@electrnx_lyf: Why do product developers choose this over the microcntollers which come with the actual application circuits or the close to real hardware the companies generally like to produce. Do the Lattice really have some proven example products where there will be benefit by using these IC's.

Microcontrollers are very versatile -- and it's great being able to modify your programs -- but these types of processors (MPUs, CPUs, DSPs) are really not very efficient power-wise because of the way they handle instructions one at a time -- by comparison, in th ecase of an FPGa you can b edoing lots of things simultaneously at a much lower clock speed (hence lower power).

The iCE40 devuces ahave been engineered for ultra-low-power (thsi is the old Silicon Blue technology) -- the Lattice having proven example products .. .I think they are selling more than a million of these devices a week (maybe a day -- I'll check with them) -- so I guess they do LOL

I just bounced over to the synflo site -- the C~ looks very interesting -- woudl you be interested in writing a short column on this for me to post on EE Times? Email me directly at max.maxfield@ubm.com to discuss.

Now if only you could program these brand new FPGAs as simply as you write code for MCUs, without the need to write Verilog or VHDL and other similar low-level cryptic languages/frameworks, then most developers (including software developers) could actually use them, rather than just hardware designers.

Wait but you can! With a modern programming language with a C-like syntax that is tailored for hardware design. It's probably the best choice for developers looking to replace their MCU by a FPGA. And it's free and open-source! Check it out on synflow.com and let us know what you think on our forum.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
