(1) For test conditions shown as MIN, MAX, or TYP, use the appropriate value specified in the recommended operating conditions table.
(2) LVCMOS pins are all I/O pins powered by DVDD, DVDD_GPMC, DVDD_GPMCB, DVDD_SD, DVDD_C supplies except for I2C[0] and
I2C[1] pins.
(3) 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.
(4) Applies only to pins with an internal pullup (IPU) or pulldown (IPD) resistor.
(5) I_OZ applies to output-only pins, indicating off-state (Hi-Z) output leakage current.
(6) 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 TMS320DM814x/AM387x Power Estimation Spreadsheet
Application Report (Literature Number: SPRABO3). To determine the worst-case power consumption values, use the
TMS320DM814x/AM387x Power Estimation Spreadsheet Application Report.
