W typ.
During HALT
122 mW typ.
(3.3 V, 50 MHz)
During execution
238 mW typ.

Note: • The values of power consumption during execution were measured when a test
program that consisted of 55% load instructions, 23% arithmetic operation
instructions, 1% mac instruction, 12% branch instructions and 9% ext
instruction was being continuously executed.
