Allwinner A133 tablet processor pairs with XR829 or AW859A WiFi & Bluetooth chip

Last year, Allwinner published an updated roadmap for tablet processors that included A100, A200, and A300 SoC’s. None of those have been launched yet, but I’ve just noticed the Allwinner A133 quad-core Cortex-A53 processor showed up on the company’s website.

That’s yet another entry-level processor coupled with a PowerVR GE8300 GPU, but you’d get support for Android 10, instead of the older Android 7.1/8.1 SDK provided for the earlier Allwinner A-series tablet processors. This time around, the company also pairs A133 processor with its own wireless chips, either XR829 WiFI 4 and Bluetooth 4.2 chip, or AW859A dual-band 802.11ac WiFi 5 and Bluetooth 5 chip.

It appears the company is now attempting to provide a complete solution mostly comprised of their chips with the main processor (A133), XR829 or AW859A wireless chip/module, and AXP707 PMIC. AW859A WiFi Bluetooth ModuleSometimes I’ve seen the Allwinner-branded memory as well. That means we may see less Allwinner hardware with Ampak wireless module going forward.

AW859A is already used in some Allwinner H616 designs including X96Q MAX TV box, and Shenzhen Xunlong will soon launch an updated version of Orange Pi Zero2 SBC with Allwinner H616 and AW859A module.

Additional details can be found on Allwinner A-series product page. I could not find information about AW859A module, but firmware files can be found on Orange Pi Xunlong’s github repository. XR829 is a bit older and has its own product page on XRadioTech website.
