Idle refers to ADSP-2181 state of operation during execution of IDLE instruction. Deasserted pins are driven to either V
DD
or GND.
10
I
measurement taken with all instructions executing from internal memory. 50% of the instructions are multifunction (types 1, 4, 5, 12, 13, 14), 30% are type 2
and type 6, and 20% are idle instructions.
11
V
= 0 V and 3 V. For typical figures for supply currents, refer to Power Dissipation section.
12
Applies to T QFP and PQFP package types.
13
Output pin capacitance is the capacitive load for any three-stated output pin.
