Part of a family of ultra-low power, real-time clocks (RTCs), the
EM3027 is reportedly the first RTC with compensated frequency deviation
over temperatures from -40°C to +125°C and a temperature sensor with
digital readout capability. The clock operates from a supply voltage of
1.3V to 5.5V and its power-management unit automatically detects any
supply interruption. An integrated switchover function connects the RTC
part to the backup power supply to ensure full data integrity.
Additionally, a trickle-charger function guarantees permanent and
optimal recharging of the backup capacitor. Users can match
trickle-charger characteristics to application needs via an internal
programmable resistor. The circuit delivers clock and calendar
information with automatic leap year management. Clock output and
intervals are also programmable to serve as a time reference to the
application. Other features include a programmable alarm function,
2-byte EEPROM and an 8-byte RAM, and a separate 16-bit counter, useable
as a counter or a watchdog function. Additionally, the EM3027 requires
no external components. EM MICROELECTRONIC-US INC., Colorado Springs,
CO. (719) 593-2883.

Learn how to specify bench power supplies
Not all power supplies are created equally! When selecting a general
purpose bench power supply, there are a lot of aspects to consider in
choosing the optimum power supply for a particular application. Plus
there are even more factors to consider to ensure you obtain a clean and
stable DC power output.

Claiming to deliver best-in-class low-light performance for
next-generation camera phones, the OV5630 debuts as the first 5
megapixel CameraChip sensor incorporating the company's proprietary
1.75-micron OmniPixel3-HS architecture. Also launched, the OV5633, a
modified version of the OV5630, targets digital still camera and digital
video hybrid camera markets. The OV5630 and OV5633 both employ
OmniPixel3-HS technology, enabling a low-light sensitivity of 960
mV/(Lux-sec). They offer differing chief ray angles to suit specific
lens requirements and support automatic exposure control, gain control,
white balance, 50/60 Hz luminance detection, and black level
calibration. Both sensors can output data in full 5 megapixel resolution
at 15 fps, and record 720p high definition video at 60 fps or 1080p at
30 fps. In QVGA resolution, they can output data at 120 fps. For
transferring image data, both sensors come with a two-lane MIPI
interface. The OV5630 is available in COB or CSP packaging and the
OV5633 comes in CLCC packaging. Both are sampling with volume production
set for the fourth quarter. OMNIVISION TECHNOLOGIES INC., Sunnyvale, CA.

Suitable for backlighting 5" to 20" LCDs, the CERAMOS reflector LED
provides high brightness and power in a small package measuring 2.3 mm x
3.2 mm x 0.8 mm. Designed for light-guide-based backlighting in high
ambient light conditions, the component fits into light guides as thin
as 2 mm. This feature also makes it viable for edge lighting in LCD TVs
and monitors. The LED employ's patented ThinGaN LED technology that
enables it to operate at 70 lumens per Watt at 80 mA with a lifespan of
50,000 hours. Additionally, its SMD ceramic package handles operating
temperatures up to 150°C and is compatible with standard surface-mount
processes. Other applications include camera flash and strobe lighting,
reading lamps in aircraft, cars, and buses, decorative and entertainment
lighting, and signage or marker lights. For more information, call OSRAM
OPTO SEMICONDUCTORS, San Jose, CA. (888) 446-7726.

Aftermarket Battery Packs - Revelations from Product Tear-Downs
Aftermarket battery packs are available for most portable devices. This
webcast presents the results of several product tear-downs on
aftermarket battery packs, and explains how substandard aftermarket
packs can cut corners on cost, safety mechanisms, and battery
performance. These tear-downs expose electronic & mechanical design
issues, as well as good manufacturing and regulatory violations. Then,
this webcast provides solutions for OEMs to manage and control their
ecosystem of aftermarket battery pack suppliers. This webcast is
applicable to OEMs of consumer and industrial electronic products
susceptible to aftermarket batteries, such as medical, handheld radio,
and data collection devices.

Groomed for rugged industrial installations, the 5.7" LQ057V3DG02
and 8.4" LQ084V3DG01 VGA TFT-LCDs meet the company’s Strong 2 criteria
for industrial display technology, which defines stringent standards for
brightness, contrast, temperature range, shock, and vibration. These
standards include a minimum brightness of 400 nits, standard contrast
ratio of 600:1, operating temperatures ranging from -30ºC to +80ºC,
and certifications for withstanding 60g to 70g of shock and 1.5g to 2g
of vibration. Featuring chip-on-glass technology, the 5.7" LQ057V3DG02
provides a 640 x 480 pixel format and an 18 x LED backlighting system
that provides a brightness of 400 nits. The 8.4" LQ084V3DG01 module
sports a 640 x 480 pixel format and delivers 400 nits of brightness from
a 2 x CCFL backlighting system. Single-piece sample prices for the
LQ057V3DG02 and LQ084V3DG01 are $175 and $300, respectively. SHARP

Version 1.3 of UPC Studio software, a tool for gaining control of
UPC-equipped ac power sources, adds a test manager feature that allows
users to quickly create and run test sequences and plans. Test sequences
consist of one or more output sequences designed to execute a series of
automated tasks that control and monitor the ac power source and other
instruments. Test results are stored in user-defined test reports and
test plans manage complex tasks by allowing the user to link together a
series of test sequences into a single test. The test manager can
automate instrument compliance testing and certification as well as
obtain pre-configured test sequences and test plans. Typical test
sequences include DO-160 and MIL-STD-704 for avionics compliance
testing. Price for the test manager is currently $1,750 with
factory-written test sequences starting at $500. PACIFIC POWER SOURCE
INC., Irvine, CA. (800) 854–2433.
