Time to Market for Battery Powered Products |
 |
DALLAS (Nov.
29, 1999) - Based on the industry's lowest power
embedded flash memory technology, Texas Instruments
introduced four new microcontrollers (MCUs), broadening
its |
|
MSP430
product line. The new devices allow portable/battery powered
end equipment manufacturers more flexibility by permitting
upgrades in the field and enabling more robust code
development, last minute code fixes, increased testability,
lower manufacturing costs, reduced time to market, and
non-volatile data capture.
See http://www.ti.com/sc/msds2132u
Two of the new devices are extensions of TI's MSP430C112x line
of 16-bit RISC (reduced instruction set computing) MCUs. These
flash devices, designated MSP430F112 and MSP430F1121, feature
four kilobytes (4KB) of flash memory, an operating voltage
range of 1.8V to 3.6V and 2.2V to 3.6V respectively, and up to
8 MIPs performance. The MSP430F1121 also includes a comparator
module, which enables low cost, high-precision
analog-to-digital conversion (ADC).
The other two devices, the MSP430F110 and MSP430F1101, offer a
new, low cost product line in flash-only versions, providing
the same functionality as the MSP430F112 and MSP430F1121,
except they offer a smaller 1KB flash memory at a lower price
point.... |

| Burr-Brown
Announces Quad, 16-Bit Digital-to-Analog Converter with
High-Voltage Output |
 |
TUCSON,
Ariz. (BUSINESS WIRE) December 1, 1999 Burr-Brown
Corporation (NASDAQ: BBRC) today announced |
|
the DAC7744,
a quad, 16-bit digital-to-analog converter (DAC)providing the
low power and small size needed in industrial and process
control, automatic test equipment (ATE), motor control, and
data acquisition systems.
The DAC7744 features a high-voltage output range specifically
designed for fast settling in both single supply (+15V) and
dual supply (±15V) applications. Within these systems, the
DAC7744 converts a digital signal from a microprocessor into
an analog output to precisely control a "real world"
action.
"The quad DAC7744 is the first of a new family of 16-bit
D/A converters targeted for high performance
applications," said Don Travers, product marketing
manager at Burr-Brown.
The DAC7744 features low power consumption (50mW per DAC),
fast settling time (10µs to 0.003%), unipolar or bipolar
operation, programmable reset (mid-scale or zero-scale), and
guaranteed 16-bit monotonicity over the -40°C to +85°C
temperature range. It accepts 16-bit parallel input data, has
double-buffered DAC input logic (allowing simultaneous update
of all DACs), and provides a readback mode of internal input
registers.
The DAC7744 is priced from $29.58 in 1,000 piece quantities
and packaged in a 48-lead SSOP. Delivery is from stock. |

| PREMIS™
EMI-Reducing Frequency Timing Generators |
 |
Cypress's
new PREMIS™ Frequency Timing Generators reduce EMI in
a variety of systems (from printers to video games) by
as much as 20 dB. |
They ease the
process of passing government-mandated emission testing,
speeding time-to-market.
The PREMIS
product family relies on modulating the frequency of output
signals with a low-frequency carrier to reduce EMI. This
technology enables systems to pass increasingly difficult EMI
testing without resorting to costly shielding or redesign.
Every device in the
PREMIS product line offers selectable input to output
frequency, -1.25 percent to -3.75 percent down spread output,
and integrated loop filter components. Designed in low-power
CMOS, the devices operate with either a 3.3V or 5V supply.
The W181, W183, and
W185 offer output ranges of 28-75 MHz. The W180, W182, and
W184 output frequencies ranging from 8-28 MHz. The W180 and
W181 come in 8-pin SOIC packages; the W182 and W183 are
offered in 16-pin SOICs; and the W184 and W185 come in 24-pin
SSOPs. All of the devices are available today.

Spread spectrum
transceiver controlled by PIC
In modern telecommunications spread spectrum methods are
widely present. Regardless whether it is frequency hooping
method, direct sequence method or time hooping method, these
aspects have a lot in common:
· Excellent signal/noise ratio,
· Efficient usage of radio spectrum,
· Great immunity on jamming and minimized danger of
'listening'.
Fast development of microcontrollers seeks for the usage of
these devices in modern telecommunications. This article is to
present the simplicity if a transceiver based on the spread
spectrum method of frequency hooping.

Light Dimming
Regulation |
This device regulates the light dimming. It regulates the light
intensity of standard bulbs. This is an illustration how we can
use microcontrollers in applications such as controlling the
intensity of light dimming. In this article, you also can find
out how to connect a microcontroller to an AC power line, and to
a triac. We can design the same function in a simpler way
though, using (triac, diac, couple of resistors and capacitors).
There are numbers of electrical schematics available on the net,
describing how to do this. My unit is powered directly from an
AC line. Powering from AC line enables the microcontroller to
directly trigger a triac (for example - triggering without
optotriac and similar things, which usually characterize
microcontroller and triac connection.)

Convert Analog into Digital
Challenge - Project
|
Surfing on the net,
visiting websites connected to electronics, I also visited TI. I
noticed the banner “Convert Analog to Cash – TI $60,000 Analog Design Challenge “ .
It sounded interesting to me, so I decided to find out more...and here is my
journey...
This
competition was organized by TI together with other sponsors.
The money fond for rewards was $60.000. First price was
$5.000. Many of the rewards were components, software, books,
developing tools.
This article is a description of my project, sent to TI,
entering the competition. I also provided two files, sch
and pcb. You can download them at the bottom of this article.

The Positron Brain from the

fact coming out of this. We all are surrounded by a large number
of ''devices'' whose ''behavior'' is pretty complicated and
demands ''constant monitoring of the outside world and answering
to its impulses''...
