Description
Small is beautiful! If you're seeking for the smallest FPGA modules available with Xilinx FPGAs, then "Zefant-nano" will be your choice. The modules are shrinked to the absolute minimum footprint while not ranking behind other modules in any aspect.
Besides a Spartan-3E with 500k or 1.2M system gates, the module contains 128MBit flash memory and 128MBit PSRAM, a Coolrunner CPLD, an efficient SMPS with wide input voltage range (4...25V!) and more hardware on a footprint of only 30x37mm (1.18 x 1.46") and 39x37mm!

Like the other Zefant modules, Zefant-nano is stackable. It's available in two versions with one or two board-to-board connectors.

- Stamp sized - extremely small footprint
- Spartan-3E based
- 128MBit onboard PSRAM
- 128MBit onboard Flash Memory
