A14C - MPC8540 CPU Board (Product Discontinued)

The A14C is an advanced PowerPC based single-board computer for embedded applications. It features full VME64 support and it can be used as a master or a slave in a VMEbus environment. The CPU card provides 1 MB local shared SRAM for slave access and communication between the local CPU and another VMEbus master.

The A14C is controlled by an MPC8540 integrated PowerPC processor working at 800 MHz. The SBC is equipped with a DDR SO-DIMM socket for data storage, with NAND Flash for program storage as well as with non-volatile FRAM. The board provides front-panel access for two Gigabit Ethernet, one fast Ethernet and one COM via four RJ45 connectors. Four more UARTs are optionally accessible via SA-Adapters for front connection.

Additional functionality such as graphics, touch, CAN, binary I/O etc. can be realized as IP cores in FPGA for the needs of the individual application. The corresponding PHYs are available via SA-Adapters on a transition module to the rear.

The FPGA acts as a standard PCI device on the A14C. The FPGA functions are loaded by software during power-up within less than 1s. FPGA updates can be carried out dynamically during operation.

In addition, the A14C can be equipped with PMC mezzanine cards supporting 64 bits/66 MHz as well as front I/O and rear I/O (PIM).

The A14C comes with MENMON support. This firmware/BIOS can be used for bootstrapping operating systems (from disk, Flash or network), for hardware testing, or for debugging applications without running any operating system.
