(...) Yes, I suspect the same. The ROM mask *is* the custom part of the chip that LEGO can easily define without big expenditures. I noticed that the atmel chip also has a boot ROM that is separate from the flash. If they use that chip we might (...) (20 years ago, 15-Jan-06, to lugnet.robotics)

Hello Trevyn, (...) That's the Hitachi H-8 Microcontroller. It is merely silk-screened with the Lego logo, they had nothing at all to do with it's development. (20 years ago, 15-Jan-06, to lugnet.robotics)

Hi Chris, (...) I'd guess at the AT91SAM7S256, the ST type has a lot of stuff that isn't needed (CAN, smartcard interface, HDLC interface) and 16K extra flash which aren't mentioned in the LEGO press release. See (URL) and (URL) Also take a look at (...) (20 years ago, 15-Jan-06, to lugnet.robotics)
