Umm... 
- LPC3180 loads nand flash to internal SRAM
- May be they will load from USB/SPI,I2C in future. 16KBROM inside.

Have not seen a chip that boot from SD.  but the AT91sam9261 does
boot from serial eeprom and run on 160KB internal SRAM.  Here's a
copy of what the datasheet says:

<<< Bootloader supporting a wide range of non-volatile memories
Downloads and runs an application from external storage medias into
internal SRAM:
- SPI DataFlash connected on NPCS0
- Two-wire EEPROM
- 8-bit parallel memories on NCS0 >>>

There is development kit from atmel but do not know if chip is
available. Old data sheet in QFP208 but chip now ended up as BGA317.

The LPC3180 spec is weird...Hee... I think may be marketing guys
forgot to look at what the other competitors' (Intel, Samsung,
Cirrus Logic, Atmel) chips features before coming out one.. :)
Sorry... ARM9 is some "rotten" market.
I'm curious and can someone tell me what type of market this LPC3180
is targeting at?? (What??  No LCD, No ethernet?? no...)

Anyway, most of my application requires flash memory read 
protection, and so I will be sticking to LPC21xx.

Regards
