Allwinner T536 quad-core Arm Cortex-A55 & RISC-V industrial SoC supports ECC RAM, up to 3 TOP AI accelerator

Allwinner T536 SoC features four Cortex-A55 cores, a 600 MHz RISC-V core, and a low-power RISC-V for power management, as well as support for ECC memory and an optional NPU with up to 3 TOPS of AI performance.

The processor is designed to work in the industrial temperature range (-40 to +85°C) and offers plenty of I/Os, including two Gigabit Ethernet, a USB 3.1 DRD and PCIe Gen2 conbo, MIPI DSI, RGB, and LVDS display interfaces, paralle CSI and MIPI CSI camera interfaces, CAN FD, SPI, I2C, UART, several ADC, and more. The SoC is designed for interactive terminals, smart manufacturing, and other Edge AI industrial equipment.

The product page on the Allwinner website has limited details, and I found most of the information in the product brief shared on a Russian website. There’s no information about software there, but MYiR Tech and Forlinx have already launched two Allwinner T536 system-on-modules with the MYC-LT536 and FET536-C and their respective development boards.

That means we have (some) details about the software. Both companies provide a Linux 5.10 SDK with all drivers, but it’s not made publicly available. As a side note, Linux 5.10 was released in December 2020, and it’s scheduled to be supported until December 2026. RT-Thread 5.0 RTOS also supports the Allwinner T536 (first GitHub repository from Forlinx), and I assume it’s running on the 600 MHz E907 RISC-V core rather than the Cortex-A55 cores.
