A Deeper Dive into Efinix with VP of Marketing Mark Oliver

The FPGA community is tiny. You can count the number of FPGA vendors on one hand, if you neglect to count the three or four vendors in China who are dedicated to their domestic market. Anyone familiar with the FPGA market can likely name AMD (the FPGA company formerly known as Xilinx), Altera (the FPGA company formerly known as Intel PSG, which itself was previously known as … Read More → "A Deeper Dive into Efinix with VP of Marketing Mark Oliver"

Want to know the future of new memories (MRAM, FRAM, PCM)? Tom Coughlin and Jim Handy make predictions

I’ve been following alternative and persistent memory technologies for 40 years. Back in the 1980s, all we had for semiconductor memory was SRAM, DRAM, EPROM, and {non-Flash) EEPROM. During the late 1980s, when I first transitioned from working as an engineer to an editor for an electronics publication, I wrote about nascent, low-capacity, persistent memories offered by two companies located in Colorado Springs: ferroelectric memory (FRAM) made … Read More → "Want to know the future of new memories (MRAM, FRAM, PCM)?

It all depends -- which lumps? On the outside of what? LOL
Posted on Mar 14 at 7:55am by Max Maxfield
Nope -- all the capacitors are underneath the card -- I'm informed that the big brown boxes represent DC-DC converters and the small brown boxes represent inductors -- or maybe it's the other way round -- see this complementary/related column I wrote a month ago -- they also talk ...

Or did you mean the lumps on the outside???
Posted on Mar 14 at 4:51am by DaveN
Max! Capacitors everywhere (brown), not inductors, right? Hope you are well, See ya, Dave

We used to use 2000A at 5V to power an entire mainframe back in the day (if that day was in 1980), and we thought we were cool (and hot at the same time).

People casually throw around words like "awesome" - but this truly is. That is a LOT of Watts per square inch - let's face it - that's a lot of Watts for anyone's tea-party! Ouch, triple ouch. (And I mean that most sincerely!) Thanks Max - that really is eye-watering ...
