Analogue MCU (Silicon Laboratories)
The C8051F52/3x family of highly integrated analogue MCUs is
designed specifically for automotive electronics, and leverages
manufacturer Silicon Laboratories' track-record in designing
mixed-signal devices with very small footprints.

Galileo-Ready Receiver IC (SiGe Semiconductor)
SiGe
has released what it claims is the world's first Galileo-ready
receiver. The device targets mass-market consumer electronics and is
expected to enable the integration of high-accuracy navigation
services into portable devices such as laptop computers, PDAs,
phones, and cameras.

GPS
Baseband IC (U-Blox)
The
ATR0625 GPS baseband IC ships with u-blox' SuperSense GPS
weak-signal tracking software included in its ROM. The chip is based
on the Antaris4 developed for automotive, handheld and mobile
applications.

Cargo
Management (Wi-Fi Wireless)
The
WFSCT System from Wi-Fi Wireless allows shipping companies benefit
from a technology that facilitates cargo tracking and monitoring
on their vessels without expensive or complicated ship-board
installations.

Collecting Accurate Field Data in Motorsport
Limited testing and tighter regulations mean that race engineers
are increasingly relying on data acquisition throughout the
vehicle to maximize performance. Advanced computer modelling can
provide some of the answers but collecting accurate data in the
tight confines and harsh conditions of motorsport is difficult,
especially when accuracy can be safety-critical. John Bailey
from Beru F1 Systems describes a solution in his article in EPN.

LGA
Capacitors: A New Design for Low-Inductance Decoupling
Decoupling capacitors are widely used to minimise supply-voltage
fluctuations. Many strategies have been employed to lower the
inductance of these devices, thereby improving their frequency
response. The new LGA (Land Grid Array) capacitor from AVX, which is
described in detail in Andy RitterŽs article in EPN employs a
precision termination process to produce a device that combines low
ESL (Equivalent Series Inductance) with a simple, two-terminal
construction

PIC
microprocessor drives 20-LED dot- or bar-graph display
The
circuit described by Noureddine Benabadjj from the
University of Sciences and Technology,
Oran, Algeria
in his Design Idea uses only five I/O lines to drive a dot or
bar-graph display of 20 LEDs. Although this version of the design
uses a small and inexpensive one-time programmable microprocessor,
such as a Microchip PIC12C508A, you can use other microprocessors
with N I/O lines to drive multiple LEDs.

Bipolar current source maintains high output
impedance at high frequencies
Traditional current sources and voltage-to-current
converters based on instrumentation and operational amplifiers offer
high output impedances at low frequencies because of the amplifiers'
good low-frequency CMRR (common-mode-rejection ratios). At higher
frequencies, decreasing CMRR, inherent output capacitances, and
slew-rate limitations prevent realization of high-quality current
sources.
Alex Birkett from the University College London, Hospital National
Health Service, London, UK shows in his Design Idea in EDN how to
overcome that problem.

Auto Electronics Market Set to Exceed US$50
Billion by 2010
The world market for non-entertainment automotive electronics
was estimated at US$36.8 billion in 2005 and is forecast to
reach US$52.1 billion by 2010, according to the latest figures
from a report published by Reed Electronics Research and
distributed by In-Stat. Growth is forecast across all product
segments and regions with the strongest demand coming from the
emerging markets in Asia and East and Central Europe. North
America will show an average increase of 5.1% per year in the
period to 2010, with the market increasing from US$13.2 billion
in 2005 to reach US$16.9 billion in 2010. Although North America
is a mature market for a number of automotive electronic
systems, strong growth will be seen for electronic braking,
steering and driver information.
