Input capacitance

Output capacitance

(1)

For test conditions shown as MIN, MAX, or NOM, use the appropriate value specified in the recommended operating conditions table.

(2)

II applies to input-only pins and bi-directional pins. For input-only pins, II indicates the input leakage current. For bi-directional pins, II

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)

IOZ 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. 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).
