JL杰理AC6921A蓝牙MP3芯处方案的开发说明.docx
JL杰理AC6921A蓝牙MP3芯片方案开发说明
一、简介
AC6921A作为一个单芯片的蓝牙解决方案，广泛应用于蓝牙音箱、蓝牙对箱、带点阵屏和LED数码管音箱。
是珠海杰理科技推出的一款性价比比较高的产品二、功能特点
*支持蓝牙、USB设备、TF卡、FM、AUX、通话
*支持10个AD按键、支持多路I/O口按键
*外围元件少，芯片四面出脚，有利于生产
*支持摇控功能
*支持点阵屏、数码屏、LCD屏的显示功能
*支持IIS输出
*支持光纤信号输入
*蓝牙版本：兼容蓝牙V5.0+BR+EDR+BLE
三、AC6921A管脚说明
四、芯片资源说明
五、AC6921A与之前蓝牙芯片的功能对比分析
六、AC692N功能选型表
七、AC6921标准原理图
原理图在网上可以下载到更清晰的资料，同时也可以向我们索取。
杰里的所有系列的芯片，都是一个晶圆，只是根据不同的需求，进行不同方式的封装，也就是说AC6920N系列里面SSOP24和LQFP48封装的晶圆是一样的
注意，AC692N系列的芯片是可以反复烧录的，有想法的朋友可以自己摸索的。
八、提醒说明
*芯片为可编程，由于程序是烧录在芯片内部的flash中，所以可以重复擦除*感兴趣的朋友，可以自己开发，因为AC692N系列不需要开发板，不需要烧录器
*如果要自己开发的话，最好要买一个现成的板子，引出基本的gpio和串口、USB口就可以了。

设计注意事项： 1、主控所有电源的退耦电容必须靠近芯片放置，
退耦电容的回路地必须最短回到该电源地. 2、蓝牙匹配电路参数以调试结果为准 3、对FM要求比较高的客户，请预留FM放大电路，
灵敏度可提升2dBu以上。FM信号线铺地,
间距至少0. 6MM以上。qq:298391364
4、为保证产品的安全可靠性，电池必须用带保护板的电池。

蓝牙COB PCB Layout注意事项： 1、蓝牙COB尽量放置于板的边缘，远离主控，喇叭，升压和其它IC 2、蓝牙天线处PCB以下不要走任何信号线，也不要做铺地处理 3、蓝牙COB模块正下方，最好少走线，铺地多一点。 4、蓝牙BT_TX ，BT_RX信号线走线时尽量短，且做包地处理 5、蓝牙PCM信号线也尽量短，且做包地处理 6、供给蓝牙的32K_XO 信号线，最好做包地处理 7、蓝牙COB正下方最好用丝印填充，做隔离处理，以免测试点短路
