I have checked out the "Cool Runner" family on the Xilinx Web site and they look ideal, especially with the free Web-based design tools (anyone tried these?). Oddly, my Farnell catalogue shows these as "available until stocks exhausted", although I don't see any sign elsewhere of them becoming obsolete - maybe Farnell have lost their franchise for these. Alternatively, if the logic minimises nicely, then I may try one of the PAL or PEEL parts instead as I have used these before (albeit back in the days when they were definite "Hot Runners"!). I do intend to run off a 3V supply for optimal battery life, except for one specialised part for which there is no 3V equivalent and which will therefore require its own separate regulator or DC-DC converter. But life's like that, isn't it? :-) Thanks once again. - -- Ian Chapman Chapmip Technology, UK -----BEGIN PGP SIGNATURE----- Version: PGPsdk version 1.7.1 iQA/AwUBO/atL2DomaPdnknQEQIeZgCgywEPmiFajzauu86L3fzEMjXKUcMAoKHq TQbYtCE/d8Nrhx3tRuUSssMz =7lhJ -----END PGP SIGNATURE----- -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
