Could someone familiar with both LPC21xx and STR91x help giving 
some quick comparison of the 2-chips??

- Raw CPU performance:   1.5-2x ??
- IC Package, I/O:  I saw 48 I/Os on LQFP80 (which is not very 
  much bigger than LQFP64)
- On chips peripherals: uart, i2c, spi, timer, can, usb, adc/dac,
  dma, ethernet...
- Supplies:  LPC2148 has internal 1.8V LDO
- Power consumption: how low power? meeting usb bus-powered
  requirements?
- Development Tools Supporting: JTAG downloading? Can't be
  as "engineer friendly" as LPC2148, right?
- Compilers Supporting: Any GCC or commercial ARM7/9 compilers,
  right?
- Pricing, price trend:  STR91x is "Stacked die"
- Memory Code Read Protection:  Is it more reliable on STR91x??

Sorry to start such a thread on this LPC21xx group... 
and This is comparing apple/arm7 to orange/arm9..    :)
