SOPHGO SG2000 and SG2002 are new SoCs featuring a bunch of RISC-V and Arm cores capable of running Linux, Android, and FreeRTOS simultaneously, and to maximize the fun an 8051 MCU core is also in the mix along with a 0.5 TOPS (SG2000) or 1 TOPS (SG2002) AI accelerator.
More specifically we have one 1GHz C906 64-bit core capable of running Linux, one 1GHz Arm Cortex-A53 for Linux or Android, another 700 MHz C906 RISC-V core for FreeRTOS, and a 300 MHz 8051-core for real-time I/Os, as well as 256MB or 512MB SiP DRAM. The chip is designed for AIoT applications such as Smart IP cameras, facial recognition, and smart home devices.

We previously covered other higher-end RISC-V processors from SOPHGO with the 16-core SOPHGO SG2380 and the 64-core SG2042 found in the Pioneer RISC-V motherboard and workstation, while the new SG2000x are entry-level chips.
A Linux-5.10-based SDK is said to be available for the chip, but software resources don’t seem available right now, although the diagram below shows a bit of what to expect, including Arduino support for the 700MHz RISC-V core. The 512MB RAM will be really tight to run Android, Linux, and FreeRTOS… The technical reference manual (TRM) and hardware design documentation are available on the product page, but only in Chinese at this time.
At least three SBCs based on SG2000/SG2002 are in the works with Shenzhen MilkV Technology’s Duo S (SG2000) and Duo 256M (SG2002), and Sipeed’s LicheeRV Nano (SG2002). We’ll cover those in more detail once they become available.
[Update: I’ve just seen the LicheeRV Nano is already available for sale on Aliexpress with either Ethernet or WiFi 6, a Linux repo can be found on GitHub, as well as some documentation. I’ll check that in more detail soon…]
