Abstract

본 발명은 내장 프로그램에 의하여 단독적으로 동작하는 장비에 채용하기에 적합하도록 한 플래쉬 이피롬의 프로그램 필드 업그레이드 회로에 관한 것으로서, 이는 프로그램을 필드 업그레이드 시키기 위하여서는 반드시 퍼스컴을 사용해야만 하고 회로 내부에 다운로드 콘트롤을 위한 롬이 별도로 존재하여야만 하며, 또한 다운로드 통신을 위한 시리얼 인터페이스를 내장 해야만 하므로 설치비가 가증됨은 물론 장비의 구성이 복잡해지는 종래 기술의 문제점을 해소코자 한 것이다.The present invention relates to a program field upgrade circuit of flash pyrom which is adapted to be employed in a device that operates solely by a built-in program, which must use a personal computer to field upgrade a program and download control inside the circuit. Since the ROM must exist separately, and the serial interface for download communication must be built, the installation cost is increased and the configuration of the equipment is complicated.

이를 개선코자하여 본 발명은 플래쉬 이피롬을 사용하는 장비에서 프로그램을 필드 업그레이드 할 경우 또는 생산시 초기 프로그램을 로드 할 경우 구성이 간단한 롬팩을 이용하여 프로그램 필드 업그레이드 동작을 실현 할 수가 있는 것이어서 내장 프로그램에 의하여 단독으로 동작하는 장비의 구성을 간략화 시키는 동시에 설치비의 절감을 도모코자 하는 것이다.In order to improve this, the present invention can realize a program field upgrade operation using a ROMpack having a simple configuration when field upgrade of a program or an initial program load during production in a device using a flash pyrom. By simplifying the configuration of the equipment to operate alone to reduce the installation cost.
