Though they only have flash, they don't have the few bytes of EEPROM that the AVRs threw in. -- Rob Gaddi, Highland Technology Email address is currently out of order

Yes, all of them have 128 bit wide flash that allows zero waitstate execution at the maximum CPU clock. -- Failure does not prove something is impossible, failure simply indicates you are not using the right tools... nico(a)nctdevpuntnl (punt=.) --------------------------------------------------------------

Not bad, I ordered a couple books on ARM off Amazon, may get into it finally. From what I see they are same price as AVR mega, low power and much faster. And NXP is very generous with samples. M

If you want something a little smaller the ATtiny48 and ATtiny88 are nice chips. I'm quite a fan of the AVRs personally... Mark.

The books on ARM may be too generic. Most of the things you need to know are in the user manual and the datasheet. NXP's Cortex based LPC1000 series need no assembly at all to get running. Even interrupt routines do not need special care. -- Failure does not prove something is impossible, failure simply indicates you are not using the right tools... nico(a)nctdevpuntnl (punt=.) -------------------------------------------------------------- |
