IA611开发板套件编程器的评估板-扩展板子卡规格书PDF中文资料

IA611属于开发板套件编程器的评估板-扩展板子卡。由楼氏电子(苏州)有限公司制造生产的IA611评估板 - 扩展板，子卡评估和扩展板及子卡用于向微控制器平台添加功能，它们可以堆叠到现有针座或预配置的附件端口上。常见功能类型包括放大器、雾化器、音频、时钟定时、接口连接性、数据获取/记录、显示、人机界面、存储器、电机驱动器、光电器件、电源管理、原型设计、继电器和晶体管、RF 和传感器阵列。

The IA611 is an “always-on” Acoustic Processor featuring Voice Wake and Voice ID keyword detector, a three second buffer, and Knowles’ proven high performance acoustic SiSonicTM MEMS technology in a single, miniature, top-port package. The IA611 offers flexibility by supporting the most relevant audio and data interfaces. Its integrated programmable DSP with 248 KBytes of RAM is available for customer and 3rd party algorithms, enabling unlimited creativity. The solution pushes the system performance to ultra-low power with its custom core design, and accelerates times to market with its unique combination of hardware, software, and firmware.
