 This FPGA replacement is called
 https://www.ohwr.org/600
 
+The nanoFIP is an Actel FPGA component implementing the
+[WorldFIP](WorldFIP) protocol that can be used in field devices.
+
+The component is developed as part of the [WorldFIP insourcing
+project](https://www.ohwr.org/project/cern-fip) and is designed to be
+radiation tolerant  
+by using different single event upset mitigation techniques such as
+triple module redundancy. To improve the radiation tolerance,  
+the nanoFIP implements a minimal subset of the WorldFIP services.  
+WorldFIP variables are transferred either directly on 16-bit I/O ports
+or via a triplicated memory included in the nanoFIP component.  
+The device is used in conjunction with a [FielDrive](FielDrive) driver
+chip and [FieldTR](FieldTR) insulating transformer, both available from
+the company ALSTOM.
