该CPU为日本三菱公司生产,是一种八位单片CPU。应用电路如图1所示(图示海信TC2125C彩电)。一、CPU引脚和外电路介绍 1.CPU的基本工作条件 (1)(42)脚为Vcc 5V电源供电端。在待机时,5V供电电压由副电源电路产生12V左右电压.经V581、VD581、R582稳压后提供的。如主电源电路工作后,主电源产生15V电压,再经电阻R583限流后所得的电压与5V稳压器来完成。
The CPU for the Japanese company Mitsubishi, is a single eight-chip CPU. Application circuit shown in Figure 1 (Pictured Hisense TC2125C color TV). A, CPU pin and external circuit description 1.CPU basic working conditions (1) (42) feet Vcc 5V power supply side. In standby, 5V power supply voltage generated by the secondary power supply circuit about 12V. By V581, VD581, R582 regulator provided. Such as the main power circuit work, the main power supply voltage of 15V, and then by the resistor R583 current limit after the resulting voltage and 5V regulator to complete.
