A few months ago we released the Arty S7 and only had the Arty S7-50 available. Today, we are introducing the Arty S7-25, the lowest cost Arty board to date.
To recap, the Arty S7 products are Arty-form factor boards built around Xilinx’s cost-optimized, Spartan 7 FPGA family. The Spartan 7 family was released to give engineers access to high-class performance, high cost per watt ratios and with small form factor packaging options. The technology is on the 28nm processes, vs the older, slower 45nm technology that Spartan 6 is. Fully supported in Vivado, the Spartan 7 FPGA is ideal for engineers who enjoyed the applications of the Spartan 6, but want to use a more up-to-date technology and toolchain.
The Arty S7 comes in two varieties. They are identical, except for the FPGA on board, which differs in the following table:
|Variant||Arty S7-25||Arty S7-50|
|1 MSPS On-chip ADC||Yes||Yes|
|Block RAM (Kbits)||1,620||2,700|
|Clock Management Tiles||3||5|
|Internal Clock Speed||450MHz +|
|On board ADC||Yes (XADC)|
|Programmable over JTAG/QSPI||Yes|
If you are curious about what an Arty S7 can do, check out the Element 14 Road Test and the Arty S7 Pmod Pack. Both of these should be compatible with the Arty S7-25, but if there are any questions about migration, we encourage you to visit the Digilent forum.
We are excited about the addition of the Arty S7-25 and can’t wait to see what designs it enables!
