FM2010芯片是基于迷你阵列麦克风（SAM）专利技术的，采用空间滤波技术、远/近距离定向拾取声音信号、抑制声学噪声、消除声学回声的低功耗低成本的单芯片。本文将介绍迷你阵列麦克风技术在手持通信产品中的设计要点、FM2010芯片主要功能，及其在GSM手机中的典型应用。

本人提供全套FM2010调试用时的芯片手册，参数调试手册，寄存器手册，及固件程序。-FM2010 chip is based on the mini-array microphone (SAM) patented technology, the use of spatial filtering technique, far/close-directional pick up sound signals, inhibition of acoustic noise, acoustic echo elimination of low-power low-cost single chip. This article will introduce hand-held mini-array microphone technology in the design features of communication products, FM2010 chip main function, and its typical application of GSM mobile phones. I provide a full set of chips when debugging FM2010 manual, parameter commissioning manual, register manuals, and firmware.
