thereof, make integrated circuit can control a plurality of perimeter components simultaneously, to save the occupied space of integrated circuit, real one of the important topic that belongs to.
Summary of the invention
Because above-mentioned problem, purpose of the present invention is for providing a kind of electronic module and control method thereof that makes integrated circuit can control a plurality of perimeter components simultaneously.
For reaching above-mentioned purpose, the invention provides a kind of electronic module and comprise an integrated circuit unit, a signal separation unit, one first controlled cell and one second controlled cell.Integrated circuit unit has a lead-out terminal, and exports a composite signal by lead-out terminal.Signal separation unit receives composite signal, and produces one first control signal and one second control signal according to this at least.First controlled cell receives first control signal, and second controlled cell receives second control signal.
For reaching above-mentioned purpose, the invention provides a kind of control method of electronic module, it comprises following steps: the lead-out terminal by an integrated circuit unit is exported a composite signal; By a signal separation unit composite signal is separated to produce one first control signal and one second control signal at least; First control signal is transferred to one first controlled cell; And second control signal transferred to one second controlled cell.
In a preferred embodiment of the present invention, signal separation unit has at least one filtering circuit, filtering circuit can be high-pass filtering circuit (high-pass filter, HPF), low-pass filter circuit (low-pass filter, LPF), bandwidth-limited circuit (band-pass filter, BPF) or band scold filtering circuit (band-stop filter BSF), convert first control signal to so that composite signal is separated.
In a preferred embodiment of the present invention, signal separation unit has an amplifying circuit, composite signal is converted to second control signal.
From the above, utilize signal separation unit to isolate first control signal and second control signal according to electronic module of the present invention and control method thereof, and transfer to different controlled cell (first controlled cell and second controlled cell) according to this respectively to control simultaneously by the composite signal of integrated circuit unit output.So, can make the integrated circuit unit increase of the less lead-out terminal of configuration can control the quantity of perimeter component, and then can reduce the occupied space of integrated circuit unit, or make integrated circuit unit can have more function.

Embodiment
Hereinafter with reference to relevant drawings, a kind of electronic module and control method thereof according to preferred embodiment of the present invention are described, wherein identical assembly will be illustrated with identical reference marks.
Please refer to shown in Figure 1ly, the electronic module 1 of preferred embodiment of the present invention for example can be applicable in the electronic calculator.Electronic module 1 comprises an integrated circuit unit 11, a signal separation unit 12, one first controlled cell 13 and one second controlled cell 14.Wherein, integrated circuit unit 11 electrically connects with signal separation unit 12, and exports a composite signal SC to signal separation unit 12.Signal separation unit 12 electrically connects with first controlled cell 13 and second controlled cell 14 respectively, and produce one first control signal SC1 and one second control signal SC2 according to composite signal SC, and the first control signal SC1 is transferred to first controlled cell 13, the second control signal SC2 is transferred to second controlled cell 14.
So, by the composite signal that single lead-out terminal is exported, promptly can control first controlled cell 13 and second controlled cell 14 simultaneously through the follow-up signal separate mode.
Below please refer to Fig. 2, the actual operation of the electronic module 1 of preferred embodiment of the present invention is described with example.
As shown in Figure 2, integrated circuit unit 11 for example is a microcontroller (MCU) or a CPU (central processing unit) (CPU), and it has a lead-out terminal 111 at least, and by lead-out terminal 111 output composite signal SC.In the present embodiment, integrated circuit unit 11 more can have a plurality of terminals, and it can be used as the function of input terminal, lead-out terminal or input/output terminal.In addition, the signal that composite signal SC for example includes high and low frequency and is transmitted therein simultaneously.
First controlled cell 13 can be an image control module, a sound control module or a luminous controling unit.In the present embodiment, be example with the image control module, first controlled cell 13 for example has a display control circuit 131 and can use for example change color of the display frame of control display after receiving the first control signal SC1.
Second controlled cell 14 also can be an image control module, a sound control module or a luminous controling unit.In the present embodiment, be example with the sound control module, second controlled cell 14 for example has a buzzer drive circuit 141 and a hummer 142.Buzzer drive circuit 141 receives the second control signal SC2, and output drive signal is sounded to drive hummer 142 according to this.Because buzzer drive circuit 141 only can the start according to high-frequency signal (for example 4KHz), when therefore only in composite signal SC, including radio-frequency component, just can drive hummer 142 starts, and will can not respond for the low-frequency component among the composite signal SC.
Please refer to shown in Figure 4ly, the control method of the electronic module of preferred embodiment of the present invention comprises step S01 to step S04.Below, please be simultaneously with reference to Fig. 1 and shown in Figure 4.
