IDDIO current is dependent on the electrical loading on the I/O pins.
IDDA18 includes current into VDD1A18 and VDD2A18 pins. To realize the IDDA18 currents shown for IDLE, STANDBY, and HALT, clock to the ADC module must be turned off explicitly by writing to the PCLKCR0 register.
IDDA33 includes current into VDDA2 and VDDAIO pins.
The TYP numbers are applicable over room temperature and nominal voltage. MAX numbers are at 125°C, and MAX voltage (VDD = 2.0 V; VDDIO, VDD3VFL, VDDA = 3.6 V).
The following is done in a loop:
  • Data is continuously transmitted out of the SCI-A, SCI-B, SPI-A, McBSP-A, and eCAN-A ports.
  • Multiplication/addition operations are performed.
  • Watchdog is reset.
  • ADC is performing continuous conversion. Data from ADC is transferred to SARAM through the DMA.
  • 32-bit read/write of the XINTF is performed.
  • GPIO19 is toggled.
When the identical code is run off SARAM, IDD would increase as the code operates with zero wait states.
If a quartz crystal or ceramic resonator is used as the clock source, the HALT mode shuts down the internal oscillator.
HALT mode IDD currents will increase with temperature in a nonlinear fashion.
The IDD3VFL current indicated in this table is the flash read-current and does not include additional current for erase/write operations. During flash programming, extra current is drawn from the VDD and VDD3VFL rails, as indicated in Table 5-61. If the user application involves on-board flash programming, this extra current must be taken into account while architecting the power-supply stage.
