Description

ESM with Transmeta Crusoe TM5900 Simple Type: CPU Board The EM05 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 EM05, the EM05 with an application-specific carrier card and/or with additionally plugged PCI-104 modules. The EM05 is controlled by the Crusoe TM5900 microprocessor from Transmeta, a Pentium-like x86 with an integrated Northbridge that operates at 800MHz. What makes this CPU especially attractive is its extremely low power consumption of typically 5W at 800MHz and a long-term availability of five years. The EM05 is equipped with an onboard 133MHz fast DDR RAM SO-DIMM socket for data and a CompactFlash slot for scalable program storage. At its front panel the EM05 provides two RS232 interfaces and two Fast Ethernet channels via RJ45 connectors or 9-pin D-Sub connectors. Further I/O deriving from the onboard Super I/O controller such as USB, IDE, PS/2 etc. can be routed to the I/O connector of the ESM by means of an FPGA -- with the corresponding connectors available on a carrier board. In the same flexible way, additional functionality such as serial interfaces, CAN bus controllers, protocol converters, touch controller etc. can also be realized in the FPGA to the needs of the individual application. The functionality of the FPGA is dynamically loaded by the application software. The EM05 is a powerful yet low-cost industrial PC which is designed to operate in harsh environments -- an ideal solution also for infotainment applications. For a first evaluation of the functions of the EM05 it is strongly recommended to use the EK03 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)
