It sure does look like a nice part, and it even comes in PDIP. But how does one buy them? Using http://www.findchips.com (I agree, excellent site) and PartMiner, I can find only one distributer that admits that they exist; Marshall lists a single form of it, the LQFP UPD78F0034GC, at $6.15 each when they have them; however it's out of stock and the quoted lead time is 112 days. The base emulator system (the IE-78K0-NS) is known to Sterling and Future; Future lists it at $4,755, "Call for Stock" -- debug software, adapters, simulators, etc. extra. The assembler, RA78K/0, seems to cost $395, the C compiler $655. It would appear that, should any of these items be available anywhere, a full development system wuold cost as much as $7-10K? Perhaps we could set a new rule: When recommending an alternative part, the recommendation needs to include the cost of the development system and a place one can buy it and the parts. :-) --Bob -- ============================================================ Bob Drzyzgula It's not a problem spam_OUTbobTakeThisOuTdrzyzgula.org until something bad happens ============================================================ http://www.drzyzgula.org/bob/electronics/ ============================================================

Our price was in the $5's (10k/year), and the total dev kit (ICE, *and* IAR compiler) was around $5000. Are you buying from RS or Maplin? ;)) NEC is not in the hobby-ist game, so you won't find onesies and twosies. -- Friendly Regards /"\ \ / Tjaart van der Walt X ASCII RIBBON CAMPAIGN .....tjaartKILLspam@spam@cellpt.co.za / \ AGAINST HTML MAIL |--------------------------------------------------| | GSM Technology for Positioning and Telematics | | Cellpoint Systems SA http://www.cellpt.com | | http://www.wasp.co.za/~tjaart/index.html | | WGS84 -26.0124 +28.1129 Voice +27 (0)11 2545100 | |--------------------------------------------------|

Maybe tubesies? :-) There is a tiny niche between hobby and volume production, where even the cost of a deveopment system is justifiable, but the volumes don't justify, on either side, schmoozing with the local sales force. uChip, Atmel, and many of the 8051 vendors seem to be quite happy making products available to that market. It would be easier if vendors that didn't want that kind of business would be more up front about it: "Our products are only available in carload quantities", or something like that. --Bob -- ============================================================ Bob Drzyzgula It's not a problem bobKILLspamdrzyzgula.org until something bad happens ============================================================ http://www.drzyzgula.org/bob/electronics/ ============================================================
