一、A12机心简介海信 A12机心电视机是海信2000年研制投产的一款单片机心。该机心采用日本三洋公司大规模集成电路 LA76810作为彩色解码、亮度和行、场同步等小信号处理,同时配合三洋公司 LC8633XX 系列彩色电视机专用微处理器和 LA784X 系列场输出集成电路,整机线路比较简单,外围元件也很少,只有38MHz 中周一个可调元件(54cm/21英寸机型)。该机心电视机根据软件功能区别主要可分成两大类:一类以 TC2181F、TC2189A、TC2199D、TC2588L 型电视机为代表;另一类以 TC2110L、TC2166L、TC2175L、TC2199、TC2199A、TC2588D、TF2110D 型电视机为代表。这两类机器共同的特点是采用 I~2C 总线控制,具
First, the A12 movement Brief introduction Hisense A12 motorized TV Hisense 2000 is the development and production of a single-chip computer. The movement using Japan Sanyo large-scale integrated circuit LA76810 as color decoding, brightness and line, field synchronization and other small signal processing, at the same time with Sanyo LC8633XX series of color TV special microprocessors and LA784X series of field output integrated circuits, the whole machine The circuit is relatively simple, there are few external components, only 38MHz mid-week adjustable components (54cm / 21 inch models). The movement of the TV according to the software features can be divided into two main categories: one with TC2181F, TC2189A, TC2199D, TC2588L-type TV as the representative; the other to TC2110L, TC2166L, TC2175L, TC2199, TC2199A, TC2588D, TF2110D TV is the representative. The common feature of these two types of machines is the use of I ~ 2C bus control, with
