3/10/2003 - The Swiss company DIGITAL-LOGIC AG, one of the world's leading companies in the embedded computer market, presents the smartModule SM520PC/PCX, a new PC module according to the PC/480 standard. The compact embedded PC is based on an ELAN520 microcontroller, which has been proved as a stable and high-performance CPU. All peripherie and bus interfaces including USB, VGA and optional Ethernet are combined on a single bus, the smart480Bus, and can be integrated into a customer-specific environment. Thanks to the low power consumption of typically 7 W, the module does not require active cooling and operates within a wide temperature range of ˇV40˘XC to +85˘XC. The SM520PC/PCX is a cost-effective solution for all industrial and medical applications for which DOS, Linux or Microsoft's embedded operating systems are sufficient control units.
The smartModule SM520PC/PCX is remarkable for its small dimensions of 66 mm x 85 mm, and its flat, low profile design, at only 14 mm. It works at a clock frequency of up to 133 MHz, and has a large main memory, which can be mounted individually with SODIMM components from 16 MB to 128 MB DRAM. Also integrated are a boot-capable flash disk with capacities of from 2 MB to 8 MB; two USB (Universal Serial Bus) interfaces and an optional LAN interface (82559ER).
The PC module is equipped with an SXGA-69000 video controller, 2 MB video RAM, and a 36-bit LCD interface, and offers resolutions of up to 1280 x 1024 pixels with 256 colours. The standard version further includes interfaces for hard disk, floppy disk, keyboard, mouse, printer, and TTL ports at COM1 and COM2. Further technical features are a watchdog, a connection for an external RTC battery, EEPROM support up to 1024 bytes, and support of external IrDA ports. The SM520PC/PCX requires a 5V power supply and runs under Windows„µ CE/98/NT4 and Linux. An MTBF (mean time between failure) value of over 200,000 hours confirms the high level of reliability and longevity of the PC.
Innovative Modular Concept
The smartModules from Digital-Logic are multi-chip modules, which encapsulate the entire functionality of a PC. All signals, common interfaces, ISA and PCI bus are combined on a single bus, the smart480Bus, and are integrated in the customer-specific environment via two connectors with a total of 480 contacts. At the same time the smartBus serves as the technology interface, so future smartModules will continue to be mechanically, electrically and functionally compatible. The innovative concept of the smartModules makes the integration of an embedded PC in an individual, PC-based application simple, fast and cheap. smartModules are an easily exchangable, scalable, future-oriented alternative to the direct implementation of the entire PC electronics in a customer design. The modular concept also reduces the risks involved in developing customer-specific designs. The developers of individual series devices thus become more independent of the modification cycles of the PC hardware. They can integrate future process technologies in their applications without major changes, and offer need-oriented families of devices with varied processor power. Only the carrier board still has to be developed specifically for the application.
The use of the smartModule PCs as optimised, tested components in the development of new products and therefore not only reduces the design effort and the development costs, but also can drastically reduce time-to-market. Even in small numbers, the smartModules offer optimum price/performance. They are also the ideal solution whenever customer-specific electronics are necessary or specified, and the available space and ambient conditions do not permit an embedded PC board to be used.
