The SMM151/2/3 family provides Digital Power Management via an I2C interface and non-volatile memory allowing the user to retrieve real-time parametric information (voltage/current) and configure power functions, such as: glitch filter duration for ignoring spurious noise signals, margin delay, margin high and low limits, GPIO power-up polarity, voltage monitoring mode (under-voltage or over-voltage) and device handling of fault conditions. The SMM151/2/3 family is supported by Summit’s easy-to-use PC-based graphical (GUI) development environment that allows system designers to digitally program the output power supply, read current and voltage information and control a variety of power management functions with a few clicks of a mouse. In high-volume production Summit provides product that is pre-programmed with the customer’s “custom configuration” at no extra cost…

Summit’s Programmable Environmental Monitor Provides Real-time Power Information and Enables Green System Designs

Real-time output voltage and input current monitoring allows for sophisticated power control, while output voltage margining maximizes system reliability

The Extensible Host Controller Interface (xHCI) draft specification provides a standardized method for USB 3.0 host controllers to communicate with the USB 3.0 software stack. The Intel xHCI draft specification revision 0.9 supports compatibility among various implementations of USB devices and will make it easier to develop software support for the industry. The Intel xHCI draft specification revision 0.9 is being made available under RAND-Z (royalty free) licensing terms to all USB 3.0 Promoter Group and contributor companies that sign an xHCI contributor agreement; information is available online from Intel Corporation…

Intel Unveils Extensible Host Controller Interface Draft Specification to Support USB 3.0 Architecture

Intel Corporation announced the availability of the Extensible Host Controller Interface (xHCI) draft specification revision 0.9 in support of the USB 3.0 architecture, also known as SuperSpeed USB. The xHCI draft specification provides a standardized method for USB 3.0 host controllers to communicate with the USB 3.0 software stack.

The TOIM5232 provides proper pulse shaping of RS-232 data signals for serial infrared (SIR) IrDA transceivers and supports data rates from 1.2kbit/s to 115.2kbit/s. Typical applications for the TOIM5232 will include wirelessly enabled data loggers and utility meters; IrDA communication in mobile phones, notebook computers, PDAs, and other consumer electronics; and medical applications such as glucose meters and home diagnostic meters. The TOIM5232 features an operating voltage range of 2.7 to 3. 6V with 5-V tolerant inputs. Maximum current consumption in standby mode is a very low 1µA. The TOIM5232 is software programmable through the RS-232 port and needs no external wiring for the baud rate setting…
