Hi folks!

I've just been eying the new LPC1830 part. I find it attractive especially because of its Hi-Speed ability.

I've been running through documents and was unable to locate any application information regarding the hi-speed USB interface. Usually it was included in the devices datasheet, a schematic or something similar. Has anyone managed to engineer a working hi-speed bus yet? I cannot find any information whether the hi-speed termination resistors are on-chip, or if the PHY requires pull-downs in host mode, etc... I did look at Keil's MCB1800 schematics and they are void of anything. Can someone confirm that?

Regarding the chip revision. I saw the errata for the '-'-part and I almost got stunned. Alot of things went "wrong" in that revision. Is it still in circulation and was it delivered to distributors? I wouldn't want to land on one after manufacture to have non-working interfaces on the board. Especially cumbersome is the SPIFI errata for flashless parts, which seem to be the only ones available at the moment. BTW, did anyone come across any approximate or semi-approximate dates for parts with internal flash?

I also wonder how SPIFI fares against internal flash. There are no solid numbers, just some 90ns NOR flash comparisons with raw throughput, but the internal flash does usually have the flash accelerator backing it up, while SPIFI mentions no such thing.

Well, lots of unanswered questions wandering around in my head... :)

Thank you for taking the time.

Regards,
Matt
