1. Development Board Introduction

• Based on Xilinx Artix-7 series FPGA processor;
• The FPGA chip model is XC7A100T-2FGG484I, NOR FLASH 256Mbit, DDR3 512M/1GByte optional, compatible with XC7A200T-2FBG484I, convenient for users to use in secondary development;
• 101K logic units, 240 DSP slices, 4 pairs of 6.6Gb/s high-speed serial transceivers, and the backplane is used as a 4-lane PCIe Gen2;
• 3 BANK voltages are configurable, providing 1.8V, 3.3V and user-defined modes, which are flexible and convenient to use;
• The core board uses a high-speed and reliable B2B connector to prevent reverse insertion and ensure signal integrity;
• PCI Express 2.0 high-speed data transmission interface, four channels, each channel communication rate can reach up to 5GBaud;
• Supports common interfaces such as PMOD, RS485, XADC, and supports Micro SD card data storage;
• The development board provides abundant I/O ports to facilitate the development and evaluation of the core board performance;
• Industrial temperature grade -40°C~85°C.

The TLA7-EasyEVM development board is a core board + baseboard development board independently developed by Guangzhou Chuanglong based on the Xilinx Artix-7 series FPGA, which can quickly evaluate the performance of FPGA. The core board size is only 70mm*50mm, and the baseboard adopts a 10-layer board design with immersion gold lead-free process. The professional PCB Layout ensures signal integrity and undergoes strict quality control to meet industrial environment applications.

The SOM-TLA7 core board leads to the rich resource signal pins of FPGA, and secondary development is extremely easy. Customers only need to focus on upper-level applications, which greatly reduces the development difficulty and time cost, allowing products to be launched quickly and seize market opportunities in a timely manner.

We not only provide a wealth of demo programs, but also provide detailed development tutorials and comprehensive technical support to assist customers in baseboard design, debugging and software development.
