I. Overview.

A8102 is a 2.4GHz ISM audio SOC with low cost.It integrates high speed pipeline 8051 micro controller, 32kbytes in-system programmable flash memory,256B internal SRAM,512B external SRAM,8KB MACSRAM,USB2.0comp smart controller and various powerful features. For audio functions, it Supports adpcm codec, integrated stereo 16-bit CDDEC,48K sample rate,digital mixer,DMA unit,high-speed MAC and pia without tone generator. A8102 Supports fast PLL settling time for frequency hopping system. For packet processing,the A8102 has a built-in QOSMAC (including 8K bytes of data SRAM),auto-packet and auto-retransmit,CRCf or error packet filtering,RSSI for clear channel evaluation,thermal sensor to monitor relative temperature,WOR (wake up RX) function to Support periodic wake up from sleep mode to RX mode and no micro controller interaction to listen to incoming packets. Data whitening for data encryption/decryption. These features are very easy to use when developing wireless systems. All features are Intel packed in a small QFN7x756 large headers package.
