My manager can't locate P87C51RB-4N on Digikey (and a few other sites which I can't remember). He mentioned that Arrow is a four week lead time. I wouldn't mind using the P89xxx as alternative. There is nothing magic about Philips. Other manufacturers would be OK. The key is I need the EROM. Thanks, Doug
Doug; Suggest that you contact your local Philips Rep. For you, I beleive that is 972-705-2485. All MCU are streching out and the 40Pin parts are just not too popular but the Reps might have a sample or two until you can get your's ordered. Also, there are a number of Semiconductor brokers that have access to older or less used parts. They normally have parts the Distributors don't stock but they also have high prices. Good luck.
