MT8516芯片技术资料分享,下边有网盘下载链接


1 System Overview
MT8516 is a highly integrated connected audio platform incorporating application processing and connectivity subsystems to enable connected audio applications. The chip integrates a Quad-core ARM® Cortex-A35 MPCoreTM operating up to 1.3 GHz. The MT8516 interfaces to NAND flash memory, LPDDR2, LPDDR3, DDR3, DDR3L and DDR4 for optimal performance and also supports booting from eMMC to minimize the overall BOM cost. In addition, an extensive set of interfaces such as TDM/PDM inputs are included for microphone voice input control / search applications on connected audio products.  

The application processor, a Quad-core ARM® Cortex-A35 MPCoreTM which includes a NEON multimedia processing engine.  

MT8516 includes two wireless connectivity functions, WLAN and Bluetooth. The RF parts of those two blocks are also built-in MT8516 chip which can support 802.11 bgn. With two advanced radio technologies integrated into one single chip, MT8516 provides the best and most convenient connectivity solution among the industry. MT8516 implements advanced and sophisticated Radio Coexistence algorithms and hardware mechanisms.  It also supports single antenna sharing among 2.4 GHz antenna for Bluetooth, WLAN. The enhanced overall quality is achieved for simultaneous voice, data, and audio transmission. The small footprint with low-power consumption greatly reduces the PCB layout resource.
