RK3288瑞芯微2014年04月13日发布的旗舰级SoC芯片,也是瑞芯微旗下最早的旗舰级开源芯片,采用ARM A17架构,支持安卓Linux系统。RK3288有着丰富的接口拓展能力,最为一款通用型SoC,广泛应用于商业显示设备、工控设备、视频会议终端、人脸识别设备和ARM集群服务器等产品。RK3288虽然是一款已经发布了7年之久的芯片,可是因为其功能强大、价格合适,成为了经久不衰的一款通用性SoC芯片,目前市场上仍然有很多采用RK3288作为主控芯片的产品。不过因为2021年特殊的供应链情况,产能吃紧,RK3288产能严重不足,交货周期拉长,因此我们更加推荐瑞芯微新近主推的用来替代RK3288的RK3568,该芯片采用4核A55架构,内置独立神经网络处理器,支持更多的高速接口和具备强大编解码能力和视频输入能力,最为重要的是不缺货!

不过为了客户选型需要,下面我们还是介绍一下RK3288,以便客户参考。

Notes  

① :DDR3/LPDDR2/LPDDR3 are not used simultaneously as well as async and sync ddr nand flash

In RK3288, Video decoder (except H.265) and encoder are not used simultaneously because of shared internal buffer

Actual maximum frame rate will depend on the clock frequency and system bus performance

Actual maximum data rate will depend on the clock frequency and JPEG compression rate
