15EM04N01 (MEN MIKRO)

The EM4N is a complete embedded single-board computer for use on any carrier board in different industrial environments. The final application consists either of a stand-alone EM4N, the EM4N with an application-specific carrier card and/or with additionally plugged PCI-104 modules. The EM4N is controlled by an MPC8245 PowerPC microprocessor which operates at 266 MHz up to 400MHz. The MPC8245 includes a Floating Point Unit and a Memory Management Unit. The EM4N has an SO-DIMM socket for data and a CompactFlash slot for program storage.At its front panel the EM4N provides two RS232 interfaces and two Fast Ethernet channels. Additionally, nearly unlimited I/O functionality such as graphics controllers, serial interfaces, CAN bus controller etc. can be realized in a very flexible and cost-effective way by means of an on-board FPGA. Physical interfaces for such functions must be implemented on the carrier board. Compared to the EM4, the EM4N is equipped with a larger on-board FPGA, which has a capacity of 12,000 logic elements. The EM4N 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. The EM4N is an ideal computer for low-cost deeply embedded solutions in very harsh environments, for machine control, Man-Machine Interfaces, field bus bridges or embedded Linux PCs. For a first evaluation of the functions of the EM4N it is strongly recommended to use the EK2 ESM starter kit. The kit consists of the standard CPU module, an FPGA loaded with additional I/O functions, the carrier card with I/O connectors, an external PSU, VGA and RJ45 to D-Sub cables, and an adapter for mounting a PCI-104 module. ESM modules are complete computers on a plug-on module. They consist of the hardware (CPU, chip set, memory, I/O) which is not fixed to any application-specific function, and an FPGA programmed in VHDL code, which provides I/O that is also still independent of a specific application. ESM™ modules are based on PCI. They have two system connectors: J1 has a fixed signal assignment, while J2 is variable depending on the final application-specific configuration of the ESM and the carrier board. J2 also feeds the I/O signals of the functions programmed in the FPGA to the carrier card.
