The LP39798 is offered in a 12-pin WSON package with thermal pad and is price at $1.30.
PICMG introduced a new revision and upgrade to the CompactPCI Express specification, Revision 2. This revision of CompactPCI Express features interoperability at both the interface and product level, and increase performance. The latest specification will allow rapid adoption in instrumentation and control applications where performance and interoperability are critical. The PXI standard, which currently builds on top of CompactPCI and CompactPCI Express, will see immediate benefit from the new revision.
ASSET InterTech published an ebook about JTAG. The article describes how the structural test methodology based on the IEEE 1149.1 boundary scan standard can apply functional tests to I2C and SPI system monitors during prototype board bring-up and later during production of the circuit board. The title of the technical paper is: Functional Test on I2C and SPI System Monitors with JTAG.
Cadence Design Systems plans to acquire the IP business of Evatronix SA SKA. The acquisition is expected to close in the second quarter of 2013, and is not expected to have a material impact on Cadence’s balance sheet or second quarter or fiscal 2013 results of operations. Terms of the transaction were not disclosed.
Oven Industries announced the 5R7-388 RoHS compliant controller. Model 5R7-388 is a bi-directional electronic temperature controller for independent thermoelectric modules or in conjunction with auxiliary or supplemental resistive heaters for both cooling and heating applications. The H bridge configuration of the solid state MOSFET output devices allows for the bi-directional flow of current through the thermoelectric modules. Highly efficient N-channel output devices are used for this control mode. The 5R7-388 is priced at $369.
Texas Instruments announced the TCA8424 human interface device (HID) over I2C, 128-key keyboard controller and SN65DSI85 digital serial interface (DSI) to FlatLink interface IC. The TI TCA8424 is available in a 6mm by 6mm by 1mm 40-pin VQFN package. It is priced at $0.80 in 1,000-unit quantities. The SN65DSI85 is available in a 5mm by 5mm by 1mm, 64-ball PBGA package. Prices start at $3.90 in 1,000-unit quantities.
Microchip Technology introduced the LIN 2.1 and SAE J2602-2 compliant and low-power MCP2003A transceiver, MCP2021A, MCP2022A, MCP2025 and MCP2050 LIN System Basis Chips (SBCs), and PIC16F1829LIN System in Package (SiP). The devices feature a voltage regulator, windowed watchdog timer, battery monitor output, MCU, high Electromagnetic Compatibility (EMC) and Electrostatic Discharge (ESD) levels of more than 15 kV on the LIN bus and battery-voltage pins.
Oven Industries introduced the 5R7-001 Temperature Controller. The 5R7-001 serves as the commander of thermoelectric modules. It creates a seamless transition between heating and cooling devices. The RoHS compliant 5R7-001 features a load current of .1 to 25 Amps, temperature range of -40 to 250 degrees Celsius, large program memory space, PC programmable, 0-36 VDC output, and a split power supply system.
Texas Instruments announced the TPS92660 two-string LED driver and TPS92640/1 synchronous buck controllers. The three TI DC/DC LED drivers simplify white color tuning for high-color rendering and ultra-low dimming in professional-grade indoor and outdoor LED lighting applications. The TPS92660, TPS92640 and TPS92641 are available in volume now. The TPS92660 is available in a 20-pin PowerPad TSSOP. It is priced at $1.50 each in 1,000-unit quantities. The TPS92640 is offered in a 14-pin PowerPad TSSOP and the TPS92641 is offered in a 16-pin PowerPad TSSOP. The devices are priced at $1.75 and $1.85, respectively.
According to a new white paper, the interplay between the effects of statistical reliability and variability could adversely affect 20nm CMOS SRAM yield. The study also defined a new reliability simulation framework to predict variability and reliability impact that enhances yield. The article was published by Gold Standard Simulations (GSS) and the University of Glasgow Device Modelling Group at the International Physics Reliability Symposium in Monterey, CA.
