New Family of USB Power Delivery Controllers from Microchip

June 19, 2014

PR_UPD1001-7x5Finally Microchip announces the first device of a new family of USB Power Delivery Controllers, the UPD1001.

The new device is a highly flexible and configurable solution that supports the 5 USB-IF standard UPD power profiles plus an additional 25 UPD-compliant profiles for a total of 30 profiles supported by a single chip. This will allow designers to select the optimum power profiles in order to meet their specific application requirements.


  • Support 5 defined USBPD power profiles + 25 additional user’s defined profiles
  • Fully integrated. Microprocessor and USBPD controller
  • Offering integrated ADC for Voltage/current  monitoring
  • Coming with a ready-to-use UPD1001 Evaluation Kit (part # EVB-UPD100).  It integrates everything you need for a USB Power Delivery provider.
  • Delivered in Consumer (0°C to +70°C),  Industrial (-40°C to +85°C) and Automotive  (-40°C to +105°C) grade



  • Only provider, meaning not supporting  swap features. Looking at the published UPD100x family roadmap, we should wait for the UPD1002 to have the role swap available.
  • Compliant with USBPD v1.2. We are currently at v1.3
  • Not clear the level of flexibility and programmability



USB Power Delivery: looking for a tester?

March 6, 2014

I attended the USB Power Delivery Interoperability event in Portland on middle of Jan. The opportunity was to test the CT20600 USB-PD complete solution from Canova Tech.

During the test sessions, I had the opportunity to touch the new USB test solution from Ellisys, a worldwide leader in protocol test and analysis solutions. The USB Explorer 350, just announced in the company news,  is intended for technology developers working on products employing features specified in the recently released USB Power Delivery specification.

Ellisys EX350

Waiting for the USB Power Delivery compliance procedures delivery from, the USB Explorer 350 could be a valid and powerful instrumentation helping developers to characterize protocol compliance of silicon, software, and systems and to verify corner case communications. The device can be configured to play as a protocol analyze by sniffing the communication between two USB-PD devices or as emulator (producer or consumer).


It comes with a powerful software GUI that enable a complete monitor, analysis and control of the communication protocol. For a detailed description and list of features, please check product page.

A USB-PD Analyzer and Emulator is a great tool for developers and designer to test their products and to be ready for final product qualification and compliance tests. The Ellisys  USB Explorer 350 is the first solution in the market, most probably not the only one in the short term. I’ll check the web for other solutions and/or similar products.


Is the USB Power Delivery a Game Changer?

October 28, 2013

The first USB PD devices will come to market in 2014, with a “big roll-out” in 2015, says Brad Saunders of Intel. Gregory Reed, of the Swanson School of Engineering at the University of Pittsburgh, calls the new USB standard a “game-changer”.

This is an extract of an interesting article from The Economist related to the USB Power Delivery: The humble USB cable is part of an electrical revolution. It will make power supplies greener and cheaper.

Anyone interested on USB-PD and in general on new technology should read.


USB Recharge port on HP Chromebook 11: One port to rule them all

October 14, 2013

A newborn  just enter entered in the always growing family of Chromebook devices: the HP Chromebook 11.


What captured my attention is the unusual charge solution: not anymore hp-chromebook-11-micro-usba dedicated jack to connect an external charger, but a microUSB, as described by JR Raphael in his review. Like our portable devices, smartphones or tabled. This is a great news in my perspective, at least for two reasons.


It is the first step to standardize the recharger mechanism: no more custom and proprietary jacks and charger, but an universal main adapter with USB connection compatible with all our device, hopefully with more then one USB port to recharge many device at a time. One Ring to rule them all. This will impact the final price of the device, too.

Power Flexibility

A single connector will simplify our life. But soon users will ask to have more flexibility. To recharge batteries in a faster mode delivering more power and to use this port to recharge portable device as well, or to supply external peripherals. In one word, USB Power Delivery technology. Able to deliver up to 100w over USB cable.


This device is the first step in the direction of simplifying our life among different and proprietary chargers, jacks and connectors. I hope to see more device implementing this bold solution with a step forward toward USB power delivery and more peripherals and devices taking advantage from this technology.


The Most Promising Technologies for Super Fast Charging

September 27, 2013

The dream of any user of mobile devices is to have its batteries always charged. The second is to have the possibility to charge the batteries as fast as possible, while preserving battery life.


While the identification and introduction of new battery technologies is a complex innovation process with a long time to market, a big effort is spent to define and impose new ways to deliver more power in charging mode, making the life of the user more and more easier.

This approach involves the definition and adoption of new standards based on common and shared specifications and it involves the creation of a new ecosystem of connectors, cables, chargers, adapters and semiconductor solutions. The time to market in this case is much faster and new solutions are popping-up in the last year.

The most promising alternatives are:

  • Wireless Charging
  • USB Power Delivery
  • Qualcomm Quick Charge

USB Power Delivery Showcase from INTEL

July 11, 2013

At the Technology Showcase at IDF Beijing, INTEL demonstrated a typical application of the USB Power Delivery feature: a portable PC delivering through a USB2.0 connection video streaming at 480Mbit/s (not really a big deal) and at the same time the power to supply a LCD monitor.

Developing a USB Power Delivery device? Let’s talk about solutions!

July 1, 2013

Are you thinking to develop or evaluate an USB-PD device? If yes, I’m sure the first problem you are facing is the unavailability of USB-PD semiconductor solutions to build your concept board and of USB-PD enabled products to be used as peer for your system (at least at this date). This is for sure a major issue to assess the system requirements and to evaluate the performances. The possibility to have a USB-PD evaluation board permits the engineering team to start playing with this new protocol, to build the system and to start the implementation and debug of the high level functionalities.

Up to date two solutions are available in the market: one coming from Obsidian Technology and one from Canova Tech.

Everything I know about Obsidian can be found in the website. They came as first in the market with an USB-PD solution and they are offering an USB-PD development board  (OTS9102) based on a proprietary IC (OTI9121) implementing the physical layer (PHY).


More I can say about Canova Tech (sorry, it’s the company I’m working for!). It’s currently developing an USB-PD PHY block, the CT20600.

The CT20600 is a USB-PD compliant PHY IP implementing all the features described in the current USB-PD specifications. The block can be integrated in a more complex power management unit (see previous post) or in standalone device for cost sensitive applications. The CT20600 can be ported to most of the analog CMOS processes available in the market.

CT20600 DVLP Board 1V1

A development board has been developed in order to assess the architecture and to implement the digital blocks of the PHY and the upper layers, like the protocol layer. Waiting for the incoming silicon samples, at the moment the board v1.1 implements the analog parts of the USB-PD PHY using discrete components and the digital blocks in a FPGA.

A detailed description of this board will follow soon.

Any comment and feedback is welcome.
Stay tuned.
