MEN Mikro F206N - 3U cPCI/CompactPCI® Nios® II Slave Board

FPGA 12,000 LEs, -40 to +85°C Operation


The F206N is a 3U CompactPCI® card with an onboard Altera® Cyclone® FPGA and the integrated Nios® II soft processor. It is designed for final use in volume in an application and it acts at the same time as the standard FPGA development platform for this application.

Due to its multitude of directly accessible I/O pins the F206N can be used as a universal FPGA platform. With the Nios® II CPU inside the FPGA, the F206N can for example act as an intelligent slave on the CompactPCI® bus. In any case the F206N supports a nearly endless range of applications. Examples may include functions such as an intelligent 8-channel CAN controller with DMA and local protocol stack, real-time Ethernet controller, analog front end with DSP-like pre-computing, intelligent counter, intelligent HDLC interface etc.

The Cyclone® FPGA acts as the main controller. It supports a 32-bit/33-MHz CompactPCI® bus, controls the SDRAM memory and has read/write access to the Flash memory. The special FPGA-Flash structure provides initial programming using a boundary scan interface and later, with a configured FPGA, the device may be updated at any time with data from the CompactPCI® bus. The FPGA also controls four status LEDs and up to 79 user-defined I/O pins.

A total of 32MB soldered SDRAM and 2MB Flash back the potential computing functionality of the F206N.

The F206N is designed for use in rugged environments. For example, all components are specified for an operation temperature of -40 to +85°C.

For development of the application MEN provides a Nios® - CompactPCI® open platform FPGA development package that includes a sample design with an internal PCI system unit, integrating the standard Wishbone and the Altera® Avalon® bus.
