The CHT0818 is a single-chip micro-computer IC which is widely used in Changhong series large-screen color TV sets, such as the Changhong CH-10 cassette mechanism. 1.Its functional features. The CHt0818 IC's internal part is mainly made up of central processing unit (CPU), clock oscillation circuit, reset control circuit, I2C bus control circuit, key command decoding circuit, sound system control circuit, remote-control command signal processing circuit, degaussing control circuit, memory control circuit, screen display character generating and processing circuit and other some control and auxiliary function circuits and so on. Its internal circuit diagram and pin's function and signal flowing is shown in picture 1. The picture 1 shows the CHT0818 IC's internal circuit diagram and pin's function and signal flowing. 2.Its pin's function and data. The CHT0818 IC uses 42-pin dual package. Its pin's function is shown in picture 1 and its pin's letter code and data is listed in table 1. The table 1 shows the CHT0818 IC's pin's letter code and data.
