Forlinx FET3562J-C SoM features Rockchip RK3562(J) SoC with 1 TOPS NPU, dual Ethernet, camera, display interfaces

The Forlinx FET3562J-C is a Rockchip RK3562/RK3562J powered System-on-Module (SoM) built with a 22nm process and features four high-performance ARM Cortex-A53 cores running at up to 2GHz. It also can support up to 2GB LPDDR4 RAM and can be configured with up to 16GB eMMC storage. Additionally, it has 1 TOPS NPU and standard peripherals like Ethernet, Wifi, Bluetooth, LVDS, MIPI DSI, and much more. All these features make this SoM useful for IoT, automation, and consumer electronic applications.

Previously, we have seen Forlinx launch similar SoM with development boards such as the Forlinx RZ/G2L, the FET-MX9352-C, the OK335xS-II and much more feel free to check those out if you are interested in the topic.

Th company mentions that the SoM can be configured with RK3562J or the RK3562 SoC, the RK3562 offers faster processing speeds with its 2.0GHz ARM Cortex-A53 cores and 1 TOPS NPU, while RK3562J’s cores are clocked at up to 1.8GHz so that it can operate reliably in a wide -40 to +85°C temperature range, and does not include an NPU.

The SoM has support for OpenGL ES 1.1/2.0/3.2, OpenCL 2.0, and Vulkan 1.1 for graphics and compute acceleration, along with a dedicated 2D hardware engine. It also includes a high-quality JPEG encoder and decoder and supports LVDS, MIPI DSI, and RGB display interfaces. The processor is also compatible with TensorFlow, MXNet, PyTorch, and Caffe AI frameworks, making it easy to convert and deploy machine learning models. The company only provides limited public software information such as support for Linux 5.10.198 with Qt 5.15, Android (TBD), and AMP (TBD), but customers will get hardware-related documentation such as a datasheet, a user guide, carrier board schematics, carrier board PCB layout, and SoM pinmux, and software resources including OS image, testing demo, source code, manual, and compiling environment.

The company has not released any pricing information for the Forlinx FET3562J-C SoM. More information about the Rockchip RK3562(J) system-on-module and associated development board can be found on the product page.
