OVERVIEW
A31 is a highly integrated mobile application processor designed to provide high performance solutions for
tablets, handsets, and smart TVs, etc.
It comes with a Quad-core Cortex-A7 CPU architecture that allows outstanding computing capability with
less power consumption, a powerful SGX544 GPU with eight logic cores, and a robust multimedia
processing system that capable of 4Kx2K video decoding, Blu-ray 3D and perfect compatibility for stream
media, etc.
A31 also features dual-channel 32bitx2 DRAM bus to provide wider bandwidth, and dual-channel NAND
flash to speed up Read/Write operations.
Besides, A31 provides a board range of peripheral interfaces. For example, it comes with display interfaces
such as HDMI, LCD RGB, MIPI DSI, and LVDS, image input interfaces such as CSI and MIPI CSI, and data
interfaces such as USB DRD, USB EHCI/OHCI, GB Ethernet, SDC, SDIO, etc.
When it comes to power efficiency, A31 features smart Power Consumption Management System to
dynamically adjust CPU frequency and voltage, DRAM Dynamic Frequency Scaling technology to
dynamically adjust DRAM frequency based on bandwidth requirements, and also supports Super Standby
Mode to lower the power consumption during system standby.
