Forlinx FET3576-C Rockchip RK3576 SoM powers feature-rich OK3576-C board for AIoT applications

Forlinx FET3576-C SoM is a new System-on-Module built around the Rockchip RK3576 SoC which features four Arm Cortex-A72 and four Cortex-A53 cores made from a 22nm lithography process. The SoM is available with 2GB or 4GB of LPDDR4 RAM option and can be equipped with up to 32GB of eMMC storage. Additionally, it has 6 TOPS NPU power and supports standard peripherals like GbE Ethernet, Wifi, Bluetooth, LVDS, MIPI DSI, and much more. All these features make this device useful for IoT, edge computing, digital signage, and many other applications.

The new FET3576-C SoM and its OK3576-C development board look very similar to the Forlinx FET3562J-C SoM and related board we covered earlier this month. But the main difference between the two is that the new one is built with the RK3576 SoC whereas the old one is built around the Rockchip RK3562(J) SoC. Previously we also saw that the RK3576 SoC was used in products like Banana Pi BPI-M5 Pro, Mekotronics R57, and others. Feel free to check those out if you are interested in those topics.

As the SoM is powered by a Rockchip RK3576 SoC, it should support OpenGL ES 1.1/2.0/3.2, OpenCL 2.0, and Vulkan 1.1. However, the company does not mention it on their products page or datasheet of the device.

In terms of software, the SoM is compatible with Linux 6.1.57 and Android and supports multi-task and multi-scenario parallel processing, as well as deep learning frameworks such as TensorFlow, Caffe, Tflite, Pytorch, Onnx NN, Android NN, and others.

The SoM also supports a new parallel bus interface which the company calls “FlexBus”. It is a flexible parallel bus interface that can emulate various protocols and support 2/4/8/16-bit data transmission with a clock speed of up to 100MHz. It offers diverse bus transfer interfaces like DSMC, CAN-FD, PCIe 2.1, SATA 3.0, USB 3.2, SAI, I2C, I3C, and UART.
