Compared with the prior art, the utility model, following beneficial effect has: 1, need not paste again when producing the remote controller and adorn outside memory chip, effective consumption that reduces design circuit board area, saves paster material tin cream, reduction resource. 2, assemble a chip less, improved the production efficiency of mill and user's product and used reliability, while reduce production manpower and the cost that has reduced the remote controller.
Description
Technical field
This utility model relates to field of remote-control unit, particularly relates to a kind of single-chip learning type infrared remote-controller.
Background technology
The learning type infrared remote-controller of Set Top Box standard configuration, when typically requiring dead battery or take off, remote controller
Learning region (study save the power supply of TV remote controller, TV/AV, volume+,-etc. button data) preserve
Key code value can not lose, and the data of chip are typically maintained in the middle of the SRAM of IC, the number of SRAM
Needing certain voltage according to preserving, when taking off battery, SRAM voltage is less than specification, the number that SRAM preserves
According to will losing or change, thus cause the learning region key code value mistake ensured, it is impossible to remote-controlled television set,
Preserved so the data in SRAM must be write in special storage chip, it is achieved study code value breaks
Electricity does not forever fall.Learning type infrared remote-controller typically uses dual chip design, i.e. one master chip to be used at present
Realizing signaling and key scan, another one chip is used for storing study key code value, it is ensured that remote controller power-off
After, learning code does not falls.Such structure has the drawback that: need additional storage chip, and cost is high,
Two chip production assembling troubles, when user uses, fault rate is the highest.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of cost-effective and money
Source and the single-chip learning type infrared remote-controller of raising production efficiency.
For achieving the above object, this utility model can be achieved by the following technical programs:
Single-chip learning type infrared remote-controller, including chip, remote controller key keyboard and battery, described remote control
Device key board and battery are connected with chip respectively, also include infrared transmitting tube, the sun of described infrared transmitting tube
Pole is connected with anode, and its negative electrode is connected with chip, is parallel with electric capacity, institute between described battery and chip
CPU on sheet, SRAM memory and MTP memorizer, described SRAM memory it is integrated with in stating chip
It is connected with CPU respectively with MTP memorizer.
Further, otp memory on sheet, described otp memory and CPU it are also integrated with in described chip
Connect.
Further, also including learning display lamp, the anode of described study display lamp is connected with anode,
Its negative electrode is connected with chip.
Further, it is in series with resistance between negative electrode and the chip of described study display lamp.

Connect.The study code value of remote controller is stored in MTP memorizer MTP ROM.
Preferably, otp memory OTP ROM, otp memory OTP ROM it are also integrated with in chip
It is connected with CPU, the study remote controller function executing generation that otp memory is write for storage programming language
Code.
Preferably, also including learning display lamp D2, the anode of study display lamp D2 is connected with anode,
Its negative electrode is connected with chip, and study display lamp D2 is used for indicating learning state and process.Study display lamp D2
Negative electrode and chip between be in series with resistance R, resistance R to study display lamp D2 carry out current limliting and blood pressure lowering, protect
Card study display lamp D2 is operated in nominal parameter.
Preferably, the voltage of battery is 1.5V～5.5V.
This utility model is at chip internal integrated MTP memorizer MTP ROM, the number that will preserve in SRAM
According to being stored directly in MTP memorizer MTP ROM, it is achieved the purpose that study code value does not falls.
For a person skilled in the art, can be made other each according to above technical scheme and design
Kind corresponding change and deformation, and all these changes and deformation all should belong to this utility model right
Within the protection domain required.
