Allwinner T536 octa-core RISC-V processor supports 4K video, AI acceleration, and Android/Linux OS

Allwinner Technology has recently released Allwinner T536 quad-core Arm Cortex-A55 & RISC-V industrial system-on-chip (SoC) designed for interactive terminals, smart manufacturing, and Edge AI devices that operate in harsh environments (-40°C to 85°C). It integrates four Cortex-A55 cores clocked up to 1.6GHz, a 600MHz E907 RISC-V core, and a low-power E902 RISC-V MCU for power management.

The main features of this SoC includes an optional NPU with up to 3 TOPS AI performance, ECC memory support (up to 6GB), dual Gigabit Ethernet, a PCIe 2.1/USB 3.1 DRD combo, MIPI DSI, RGB, and LVDS display interfaces, parallel and MIPI CSI camera interfaces, and various industrial I/Os like CAN FD, SPI, I2C, UART, ADCs, and PWM. It supports a range of storage options like SDIO 3.0, eMMC 5.1, SPI NOR/NAND, and raw NAND with ECC protection. The T536 also features a G2D hardware graphics accelerator, hardware ISP, and VPU supporting 4K video decoding and encoding. Security options include hardware encryption, hashing algorithms, RSA/ECC signatures, TRNG, and eFuse. Software support includes a Linux 5.10 SDK and RT-Thread 5.0 RTOS. It is available in four SKUs with different configurations of NPU and ECC memory support, making it suitable for industrial, AIoT, and embedded applications requiring high reliability, connectivity, and AI capabilities.

The T536MX series is available in four SKUs with varying NPU and ECC configurations: T536MX-CEN3 features up to 3 TOPS NPU with ECC memory support, T536MX-CEN2 offers up to 2 TOPS NPU with ECC support, T536MX-CEX includes ECC support but no NPU, and T536MX-CXX comes without NPU and ECC support.

The Allwinner products page has limited information about the T536, especially regarding software. However, MYiR Tech and Forlinx have launched system-on-modules (MYC-LT536 and FET536-C) and development boards with a Linux 5.10 SDK, though it’s not publicly available. Linux 5.10 will be supported until December 2026. RT-Thread 5.0 RTOS also supports the T536, likely running on the 600 MHz E907 RISC-V core.
