前言
本文档为创龙科技SOM-TLT507工业核心板硬件说明书，主要提供SOM-TLT507工业核心板的产品功能特点、技术参数、引脚定义等内容，以及为用户提供相关威廉希尔官方网站设计指导。

创龙科技SOM-TLT507是一款基于全志科技T507-H处理器设计的4核ARM Cortex-A53全国产工业核心板，主频高达1.416GHz。核心板CPU、ROM、RAM、电源、晶振等所有元器件均采用国产工业级方案，国产化率100%。

核心板通过邮票孔连接方式引出MIPI CSI、HDMI OUT、RGB DISPLAY、LVDS DISPLAY、CVBS OUT、2x EMAC、4x USB2.0、6x UART、SPI、TWI等接口，支持双屏异显、G31 MP2 GPU、4K@60fps H.265视频硬件解码、4K@25fps H.264视频硬件编码。核心板经过专业的PCB Layout和高低温测试验证，稳定可靠，可满足各种工业应用环境。

引脚说明2.1 引脚排列

核心板邮票孔引脚采用2x 32pin + 2x 53pin，共170pin规格，引脚排列如下图所示。

图 7 核心板引脚排列示意图

2.2 引脚定义

核心板邮票孔引脚定义如下表。其中“邮票孔引脚号”为核心板邮票孔引脚序列号；“芯片引脚号”为CPU引脚序列号；“CPU引脚信号名称”为处理器芯片管脚名称，包含全部复用功能信号；“引脚功能”为核心板引脚推荐功能描述；“参考电平”为核心板引脚工作电平标准。

备注：

（1） “芯片引脚号”为“-”表示该引脚信号未连接至CPU引脚。

（2）部分核心板引脚资源存在复用关系，例如信号B22/LCD-D4/LVDS0-V2P/3V3（如下图），在评估底板既作为TFT LCD功能，又作为LVDS功能，两者功能复用该信号。

2.3 内部引脚使用说明

“邮票孔引脚号”为“-”表示该引脚未引出至核心板邮票孔，“引脚功能”为“-”表示该引脚在核心板上未使用。

备注：由于S-TWI0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，建议进行底板设计时尽量选用其他TWI总线。
