iCore-3568JQ最小系统有那些条件？
iCore-3568JQ最小系统有那些条件？我开机 后只有40-50ma是什么问题？
你好。最小系统，你指的是什么，硬件最小系统？还是指功耗方面的问题 硬件 硬件最小电路跟单片机最小电路差不多，时钟、电源（PMU）、复位、启动介质等电路；底板设计参考ITX-3568JQ 核心板说明上
1. VCC5V0_SYS电源是核心板系统供电电源，电压范围4.8V-5.5V;核心板内部5V—>3.3V给PMIC供电。
2.37:VD_IN脚是强制开机管脚，该管脚只要电压大于3V，核心板就会自动开机。如果不需要上电自动开机，该脚可以NC。
其它的时钟不在核心板上面吗？还有其它的条件吗？
我自己做了个底板，只提供sys_5V电源，没有外设，开机后会无法启动。循环打log
