Micron Technology, Inc. recently announced qualification of the 288-Mb, reduced-latency, dynamic-random-access-memory II (RLDRAM II) products, which are now available in volume production. RLDRAM II technology's fast random access, extremely high bandwidth, and high density are optimal for high-performance networks, high-end commercial graphics, and server (L3) cache applications.

Micron's RLDRAM II technology claims to offer the best combination of bandwidth, low latency, and reduced row cycle time (t_RC) of 20 ns, thereby providing optimum bus-utilization efficiency. Additional advantages of the RLDRAM II technology feature set include on-die termination (ODT), multiplexed or non-multiplexed addressing, on-chip delay lock loop (DLL), common and separate I/O, programmable output impedance, and a power-efficient 1.8-V core. These features offer designers optimum flexibility. They provide a memory solution that is designed to fully optimize bus utilization—whether the data bus is unidirectional or has a balanced READ and WRITE ratio.

Accumet Engineering Corp. recently announced that its commitment to high customer service, continuous improvement, and technical excellence has earned it company-wide ISO 9001:2000 certification through the certification body of TUV America, Inc. ISO 9001:2000 sets standard requirements for quality assurance in business processes—from design and development to production, installation, and servicing. ISO, the International Organization for Standardization, was developed "to facilitate the international coordination and unification of industrial standards." ISO thus enhances the international trading process by providing a uniform standard of excellence. It also helps companies overcome "technical barriers to trade" through international standardization. Receiving and maintaining ISO 9001:2000 certification requires continual process improvement aimed at achieving total customer satisfaction.

The ISO standards are based on quality-management principles surrounding customer focus, system approach to management, continual improvement, mutually beneficial supplier relationships, and more. The scope of the Quality Management System at Accumet includes the lapping, polishing, diamond sawing, and laser machining of ceramics, BeO, Silca, and other dielectric substrates for a number of industries. From the time the company receives the as-fired materials from suppliers until the fabricated substrates are shipped to their final destinations, Accumet performs every operation in a way that ensures that customers consistently receive the highest-quality product.

AeroComm, Inc. now offers its ConnexLink packaged transceivers with a full Watt of output power. These transceivers can talk over distances of 20 miles line of sight. Units can be set up in minutes for cable-free communication between industrial RS-232/422/485 devices, providing reliable data transmissions of up to 115.2 kbps.

The devices' flexibility and price (under $100 per unit, which is less than half the price of similarly specified modems) suit a variety of industrial and commercial applications that include: real-time inventory and change monitoring in vending and ATMs; quick information upload to electronic signs and scoreboards; timely information retrieval on kiosks and point-of-sale displays; remote data collection from industrial loggers and monitors; communication to personal and portable PCs and handheld terminals; and printing or scanning in restaurants, grocery stores, and warehouses.

ConnexLinks are small and easily portable for use in mobile and temporary settings as well as fixed installations. They can be used as direct cable replacements, requiring no special host software for communication. Optional drivers enable custom configurations based on the user's needs.

Any number of remote ConnexLinks can be set up in point-to-point or point-to-multipoint configurations. Unique networks can be co-located on site. A unique embedded protocol (RF232) manages over-the-air concerns, such as interference rejection, error detection, addressing, security, and link verification.

ConnexLinks operating in the 900-MHz frequency band are approved for use in portable applications in the U.S., Canada, Australia, and South America. To suit the global marketplace, 2.4-GHz modems are also available. Products can be purchased from AeroComm, Avnet, Mouser, and premier distributors worldwide.

Maxim Integrated Products introduces the MAX6870/MAX6871, electrically erasable programmable read-only memory (EEPROM), hex/quad power-supply sequencers-supervisors with an integrated 10-b analog-to-digital converter (ADC). These programmable system-management devices provide design flexibility and high reliability in complex systems, such as those found in networking, telecommunications, storage, and base-station-equipment applications.

The MAX6870/MAX6871 combine voltage monitoring, supervisory functions, margining control, and sequencing control. These devices are programmed through an I²C interface that selects monitored voltage thresholds, sequence, and reset-timing specifications. It also sets output configurations. Internal-configuration EEPROM is used to store and update changes as necessary.

The MAX6870 features six voltage-detector inputs and eight programmable outputs. The MAX6871 features four voltage-detector inputs and five programmable outputs. All voltage detectors offer dual voltage thresholds in 10-mV increments for undervoltage, overvoltage, or dual undervoltage detection. These detectors can be configured to assert any of the outputs when any voltage is out of regulation.

The programmable outputs can be used to sequence supplies or provide system resets and interrupts with active-high or active-low logic. These outputs can be configured with open-drain, push-pull, and a charge-pump option (for driving external n-channel MOSFETs). There are eight available timeout periods ranging from 25 µs to 1600 ms. A margining enable input is available to set the outputs into a default (or disable) state.

An internal 8-channel, 10-b ADC reads back all the monitored voltages and two external inputs into its ADC registers. That ADC can be used to monitor voltage during margining or when trimming a power supply.

Other features of the MAX6870/MAX6871 include four general-purpose inputs, two watchdog timers, and a manual reset input. The devices are available in a 7-x-7-mm, QFN package. They are specified for operation over the extended temperature range (−40° to +85°C). Prices start at $6.39 for the MAX6870 and $5.83 for the MAX6871 (1000-up, FOB USA). An evaluation kit with a graphical user interface is available to speed designs. Visit www.maxim-ic.com for more information.
