1 Introduction to Core Board
Chuanglong Technology SOM-TL62x is a high-performance and low-power industrial-grade core board based on TI Sitara series AM62x single/dual/quad-core ARM Cortex-A53 + single-core ARM Cortex-M4F heterogeneous multi-core processor design. Level B2B connector leads to 2x Ethernet, 9x UART, 3x CAN-FD, GPMC, 2x USB 2.0, CSI, DISPLAY and other interfaces. The main frequency of the processor ARM Cortex-A53 (64-bit) main processing unit is up to 1.4GHz, and the main frequency of ARM Cortex-M4F real-time processing unit is up to 400MHz. It adopts the latest 16nm process and has a GPMC parallel port that can communicate with FPGA at high speed. It also supports dual Different screen display, 3D graphics accelerator. The core board has been verified by professional PCB layout and high and low temperature tests. It is stable and reliable, and can meet various industrial application environments.
When users use the core board for secondary development, they only need to focus on the upper layer application, which reduces the development difficulty and time cost, and can quickly conduct product solution evaluation and technology pre-research.
