2-Mbit MRAMs for Automotive (Freescale)
Freescale’s MRAM family consists of 2-Mbit devices with a choice of commercial-, industrial- and extended-temperature ranges (operating from -40 to +105°C). The extended-temperature version is suitable for use in rugged-application environments, such as military, aerospace and automotive designs.

FlexRay Rapid Prototyping Module (ETAS)
With the launch of the ES910 rapid-prototyping modules, ETAS provides a new-generation compact module for in-vehicle rapid-prototyping applications. The ES910.2 module can be extended by adding the ES920.1 FlexRay module, which is connected to the PC through a Gbit/s Ethernet interface.

Enhanced 4-Channel LIN Trans (Melexis)
The MLX80001 combines four LIN transceivers on one die and enables the development of simpler and more cost-effective multi-LIN network-master modules. Integrated LIN master-termination resistors and decoupling diodes further reduce system costs.

Software-Design Choices for Multimedia Devices
What song was I listening to the last time I drove my car? Can I hear more songs like the one now playing? Can I pause this live radio broadcast and listen to the rest of it later? Can this car audio system rip CDs to a hard drive while playing songs stored on my iPod? Whether today’s consumers are relaxing at home, driving to work, or jogging in the park, they have come to expect a highly personalised media experience. Randy Martin from QNX shows in his article how a RTOS supplier can help to realise personalised multimedia.

Verifying Serial-Data Designs Using Physical-Layer Scans
New waveform-scanning techniques developed during the past year have made the task of troubleshooting automotive-serial-data designs systematic and precise. This article by Mike Hertz from LeCroy focuses on several powerful techniques for the rapid characterisation and debug of automotive signaling.

Microcontroller Drives LCD with just one Wire
D44780 LCDs are the most popular alphanumeric displays in embedded systems. The only downside is that they use six I/O pins in 4-bit nibble mode and as many as 11 pins in 8-bit mode. Earlier Design Ideas have described many approaches to saving or expanding I/O pins. The circuit in the Design Idea by Noureddine Benabadji from the University of Sciences and Technology in Oran, Algeria, proves useful for any pin limited embedded system that must interface with an HD44780-compatible display through a one-wire serial link using an asynchronous, simplified RS-232 protocol at 9600 baud.

Circuits Monitor and Balance Large Lithium-Ion Batteries
When using rechargeable lithium- ion cells in large batteries, such as those in an electric vehicle, you encounter unique problems. This Design Idea by Daniel Gomez-Ibanez from the Woods Hole Oceanographic Institution in Woods Hole, Massachussetts, provides one strategy for protecting and balancing large, high-voltage batteries.

Ultrawideband Beginning To Take Off
The market for Ultrawideband (UWB) silicon is finally beginning to take off in 2007, reports In-Stat. Though regulatory hurdles over UWB still persist worldwide, the first UWB-enabled notebook PCs have shipped this year from Dell, Lenovo, and Toshiba. The primary question for UWB now is: Will other product segments follow where PCs lead? UWB is a very flexible technology in that it supports multiple standards, including WUSB, Bluetooth 3.0, IP over UWB, and Video over UWB.

RF Circuit Design, Second Edition, by Christopher Bowick et al.
RF circuit design is now more important than ever as we find ourselves in an increasingly wireless world. Radio is the backbone of today’s wireless industry with protocols such as Bluetooth, Wi-Fi, WiMax, and ZigBee. Most, if not all, mobile devices have an RF component and this book tells the reader how to design and integrate that component in a very practical fashion. This book has been updated to include today's integrated circuit (IC) and system-level design issues as well as keeping its classic "wire lead" material.
