Analysis of MT8516 chip technical data, introduction to MT8516 processor

Today, I will share the basic data of MediaTek's 8516 model chip processor. Here is an overview. Only some content and pictures can be extracted from some materials. If you want to do development, porting, etc., it is recommended to download the materials for reference. Discuss and communicate, and the problem will be solved.

MT8516 is a system-on-chip for Voice Assistant Devices and smart speakers launched by MediaTek in May 2017. It was released at Google I/O. The chip is the first to support Google Voice. Pre-certified System on Modules for Google Assistant and Google's IoT platform Android Things

Features: Processor: Cortex-A35, Wireless Connectivity: WiFi 802.11 b/g/n and Bluetooth 4.0, Storage: LPDDR2, LPDDR3, DDR3, DDR3L and DDR4, Interfaces: I2Sx2 (4 channels), TDM (up to 8 channels) ) and PDM input (2 channels), connected channels: USB 2.0 OTG, 10/100 Ethernet MAC, HDMI 1.4 Tx with ARC, SPDIF and embedded two-channel audio DAC and ADC.

The MT8516 platform has the industry's most advanced integrated technologies, including Wi-Fi (2.4GHz 802.11 bgn) and Bluetooth, as well as a built-in RF single-chip. This not only simplifies design and reduces time-to-market, but also reduces platform size, giving equipment manufacturers the opportunity to design their smaller, more efficient products.

There is actually a lot of information about the MediaTek MT8516. We can download the information in the U guest forum, including the processor introduction, schematic diagram, data sheet, chip solution and other reference materials:

MT8516A Processor:
MediaTek MT8516A integrates 802.11 b/g/n and Bluetooth 4.0 + HS radio and passive device (IPD)
to provide a connected audio solution. The application processor uses an efficient 64-bit Quad Cortex-A35 processor operating at 1.3 GHz. Rich memory interfaces (PCDDR3, DDR4, LPDDR3, eMMC, raw NAND) provide high level flexibility to support variant memory configurations. Well-designed MMD (MediaTek Modular Design) provides a verified schematic and PCB layout for memory and power to reduce development time. The combo chip MT6630, 802.11ac/BT also provides an alternative to meet high-end Wi-Fi/BT requirements. The MT8516A processor provides high performance computing, low power consumption and a good multimedia experience.

MT8516A integrates digital and RF based on MediaTek's world-leading SoC architecture and advanced 28nm RF process into a single chip, suitable for compact PCB design. The PMIC MT6392 is designed to serve everyone with the power of the MT8516A itself. A two-chip solution can reduce rBOM and design effort to develop applications in a fast time-to-market manner.
