2.3 内部引脚使用说明
下表为核心板内部引脚的使用情况说明,“B2B引脚号”为"-"表示该引脚在核心板内部使用,且未引出至B2B连接器;否则代表核心板内部已使用且同时引出至核心板B2B连接器。
备注:由于I2C1已连接至核心板的PMIC电源管理芯片,因此从系统稳定性角度考虑,进行底板设计时,建议尽量选用其他I2C总线。I2C1在核心板上未添加上拉电阻,当前使用软件上拉处理,为保险起见,请务必在底板添加4.7K上拉电阻至3.3V。

空闲状态:系统启动,评估板不接入其他外接模块,不执行程序。
满负荷状态:系统启动,评估板不接入其他外接模块,运行DDR压力读写测试程序,4个ARM Cortex-A53核心的资源使用率约为100%。
3.3 热成像图
核心板在常温环境、满负荷状态下稳定工作10min后,分别在安装散热片与未安装散热片的情况下,测得热成像图如下所示。其中红色测温点为最高温度点;左上角温度为画面中心点温度。未安装散热片时,最高温度点为58.9℃;安装散热片时,最高温度点为52.0℃。
备注:不同测试条件下结果会有所差异,请参考测试结果,并根据实际情况合理选择散热方式。

5 底板设计注意事项
5.1 最小系统设计
基于SOM-TLIMX8MP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_5V0_SOM
VDD_5V0_SOM为核心板的主供电输入,电源功率建议参考评估板按最大10W进行设计。
VDD_5V0_SOM在核心板内部未预留总电源输入的储能大电容,底板设计时请参考评估底板原理图,在靠近核心板电源输入端放置总容值为50uF左右的储能电容。
(2) VDD_5V0_MAIN & VDD_3V3_MAIN & VDD_3V3_PCIe_5G & VDD_1V8_MAIN
VDD_5V0_MAIN、VDD_3V3_MAIN、VDD_3V3_PCIe_5G、VDD_1V8_MAIN为评估底板提供的外设接口电源。为使VDD_5V0_MAIN、VDD_3V3_MAIN、VDD_3V3_PCIe_5G、VDD_1V8_MAIN满足核心板的上电、掉电时序要求,推荐使用VDD_3V3_SOM控制VDD_5V_MAIN、VDD_3V3_MAIN、VDD_3V3_PCIe_5G和VDD_1V8_MAIN的电源使能。
5.1.2 系统启动配置
核心板内部未对BOOT MODE[0:3]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 BOOT SET电路设计
5.1.3 系统复位信号
(1) PMIC_KEY_RSTn(PMIC_RST_B)
PMIC_KEY_RSTn为PMIC的上电复位输入引脚,可用于控制i.MX 8M Plus复位输入引脚,以及外设接口的复位。PMIC_KEY_RSTn在PMIC内部已上拉至1.8V,无需使用时,请悬空处理,以免影响上电时序。
图 19 PMIC_KEY_RSTn电路设计
(2) J29/POR_B
J29/POR_B为CPU复位输入引脚,同时与PMIC的复位输出POR_B引脚相连,可用于输出控制外设接口的复位。该复位在VDD_3V3_SOM之后、延迟21.2ms拉高,如下图所示。
当使用该复位作为其他外设复位信号时,为避免外设掉电休眠时影响J29/POR_B/PU/1V8复位输入信号的电平,导致系统复位,需考虑增加缓冲器隔离J29/POR_B/PU/1V8复位输入信号。
图 21 J29/POR_B信号缓冲隔离电路设计
(3) G22/ONOFF
G22/ONOFF为CPU的开关机控制引脚,长按5s以上CPU将会关机,再按1s左右CPU将切换为开机。核心板内部已设计100K上拉电阻,无需使用时,请悬空处理。
图 22 G22/ONOFF引脚电路设计
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uSDHC2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。
备注:评估底板支持通过Micro SD或USB3.0 DRD(USB1)接口快速固化系统至eMMC,可根据实际情况,选择保留Micro SD、USB3.0 DRD接口。
5.2.2 保留UART2接口
评估底板将AF6/UART2_RXD/3V3和AH4/UART2_TXD/3V3引脚通过CH340T芯片引至Type-C接口,作为系统调试串口使用,底板设计时建议保留UART2作为系统调试串口。
6 附图最小系统设计
如下为基于我司SOM-TLIMX8MP核心板的最小系统电路设计,可作为参考使用。
