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 bob@drzyzgula.org until something bad happens ============================================================ http://www.drzyzgula.org/bob/electronics/ ============================================================
