Diagnosis buffers are used for avoiding errors and discrepancies in the system in demanding applications and MEN Mikro Elektronik has developed its first device for this market.
The F218 is a slave CPU board in 3U CompactPCI format and was developed for use as an Ethernet diagnosis buffer.
It is based on the MPC8314 processor from the PowerQUICC II Pro family and offers frequencies of up to 266 MHz.
The board communicates with the system's host computer via Ethernet. The processor is connected to the CompactPCI bus via two Ethernet controllers in the FPGA, so that the host computer sees the F218 as an Ethernet device.
As the boards communicate via the backplane, a cumbersome cable connection via the front of the CPU boards is not required.
The front I/O of the slave board includes two Gigabit Ethernet interfaces, as well as a serial interface which is realized using an SA-Adapter. Optionally the onboard FPGA offers further I/O possibilities, such as additional Fast Ethernet or UARTs.
Equipped with a 256 MB DDR2 SDRAM and 16 MB flash, the board's temperature range is -40 to +85°C. It can start VxWorks in less than 2 seconds.
