Frequently Asked Questions
Q1: What are the main computing and AI specifications of Amlogic A311D2 SoC?
A: A311D2 is octa‑core SoC with 4×Cortex‑A73 + 4×Cortex‑A53 CPU and Mali‑G52 MP8 GPU. Native NPU performance is 3.2 TOPS. It reaches 5 TOPS with extra software license.
Q2: What video and display capabilities does A311D2 support?
A: It supports hardware 8K@24fps decode and 4K@50fps encode. It has 3‑channel HDMI2.1 input, and multiple display outputs: HDMI2.1, MIPI‑DSI, LVDS, V‑by‑One, eDP for multi‑screen solutions.
Q3: What is the difference between A311D2 and A311D? Are they pin‑to‑pin compatible?
A: A311D is the predecessor. A311D uses 4×A73+2×A53, max 4GB 32‑bit memory and no HDMI input. A311D2 upgrades CPU, 64‑bit bus up to 16GB RAM, adds 3×HDMI2.1 input and higher‑spec GPU. They are NOT pin‑to‑pin compatible, PCB redesign is required.
Q4: What alternative SoC options for A311D2?
A: Rockchip RK3588 for higher NPU performance. A311D for cost‑sensitive projects without HDMI‑input requirement. There is no direct drop‑in pin‑compatible replacement.
Q5: Is A311D2 an industrial‑grade chip?
A: No. It is extended commercial grade, operating temperature ‑20℃ ~ +70℃. Do not use for long‑term industrial harsh‑temperature scenarios.
Q6: How to get A311D2 datasheet, SDK and EVB information?
A: Submit inquiry form to obtain datasheet, SDK documents, EVB details and bulk quotation.
Q7: Is the 5 TOPS NPU performance enabled by default?
A: No. Default NPU performance is 3.2 TOPS. 5 TOPS high‑performance mode requires official license authorization.
