O’Neill Europe - a leading provider of high-quality sportswear
and sports gear - unveiled the result of a joint product development project
with Infineon: their first ‘wearable electronics’-product. Based on O’Neill’s
specifications, Infineon has developed a chip module suitable for integration
into a pioneering snowboard jacket. Adapted to withstand rough snowboarding
environments, functions such as “mobile telephony by Bluetooth” and “MP3 player”
are integrated into the sportswear. The outstanding innovation from O’Neill’s
2004/05 winter collection for the technologically clued-in snowboarder is named
Woven into THE HUB snowboard jacket are electrically
conductive fabric tracks which connect the chip module to a fabric keyboard and
built-in speakers in the helmet. The chip module contains a full-featured MP3
player and a Bluetooth module via which the snowboarder can control a mobile
phone. If the snowboarder wants to make a phone call, the stereo system acts as
the headset. The microphone is integrated in the collar of the jacket.
Recent studies by the Venture Development Corporation predict worldwide sales
worth over 1 billion Euros for the “intelligent textile materials” market by
2007. Since presenting its technology Infineon has discussed firm projects with
more than 200 companies from the textile industry. In cooperation with the
Vorwerk Teppichwerke carpet plant in Hameln, Germany, Infineon is currently
working on an initial prototype of a “smart carpet”.
Unfortunately, the Infineon press release did not go into
details by when we can expect the next generation after the smart carpet, which
would be the "flying carpet". (Our apologies to Infineon, we simply couldn't
resist on that one) ;-)

Oxford launched a dedicated FireWire audio controller IC based
on an ARM7TDMI core. Compatible with FireWire 400 (IEEE1394A) and FireWire 800
(IEEE1394B) connections, the OXFW970 chip provides eight digital audio output
channels. The OXFW970 uses the bandwidth and quality of service attributes of
FireWire to overcome the limitations of alternative USB multi-channel audio
solutions, thus enabling the creation of high quality surround sound systems.
The FireWire audio controller can receive and process 32-bit
audio data sampled at up to 48 kHz at a streaming speed of up to 100 MB/s.
FireWire's power carrying capability also means that the speaker configuration
does not require the use of external power supplies.
A highly integrated device in a 100-pin TQFP package, the
FireWire audio controller IC uses a combination of its on-board ARM7TDMI
processor and high performance buffer manager to implement the 1394 transaction
layer. Its link controller complies with IEEE1394-1995, 1394a and 1394b
specifications. The OXFW970 supports remote programming of 512 Kb of on-board
flash memory over the FireWire bus using firmware and flash programming
utilities supplied by Oxford Semiconductor. Integral UART and JTAG ports
facilitate debugging. The chip offers eight programmable GPIO pins for the
addition of application specific functionality.
Compared to conventional 0.18 μm EEPROM technology which today
achieves a typical cell size of 5 μm2, the cell size of Philips’ new
embedded EEPROM cell is only 1.2 μm2 – four times smaller than the
conventional EEPROM technology used in the industry.
Philips’ new byte-alterable EEPROM technology provides both
high density and low power consumption, while at the same time being fully
compatible with the company’s existing embedded Flash memory technology to allow
mixed Flash/EEPROM systems. Philips’ new CMOS18 EEPROM memory option is
available for design in now and is supported by all the company’s CMOS18 design
tools, including the provision of memory test facilities through a standard JTAG
The H8/38086F is the first Renesas microcontroller to
incorporate a 2 channel delta sigma type 14-bit A/D converter. At ±274 µV (typ.),
the nonlinear characteristic error with a 3.0 V full-scale range has been
improved in this A/D converter by a factor of approximately 30 compared with the
±7.3 mV (typ.) of a conventional successive approximation type A/D converter
with 10-bit resolution. The delta sigma A/D converter features an operating
voltage range of 2.2 V to 3.6 V and a conversion time of 64.1 to 1282 µs.
Peripheral functions such as a programmable gain amplifier and reference voltage
band-gap reference circuit are also provided, enabling highly accurate A/D
conversion to be achieved easily using only an H8/38086F.
Eight versatile power-down modes are also provided, enabling
low power consumption by selecting the mode best suited to device operation.
Power consumption is a low 900 µA (typ.) at 1.8 V/1 MHz operation, and ultra-low
current dissipation of 0.5 µA (typ.) can be achieved in watch mode, in which
only the watch function is active.
Other on-chip peripheral functions include 48 Kbytes Flash
memory, 2 Kbytes RAM, 2x USARTs, 16-bit output compare timer, 16-bit timer pulse
unit, 3 channel 10-bit successive approximation A/D, an LCD
controller/driver with a built-in 3 V constant-voltage circuit for display use,
a real-time clock, and an I2C bus.
