32-Bit Microcontroller for New Project
|
| |
I'm about to embark on a new project that will require a 32-bit microcontroller. I've spent the last month evaluating the merits of the various choices architecturely, and have a pretty good idea of what's out there. It's come down to development environments, and I'd like to get some first-hand reports from people on this group.... more »

Does Cypress World Tour Kit docum,entation still exist?
|
| |
Wanted to try some simple stuff with a PSoC and I've got the large kit from the 2006 World tour, the one with four experiment circuits on there. Looking for schematics the closest I found was CY3209 which is very similar but not 100%, and all part designators are numbered differently. Possibly the "old" kit from 2006 was CY3121 but not sure, there is no... more »

SDR SDRAM 16-bit vs 32-bit
|
| |
Given SDR SDRAM with 16-bit width, I have seen both 16-bit and 32-bit (2 x 16-bit) configurations, and am considering which way to go. What are the pros/cons? 1. Cost? 2. Performance? 3. Ease of board layout? [This may have been asked earlier on this forum in some other form ...] Thanks.
