楼主，我现在刚开始做博通蓝牙芯片的开发，用的是BCM20730，我现在不知道这个开发流程是怎么样的，公司现在要做BCM20730做蓝牙键盘，板子都弄好了，就差程序了，但我连怎么开始都不知道，楼主能指点一二吗，谢谢了！（PS.楼主可以去我的帖子里回答拿积分的哦http://bbs.csdn.net/topics/390814423）

The Microchip Technology Inc. 93C76/86 are 8K and 16K low voltage serial Electrically Erasable PROMs. The device memory is configured as x8 or x16 bits depending on the ORG pin setup. Advanced CMOS technology makes these devices ideal for low power non-volatile memory applications. These devices also have a Program Enable (PE) pin to allow the user to write protect the entire contents of the memory array. The 93C76/86 is available in standard 8-pin DIP and 8- pin surface mount SOIC packages
