Niestetal, Germany The CLAN7 from SMA is a ruggedized 3U CompactPCI module that combines industrial standards with a low price. Based on the LAN Controller 82551ER specifically developed by Intel for the embedded sector, this module provides an Ethernet/Fast Ethernet interface according to IEEE 802.3. In addition to the 8-pin RJ45 socket, the front panel provides a 4-pin M12 socket according to the Industrial Ethernet Standard of the IAONA organization, the industry-independent institution for industrial Ethernet. The CLAN7 is perfect for harsh environments, such as railway applications, due to the M12 socket that provides a ruggedized connection. The module can also be equipped with a rear I/O J2 connector. The configuration is easily changed by four jumpers. The CLAN7 allows data rates up to 100 MBit/s. Four LEDs in the front panel give information about the operating state of the 4 HP module as well as the quality of the LAN connection. The network is electrically separated from the system bus with an insulation resistance of 500 V DC. The CLAN7 is designed for operation in an ambient temperature range of -25° to +70°C. It is available for around $160. SMA Technologies AG , Niestetal, Germany. www.sma.de.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
