Nexus 5001 embedded processor debug interface

The Nexus 5001 specification, called the Standard for a Global Embedded Processor
Debug Interface was released by the IEEE in 2003 as IEEE-ISTO 5001.

I added a page to cover the topic on the 6th of January as Nexus 5001 Interface.
I wanted to update the page just now but could not remember the page title. I did a Google search, but nothing showed up, and I paged around with out it finding either.

Looks like I linked to the text off the Design for Test page, which has not yet been spidered by Google yet. I just added another link off the alphabetic listing of buses page, Interface Buses 'N'. The Nexus 5001 standard calls out a connector but I'm not yet sure if it's a 'Cable Bus' or add-on board, 'Mezzanine Bus', guess I need to read the spec. However it definitely is a debug specification that uses the JTAG interface.

I went ahead and added a link to the new page off the Bus Design page, which lists all most all possible interface standards listed on the web site.

Adding this posting will insure that the page covering the Nexus 5001 standard will be spidered now. But it still may be a few days before the topic is indexed on Google or that it shows up on a site search within interfacebus.com. It must be time to generate and up-load a new sitemap to Google, and to update the page to add additional information of the subject.

I did just add yet another new page that provides manufacturing part numbers for Nexus 5001 connectors, Nexus 5001 connector manufacturers. Not really sure how long that page will reside on the web site, part numbers do tend to change. The vendor page has no out-going links, so maybe it's ok to leave it.....

Waveguide Manufacturers

There has been a listing of Waveguide manufacturers posted for a while now. A few days ago I added a page to cover Manufacturers of Waveguide Gaskets. Like many new page additions its small and only contains a few vendors, but over time more manufacturers will be added.

Diode Arrays

Added a few pages to cover Diodes Arrays, off the main Diode Terms page.

One page covers Diode Arrays in a Flat package [Flat Pack Diode Arrays]. While another page covers Diode Arrays in a DIP package [DIP package Diode Arrays].

Both pages provide diode types, schematics and name designations.

How to Derate Diodes at high temperatures

A few of the last posts were related to Transistor Derating Curves. Although that was a new page addition, none of the new pages listed or linked from that page were ever listed here ~ because there were more than a few new pages. Here are a few examples:
2N3762 Transistor Derating Curve.
2N4029 Transistor Derating Curve.
2N6249 Transistor Derating Curve.

Diode Derating Curves have also been added over the last month, with no sub-pages listed here. So here are a few examples of those as well.
1N4954 Zener Diode Derating Curve.
1N5968 Zener Diode Derating Curve.
1N6036 Diode Derating Curve, TVS.

These links are just a sample, the pages have been on the web for a month now and there is no longer a need to re-list them here. However I did want to point out that new pages have been added, but not listed in this blog.

I also started a page on Diode Package Styles, or discrete component packages. The component package styles page is still small with only five sub-pages, but it's a start.

Embedded Board Standards

There are dozens of embedded board standards out there. Many board types are listed on the Industrial Board Formats page, but not every board variation. The page contains links to manufacturers that make a particular style of board.

One of the page links points to all the Mezzanine Card Manufacturers. Which then points to each of the different types of daughter cards. Two new links added include manufacturers that produce an FPGA Mezzanine Card [FMC], and an Express Mezzanine Card [EMC]. A small description of the EMC standard had already been listed as part of the Bus Definitions section, under EMC Mezzanine Bus. Neither of these two bus standards have been released yet, so there are no manufacturers that produce boards.

Another embedded board format that was added is the listing of EPIC Express Board Manufacturers, but because I just now up-loaded the page it's still a copy of the EPIC Board Manufacturers page. Again, the point of the pages is to list companies that produce cards in the listed formats. Only a very small description is provided for each board form factor.
