Description

ESM with PowerPC MPC 8245 Simple Type: CPU Board The EM04 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 EM04, the EM04 with an application-specific carrier card and/or with additionally plugged PCI-104 modules. The EM04 is controlled by an MPC8245 PowerPC (Kahlua II) microprocessor which operates at 266MHz up to 400MHz. The MPC8245 includes a Floating Point Unit and a Memory Management Unit. The EM04 has an SO-DIMM socket for data and a CompactFlash slot for program storage. At its front panel the EM04 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 onboard FPGA. Physical interfaces for such functions must be implemented on the carrier board. The EM04 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 EM04 it is strongly recommended to use the EK02 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. Download the datasheet (PDF)
