  IIRC Atmel's AT91M40800, AT91RM3400 and AT91RM9200 can operate between 
1.65 and 3.6V. Also, the new Atmel SAM7 microcontroller have IOs that 
operate down to 1.65V. (SAM7 chips also feature an on-chip 100mA 1.8V 
regulator for 3.3V-input systems, however you still need at least 3V for 
the Flash supply and the ADC).

  I don't know if there are other easily available ARM7TDMI micros that can 
fully operate at 1.8V...

  What are you trying to achieve?

  Regards.
