(1) The I
DD numbers in this table are valid for the TMS320C28345 and TMS320C28343 devices only. For the TMS320C28341 device, subtract the I
DD current numbers for those peripherals that do not exist on this device (see
Table 5-3) from the I
DD current numbers shown in this table.
(2) IDDIO current is dependent on the electrical loading on the I/O pins.
(3) 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.
- Floating-point multiplication and addition are performed.
- 32-bit read/write of the XINTF is performed.
- DMA channels 1 and 2 transfer data from SARAM to SARAM.
- GPIO19 is toggled.
(4) If a quartz crystal or ceramic resonator is used as the clock source, the HALT mode shuts down the internal oscillator.
NOTE
The IDD numbers in Table 5-2 are valid for the TMS320C28345 and TMS320C28343 devices only. For the TMS320C28341 device, subtract the IDD current numbers for those peripherals that do not exist on this device (see Table 5-3) from the IDD current numbers shown in Table 5-2.
