simultaneously can deliver up to 100W of power from a
single standard USB port, which is 40 times the power
compared to USB 2.0. With up to 100W of available power,
designers can dynamically allocate this power to fast battery
charging and system power.
The UPD1001 is the first of the family and is a highly
flexible and configurable solution that supports the five
USB-IF standard UPD power profiles, plus an additional 25
UPD-compliant profiles for a total of 30 supported by a
single chip. This allows designers to select the optimum
power profiles in order to meet their specific application
Simple configuration is achieved by strapping the two
configuration select pins on the UPD1001. A multitude of
configurations are available to provide utmost flexibility.
Integrated quad-banks of one-time programmable memory
allow for further system customization without the need of
any external memory components.
The UPD100X family serves a wide range of
applications in the consumer (e.g., notebooks, printers and
accessories, docking stations, mobile devices, and battery
chargers), industrial (computers and handheld devices), and
automotive markets (e.g., head units, break-out boxes, and
USB battery chargers), among others.
UPD1001 is supported by Microchip's
UPD1001 Evaluation Kit (US$299.00) and is

VMA Arduino Shields
With Variety of Functions Saelig Company, Inc., has introduced five Arduino shields that can be stacked if
necessary to expand the capabilities of the
ubiquitous Arduino microcontroller platform. Light
control, audio capabilities, motor control, Ethernet
connectivity, and analog and digital I/O are provided
by the VMA Arduino shield range.
Arduino is an open source electronics
prototyping platform based on flexible easy-to-use
hardware and software, and the community of
Arduino enthusiasts is vast. Shields are boards that
can be plugged on top of the 2. 67" x 2.08" Arduino
PCB, extending its capabilities.
The VMA01 RGB shield is a fully stackable
Arduino shield that can control three channels of
lights with full dimming and blending capabilities.
Ideal for lighting projects and DIY stage effects, this
board operates from external 12V or 24V and can
drive up to a 6A load.
The VMA02 audio shield facilitates up to 60 seconds of
voice or other audio signal recording via a built-in
microphone or a line input. Record and playback can be
initiated via an onboard button or via the attached Arduino
controller. The board samples at 8 kHz and can be used for
announcements, warnings, status indicator signals, or
The VMA03 motor and power shield can drive relays,
solenoids, and DC or stepper motors. Two output channels
are provided and the board — which is based on the dual
full-bridge L298P driver — can be powered internally via the
attached Arduino, or by using an external supply. Maximum
output for each channel is 50V/2.5A when using an
The VMA04 Ethernet shield connects an Arduino as a
simple webserver to the Internet in minutes. Operating on
5V supplied from the Arduino board, the VMA04 is based
on a Microchip ENC28J60 IC, and offers data rates up to 10
Mbps. The integrated MAC controller supports Unicast,
Multicast, and Broadcast packets.
The VMA05 I/O shield is a simple way to provide
additional Arduino connections for sensors, controllers, and
