We have added a parametric search capability for the Device Database. Parametric searches help you locate a chip (or chips) with a particular set of features or requirements (like A/D, D/A, I/O, RAM, ROM, and so on). Take a look and let us know what you think. http://www.keil.com/dd/parm_search.asp Jon P.S. Since we now support around 550 devices, the search should return a wide variety of devices.
With its on-chip programmable logic, the Triscend E5 should match just about any and all of the peripheral queries - but it doesn't seem to.
the Triscend E5 should match just about any and all of the peripheral queries Since this device is a SoC, I think you are right. So, what values should be listed in the table for the NUMBER of serial ports and A/D converters and bits of resolution? Maybe I need to add a notes section for some of the more flexible devices. Jon
Another check box for programmable logic should do the job.
"Another check box for programmable logic should do the job." that sounds like a good idea. Possibly with some indication of the size/complexity - but that's notoriously difficult to compare between vendors! :-(
I've thought about this and I think that SoC devices must have the programmable logic status as well as the approximate number of available ASIC gates. But, that leads back to the original problem of how many UARTs, A/Ds, D/As, and so on should be listed. Maybe the maximum reasonable number allowed? Jon
"back to the original problem of how many UARTs, A/Ds, D/As, and so on should be listed." Yes, that is indeed a problem! The E520 has 2048 CSL "Cells", and a full UART can be imlpemented in anything from 152 to 360 Cells (depending on whether you also want FIFOs, modem-control, etc, etc) So that's a max limit of 5-13 full UARTs - but then you wouldn't be able to add any other "soft" peripherals! And programmable logic means you can do things like only have "half" a UART if you only need to receive or transmit, but not both...
