微处理器 TMP87P38N-3DV3控制系统是海信TB1238机心终端设计的最后一个版本,它是在TMP87P38N-1P08控制系统的基础上,在性能上经过完善后的产物。由于 TMP87P38N-3680、TMP87P38N-1P08、TMP87P38N-3DV3控制系统具备先进的功能特点,使市场销售量很大。(2)CPU 系统控制电路的重要引脚(见表2):电源、时钟振荡、复位电平是 CPU 系统控制电路工作的必备条件,TB1238机心系统控制电路的工作也不例外。CPU 系统控制电路的(42)脚是+5V 电源供电脚,(31)、(32)脚外围元件 Z701、C712、C713与内部门电路一起构成
Microprocessor The TMP87P38N-3DV3 control system is the last version of the Hisilicon TB1238 Mobile Terminal Design. It is based on the TMP87P38N-1P08 control system and is a performance-optimized product. As TMP87P38N-3680, TMP87P38N-1P08, TMP87P38N-3DV3 control system with advanced features that make the market a great deal of sales. (2) CPU system control circuit of the important pin (see Table 2): power, clock oscillation, reset level is the prerequisite for the work of the CPU system control circuit, TB1238 mechanical heart system control circuit work is no exception. (42) of the CPU system control circuit is + 5V power supply pin, (31), (32) The external components Z701, C712, C713 form together with the internal gate
