(1) For test conditions shown as MIN, MAX, or NOM, use the appropriate value specified in the recommended operating conditions table.
(2) I_I applies to input-only pins and bi-directional pins. For input-only pins, I_I indicates the input leakage current. For bi-directional pins, I_I
indicates the input leakage current and off-state (Hi-Z) output leakage current.
(3) Applies only to pins with an internal pullup (IPU) or pulldown (IPD) resistor.
(4) I_OZ applies to output-only pins, indicating off-state (Hi-Z) output leakage current.
(5) Measured under the following conditions: 60% DSP CPU utilization doing typical activity (peripheral configurations, other housekeeping
activities); DDR2 Memory Controller at 50% utilization (135 MHz), 50% writes, 32 bits, 50% bit switching; 2 MHz McBSP0 at 100%
utilization and 50% switching; Timer0 at 100% utilization. At room temperature (25 C) for typical process ZWT devices. The actual
current draw varies across manufacturing processes and is highly application-dependent. DM643x DMP devices are offered in two basic
options: lower-power option and high-performance option. Low-power devices offer lower power consumption across temperature and
voltage when compared with high-performance devices. However, high-performance devices offer higher operating speeds. For more
details on core and I/O activity, as well as information relevant to board power supply design, see the TMS320DM643x Power
Consumption Summary Application Report (literature number SPRAAO6).
