I want to order a xilinx xc9536 cpld. In one catalog I found the following 9536 XLX 44 PLCC In-system Programmable FLASH CPLD, 15ns, 100MHz XC9536-15PC44C. 384-8980 9536 XLX 44 PLCC In-system Programmable FLASH CPLD, 10ns, 100MHz, 3.3V (IND TEMP) XC9536XL-10PC44C 384-9016 What are the 15ns and 10ns respectively refer to ?
cpld version?

Good question. It's the pin-to-pin logic delay of the device. XC95xx come in several sizes (macrocells) each size is tested and given a speed rating, -10, -7, -15 etc. This figure is the tpd in nanoseconds: you can expect to pay more for the faster devices, but with the benefit that you can run them at a higher frequency. The way to distinguish them is in the part number XC95288-10HQ208C ^^^^^^^^ = 288 macrocell xc9500 ^^^ = 10ns tpd ^^^^^^^= 208 PQ package with heat sink ^ = commercial temperature grade One vital thing to note is that this is NOT the same as FPGA markings, FPGA have a speed grade, which does not directly correspond to any tpd, and higher numbers are FASTER, the opposite of CPLD markings (from my experience) Just my 2p Ben The silicon is qualified in terms of gate delay, "Uwe Bonnes" <bon@hertz.ikp.physik.tu-darmstadt.de> wrote in message news:epqdaj$ngp$1@lnx107.hrz.tu-darmstadt.de...> carshie wrote: >> I want to order a xilinx xc9536 cpld.

> Did you take a look at the datasheets?Having looked in the datasheet (belatently) there is another question, in the top of the datasheet the pin to pin delay is quoted as 5ns, then down below we see also 6ns 7ns 10ns 15ns. So do they mean to say that 5ns is the fastest one, but slower one are also available? Another question, I have here a xc9536 which has the following marking xc9536 tm pc44amm0521 f3002413a 7c What speed would it be? I can't find the ordering number on the part, or should have I made a note of it when I bought it (so how would I to know if my supplier did not send me a different spec?)> > -- > Uwe Bonnes bon@elektron.ikp.physik.tu-darmstadt.de > > Institut fuer Kernphysik Schlossgartenstrasse 9 64289 Darmstadt > --------- Tel. 06151 162516 -------- Fax. 06151 164321 ----------

The final 7c stands for "speed-grade 7, commercial temperature grade, 0 to 70 degrees centigrade) Peter Alfke On Jan 31, 8:50 am, <carshie> wrote:> > Did you take a look at the datasheets? > > Having looked in the datasheet (belatently) there is another question, > in the top of the datasheet the pin to pin delay is quoted as 5ns, then > down below we see also 6ns 7ns 10ns 15ns.

Did you actually look at Solution2? You may not be using Virtex-4 but the rest of the lines appear verbatim correct to your description. <carshie> wrote in message news:45c0dca6_2@mk-nntp-2.news.uk.tiscali.com...>> See Answer Record 1067.

Changing the "10C" to "7C" in the illustration to match your part would make the following text applicable: Line 4 Device speed grade (7) and temperature range (C). If a grade is not marked on the package, the product is considered commercial grade. In addition to the mark shown above, Line 4 can contain a few other variations as described below: 7C xxxx The "xxxx" indicates the SCD for the device. An SCD is a special ordering code that is not always marked in the device top mark. 7CES The "ES" indicates an Engineering Sample (as opposed to a production device). 7CESn The "n" is a numeral (1, 2, 3, etc.) The "ES" indicates an Engineering Sample, the "n" indicates an ES revision code. For example, ES1, ES2, ES3, etc. Please see Errata for appropriate information. To obtain Errata, you must register for MySupport, see (Xilinx Answer 21491). 7CESnL or 7CESnR This part marking is used only for Virtex-4 FX engineering sample devices. The "L" indicates that only left (column 0) MGTs are available and the "R" indicates that only the right (column 1) MGTs are available when looking at the device from the "bottom-up."
