Breadboardable Artix-7 FPGA Module A15T
The Digilent Cmod A7 is a small, breadboard friendly 48-pin DIP form factor board built around a Xilinx Artix-7 FPGA. The board also includes a USB-JTAG programming circuit, USB-UART bridge, clock source, Pmod host connector, SRAM, Quad-SPI Flash, and basic I/O devices. These components make it a formidable, albeit compact, a platform for digital logic circuits and MicroBlaze embedded soft-core processor designs using Xilinx's development software, Vivado. There are 44 Digital FPGA I/O signals and two FPGA Analog inputs that are routed to 100-mil-spaced through-hole pins so that you can integrate your programmable logic design directly into a solderless breadboard circuit. At just 0.7" by 2.75", it can also be loaded in a standard socket and used in embedded systems.
The only difference between the Cmod A7-15T and Cmod A7-35T are the capabilities of the FPGA found on the board. They compare as follows:
| Product Variant | Cmod A7-15T | Cmod A7-35T |
| FPGA Part | XC7A15T-1CPG236C | XC7A35T-1CPG236C |
| MSPS On-chip ADC | Yes | Yes |
| Programming options | Quad-SPI Flash/JTAG | Quad-SPI Flash/JTAG |
| Look-up Tables (LUTs) | 10,400 | 20,800 |
| Flip-Flops | 20,800 | 41,600 |
| Block RAM | 112.5 KB | 225 KB |
| Clock Management Tiles | 5 | 5 |
The Cmod A7 is fully compatible with the high-performance Vivado Design Suite. It is supported under the free WebPACK license, so designs can be implemented at no additional cost. This free license includes the ability to create MicroBlaze soft-core processor designs.
