This is generally true about most ARM7's, but the lpc2103 is a special
device. It has special circuitry to power down portions of the chip
that aren't being used, and it's sleep performance is also better.

The spec sheet was just updated recently with some current info.

Active mode (no peripherals in use), 1.8 volts
10 Mhz  = 7 ma typ
70 Mhz = 41 ma

Sleep mode = 7 ua (micro-amps)

This is incredibly good for an Arm! The new lpc2888 is also supposed
to be designed with low power consumption in mind.

If you need less current than this, you can use an MSP430, but it's
going to be slower.
