Description
본 발명은 전자기기에 사용되는 EEPROM의 데이터 초기화 기술에 관한 것으로, 특히 EEPROM을 섀시(chassis)에서 분리하지 않고 EEPROM 데이터를 초기화하는데 적합한 EEPROM 데이터 처리 장치 및 초기화 소켓 구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to data initialization techniques for EEPROMs used in electronic devices, and more particularly, to an EEPROM data processing apparatus and initialization socket structure suitable for initializing EEPROM data without detaching the EEPROM from a chassis.
EEPROM(Electrically Erasable Programmable Read-Only Memory)은 대부분의 전자기기에 장착되는 메모리로서, 정상보다 높은 전압을 이용하여 메모리내의 데이터를 반복적으로 지우거나 다시 프로그래밍(기록)할 수 있으며, 전자기기, 특히 TV내에 장착되는 EEPROM은 음량, 음향효과, 화면배색, 채널정보, 사용자정보, 예약정보, 암호 등과 같은 다양한 정보를 수록할 수 있다.EEPROM (Electrically Erasable Programmable Read-Only Memory) is a memory installed in most electronic devices, and it is possible to repeatedly erase or reprogram (write) data in the memory by using a voltage higher than normal. The EEPROM mounted inside can store various information such as volume, sound effect, screen coloration, channel information, user information, reservation information, and password.
이러한 EEPROM은 EPROM 칩과는 달리, 기록된 내용을 수정하기 위해 컴퓨터에서 빼낼 필요는 없지만, 그 제품 특성상 내부 데이터가 순차적으로 정해진 번지에 기록되기 때문에 내용 일부분이 손상될 경우 내부 데이터를 확인하거나 일부 내용을 부분적으로 수정할 수는 없다는 단점이 있다.Unlike the EPROM chip, the EEPROM does not need to be removed from the computer to modify the recorded contents.However, due to its characteristics, the internal data is sequentially recorded at a fixed address. There is a drawback that you cannot modify it partially.
이러한 이유로 인해 제품 개발시 EEPROM 내부 데이터에 오류가 존재할 경우, 납땜 도구 등을 이용하여 섀시에서 EEPROM을 분리할 수밖에 없으며, 통상적으로 EEPROM의 재활용은 고려되지 않는다.For this reason, if there is an error in the data inside the EEPROM during product development, the EEPROM must be separated from the chassis by using a soldering tool, and the recycling of the EEPROM is not generally considered.
따라서, EEPROM을 섀시에서 분리하지 않고 EEPROM의 데이터를 초기화할 수 있는 기술이 요구된다.Therefore, there is a need for a technique capable of initializing data in the EEPROM without removing the EEPROM from the chassis.
본 발명은 이러한 요구에 부응하여 구현한 것으로, EEPROM 단자와 접속되는 전극을 갖는 덮개식 소켓구조를 EEPROM 상부에 장착하고, 이 소켓구조를 통해 마이컴과 EEPROM간의 데이터 통신을 수행하여 EEPROM 데이터를 소거/재생/초기화하도록 한 EEPROM 데이터 처리 장치 및 초기화 소켓 구조를 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been implemented in response to such a demand. A cover socket structure having an electrode connected to an EEPROM terminal is mounted on an EEPROM, and data communication between the microcomputer and the EEPROM is performed through this socket structure to erase / enable EEPROM data. It is an object of the present invention to provide an EEPROM data processing device and an initialization socket structure for reproducing / initializing.

Control means for erasing, reproducing or initializing the data stored in the EEPROM by performing data communication with the EEPROM, and performing data interfacing between the control means and the EEPROM, which is covered on the upper part of the EEPROM, and is connected to correspond to each terminal of the EEPROM. An EEPROM data processing apparatus including a removable lid socket structure having electrode terminals on a side thereof is provided.
본 발명의 목적을 달성하기 위한 다른 실시예에 따르면, EEPROM의 상부면에 장착되는 덮개식 소켓 구조에 있어서, EEPROM의 각 단자와 전기적으로 대응되게 접속되도록 소켓 구조의 내측면에 부착되는 각각의 전극 단자와, 각각의 전극 단자와 EEPROM의 초기화 신호 공급을 위한 마이크로컴퓨터를 연결하는 와이어를 갖는 초기화 소켓 구조를 제공한다.According to another embodiment for achieving the object of the present invention, in the lid socket structure mounted on the upper surface of the EEPROM, each electrode attached to the inner surface of the socket structure to be electrically connected to each terminal of the EEPROM An initialization socket structure having a terminal and a wire connecting each electrode terminal and a microcomputer for supplying an initialization signal of an EEPROM is provided.
이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예에 대하여 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.
도 1은 본 발명에 따른 EEPROM 데이터 처리 장치의 구성 블록도로서, 키 입력부(100), 마이컴(102), 전원 공급부(104), EEPROM(106)을 포함한다.1 is a block diagram illustrating an EEPROM data processing apparatus according to the present invention, which includes a key input unit 100, a microcomputer 102, a power supply unit 104, and an EEPROM 106.
도시한 바와 같이, 키 입력부(100)는 EEPROM 데이터의 설정을 위한 메뉴 키 신호를 제공하는 역할을 수행하며, 전원 공급부(104)에 의해 전원이 공급되면 마이컴(102)으로 소거, 취소, 초기화 키 신호를 선택적으로 제공하도록 한다.As shown, the key input unit 100 serves to provide a menu key signal for setting the EEPROM data. When the power is supplied by the power supply unit 104, the key input unit 100 erases, cancels, and initializes the key. Optionally provide a signal.
마이컴(102), 예컨대 8비트(bit) 마이크로컴퓨터는 이러한 키 입력부(100)부터의 메뉴 키 신호에 대응하여 EPROM(106)과의 데이터 통신을 수행하여 EEPROM(106)내에 수록된 데이터를 소거 또는 재생 또는 초기화시킨다.The microcomputer 102, for example, an 8-bit microcomputer, performs data communication with the EPROM 106 in response to the menu key signal from the key input unit 100 to erase or reproduce data stored in the EEPROM 106. Or initialize.
예를 들어, 키 입력부(100)로부터 소거 키 신호가 입력되면 마이컴(102)은 EEPROM(106)에 기록된 데이터를 모두 소거하도록 하며, 취소 키 신호가 입력되면 이미 소거한 내용을 다시 재생하도록 EEPROM(106)의 동작을 설정한다. 또한, 초기화 키 신호가 키 입력부(100)로부터 입력되면 마이컴(102)은 EEPROM(106)을 공장 출하 초기 모드로 설정한다.For example, when the erase key signal is input from the key input unit 100, the microcomputer 102 erases all data recorded in the EEPROM 106, and when the cancel key signal is input, the EEPROM replays the contents already erased. An operation of 106 is set. In addition, when the initialization key signal is input from the key input unit 100, the microcomputer 102 sets the EEPROM 106 to the factory default mode.
EEPROM(106)은 전자기기, 특히 TV내에 장착되어 음량, 음향효과, 화면배색, 채널정보, 사용자정보, 예약정보, 암호 등과 같은 다양한 정보를 수록할 수 있으며, 마이컴(102)에 의해 데이터 처리된다.The EEPROM 106 may be mounted in an electronic device, especially a TV, to store various information such as volume, sound effects, screen coloration, channel information, user information, reservation information, password, and the like, and are processed by the microcomputer 102. .
이때, 본 실시예에서는 이러한 EEPROM(106)과 마이컴(102)간의 데이터 처리를 수행함에 있어, 마이컴(102)과 EEPROM(106)의 각 단자를 전기적으로 접속하는 소켓 구조를 구현하였다.At this time, in the present embodiment, in performing the data processing between the EEPROM 106 and the microcomputer 102, a socket structure for electrically connecting the terminals of the microcomputer 102 and the EEPROM 106 is implemented.
즉, 도 2에 도시한 바와 같이, 소켓 구조(200)는 EEPROM(106) 상부에 덮여 마이컴(102)과 EEPROM(106)간의 데이터 인터페이싱을 수행하며, EEPROM(106)의 각 단자(108)와 대응되게 접속되도록 그 내부 측면에 전극 단자(202, 204, 206, 208)가 형성된다.That is, as shown in FIG. 2, the socket structure 200 is covered on the EEPROM 106 to perform data interfacing between the microcomputer 102 and the EEPROM 106, and with each terminal 108 of the EEPROM 106. Electrode terminals 202, 204, 206 and 208 are formed on the inner side thereof so as to correspond correspondingly.
본 실시예에 따른 소켓 구조(200)는 착탈 덮개식이기 때문에 각 전극 단자(202, 204, 206, 208)는 EEPROM(106)의 GND(ground) 단자, SCL(clock) 단자, SDA(data) 단자, Vcc 단자와 접속될 수 있으며, 와이어(wire)에 의해 마이컴(102)과 연결된다. 즉, 마이컴(102)으로부터의 GND 연결 와이어는 전극 단자(202)와, SCL 연결 와이어는 전극 단자(204)와, SDA 연결 와이어는 전극 단자(206)와, Vcc 연결 와이어는 전극 단자(208)와 각각 연결된다.Since the socket structure 200 according to the present embodiment is a removable cover type, each electrode terminal 202, 204, 206, and 208 has a GND (ground) terminal, an SCL (clock) terminal, and an SDA (data) terminal of the EEPROM 106. The terminal may be connected to the Vcc terminal and connected to the microcomputer 102 by a wire. That is, the GND connection wire from the microcomputer 102 is the electrode terminal 202, the SCL connection wire is the electrode terminal 204, the SDA connection wire is the electrode terminal 206, and the Vcc connection wire is the electrode terminal 208. And are connected respectively.
따라서, 마이컴(102)으로부터 제공되는 외부 신호처리 데이터는 소켓 구조(200)내의 각 단자(202, 204, 206, 208)를 통해 EEPROM(106)의 각 단자(108)로 제공될 수 있다.Thus, external signal processing data provided from the microcomputer 102 may be provided to each terminal 108 of the EEPROM 106 through each terminal 202, 204, 206, 208 in the socket structure 200.
본 발명에 의하면, 전극 단자를 갖는 착탈식 소켓 구조에 의해 EEPROM 데이터를 처리하여 EEPROM을 섀시에서 분리하지 않고 반복 재생하여 사용할 수 있는 바, 개발비용을 절감하고 A/S시 작업 시간을 줄일 수 있는 효과가 있다.According to the present invention, the EEPROM data can be processed and replayed repeatedly without being separated from the chassis by the removable socket structure having the electrode terminal, thereby reducing the development cost and reducing the work time during A / S. There is.
이상, 본 발명을 실시예에 근거하여 구체적으로 설명하였지만, 본 발명은 이러한 실시예에 한정되는 것이 아니라, 그 요지를 벗어나지 않는 범위내에서 여러 가지 변형이 가능한 것은 물론이다.As mentioned above, although this invention was concretely demonstrated based on the Example, this invention is not limited to this Example, Of course, various changes are possible within the range which does not deviate from the summary.
