5 底板设计注意事项
5.1 最小系统设计
基于SOM-TL64x核心板进行底板设计时，请务必满足最小系统设计要求，具体如下。
5.1.1 电源设计说明
（1） VDD_5V_MAIN
VDD_5V_MAIN为核心板的主供电输入，以及为底板其它外设供电，电源功率建议按最大10W进行设计。
图 13
VDD_5V_MAIN在核心板内部未预留总电源输入的储能大电容，底板设计时请参照评估底板原理图，在靠近B2B连接器焊盘位置放置储能大电容。
图 14
（2） VDD_3V3_SOM_OUT
VDD_3V3_SOM_OUT为BOOTMODE[0:15]信号的上拉配置电源，以及底板电源使能端的上拉配置电源，最大电流约为50mA，请勿用于其他负载供电。
图 15
（3） VDD_3V3_MAIN
VDD_3V3_MAIN为评估底板外设接口电源。为使VDD_3V3_MAIN满足处理器的上电、掉电时序要求，推荐参考如下电路进行电源使能设计。
图 16
图 17
5.1.2 系统启动配置
由于BOOTMODE[0:15]引脚与GPMC存在复用关系，因此若使用GPMC外接设备，请保证CPU在上电初始化过程中BOOTMODE[0:15]引脚电平不受外接设备的影响，以免导致CPU无法正常启动。
核心板内部未对BOOTMODE[0:15]引脚进行上下拉配置，底板设计时，请参考评估底板BOOT SET部分电路进行启动配置电路设计。
图 18
5.1.3 系统复位信号
（1） <POR_IN>/PU/3V3
<POR_IN>/PU/3V3为核心板的上电复位输入引脚，核心板已上拉10K电阻，默认情况请悬空处理。
（2） E17/<PORz_OUT>/PD/3V3
E17/<PORz_OUT>/PD/3V3为核心板的复位输出引脚，核心板内部已设计10K下拉电阻，默认情况请悬空处理。对于有严格要求上电复位顺序的外设，需结合外设的上电时序和复位时序来使用E17/<PORz_OUT>/PD/3V3。
（3） E18/<RESET_REQz>/PU/3V3
E18/<RESET_REQz>/PU/3V3为CPU的Warm_Reset输入引脚，核心板已上拉10K电阻，默认情况请悬空处理。
（4） B12/<MCU_RESETz>/PU/3V3
B12/<MCU_RESETz>/PU/3V3为MCU域的Warm_Reset输入引脚，核心板已上拉100K电阻，默认情况请悬空处理。
5.2 其他设计注意事项
5.2.1 保留Micro SD接口
评估底板通过MMC1总线引出Micro SD接口，主要用于调试过程中使用Linux系统启动卡来启动系统，或批量生产时可基于Micro SD卡快速固化系统至eMMC，底板设计时建议保留此外设接口。
5.2.2 保留UART0接口
评估底板将UART0_RXD和UART0_TXD引脚通过CH340T芯片引至Micro USB接口，作为系统调试串口使用，底板设计时建议保留UART0作为系统调试串口。
