MT8516

Highly integrated, application processing platform for Cloud-connected voice assistant devices with Google Cast and PowerAQ

MT8516

The MT8516 is an efficient and highly integrated application processing platform with diverse interfaces and connectivity that focuses on audio and microphone processing. It is designed for Cloud-supported voice assistant devices, Google Cast for Audio and products with MediaTek PowerAQ infused.

MediaTek’s unique PowerAQ tool provides an easy GUI interface for signal flow design and audio parameter tuning, removing the need for an additional DSP.

MT8516 integrates a quad-core, 64-bit ARM® Cortex-A35 MPCoreTM operating at up to 1.3 GHz. In addition to raw NAND support, it has extremely flexible memory support including LPDDR2, LPDDR3, DDR3, DDR3L and DDR4 to accommodate diverse platform needs.

An extensive set of interfaces, such as I2Sx2 (4 channels), TDM (up to 8 channels) and PDM inputs (2 channels) are included for microphone voice input control and connected audio products. Connectivity includes 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 integration with both Wi-Fi (2.4GHz, 802.11 bgn) and Bluetooth, with RF built in, on a single chip. This not only provides design simplicity, reducing time to market, but also reduces the platform size allowing ever smaller, more efficient product design opportunities.
