Operating conditions and power consumption
Operating voltage:
Core (VDD)
2.7 V to 3.6 V
I/O (VDDE)
2.7 V to 5.5 V
Operating clock frequency: Max. 60 MHz (when core voltage = I/O voltage = 3.3 V
±0.3 V)
Operating temperature:
-40 to 85
°C
Power consumption:
During SLEEP
T.B.D
W typ.
During HALT
T.B.D mW typ. (3.3 V, 50 MHz)
During execution
T.B.D mW typ. (3.3 V, 50 MHz)
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.
