UPAMD/P1823 Status Report to the Microprocessor Standards
Committee 11 October 2010 UPAMD currently has 129 participants on the UPAMD Reflector.
Of these there are 20 to 25 active in the work on the standard. The working group has adopted a set of overall goals, on 3
August 2010, for the standard. These are: 1.
Life expectancy of 10 years for Standard 2.
Same connector for All device and adapter connections, if detachable cable. 3.
Power range >10W – 130W delivered power to device and is brand, model,
and year agnostic. 4.
First adapter must work with last device and last adapter with first device.
Standards Compatibility 5.
Adapter<->Mobile Device communications required for higher power safety
<0.7W Non-Sparking. 6.
Standard designed to support Certification testing of adapter, device and cable
7.
Continuous communications growth to support growth of UPAMD capability. 8.
Basic power delivery mechanism to support non-battery and battery powered
devices 9.
Device may be capable of being a source as well as a sink of power. 10.
Make independent of rapidly changing technology 11.
Consider future mobile device design options; Smaller profiles, shapes, and
mounting positions 12.
Connector must not mate with any current designs – no confusion, 13.
Apply KISS principle – Keep It
Simple Stupid within the other goals. Three subcommittees have been formed to address the three
major areas for decisions and specifications: Power
Subcommittee – Chaired by Paul Panepinto – to define the safe
starting voltage and working voltage(s). Communication
Subcommittee – Chaired by Edgar Brown – to define the communication
protocol and techniques. Connector
Subcommittee – Chaired by Mark Anderson – to define the common
connector. The main website is http://grouper.ieee.org/groups/msc/upamd
Subcommittees have working directories off the main site. To
join the reflector, send plain text email, no signatures etc, to
listserv.ieee.org with a simple “subscribe upamd <your-first-name
your-last-name>”. Meeting of the main group is every two weeks, alternating
between Asian friendly and Europe friendly time slots. The next meeting is on
Tuesday 12 October. See http://grouper.ieee.org/groups/msc/upamd/meetings/Agendas/UPAMD_PrelimAgenda_12October2010.pdf
for details. Current goals is to be ready for Sponsor Ballot in Q1
2011. Please note that I am always optimistic. Respectfully; Bob Davis Chair UPAMD/P1823 bobd@xxxxxxxx 408.353.4990 desk 408.857.1273 cell bob.davis.scsi.com Skype |
