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

For this device, these currents were measured with average activity (50% high/50% low power) at 25°C case temperature and 100-MHz EMIF. This model represents a device performing high-DSP-activity operations 50% of the time, and the remainder performing low-DSP-activity operations. The high/low-DSP-activity models are defined as follows:

High-DSP-Activity Model:

CPU: 8 instructions/cycle with 2 LDDW instructions [L1 Data Memory: 128 bits/cycle via LDDW instructions;

L1 Program Memory: 256 bits/cycle; L2/EMIF EDMA: 50% writes, 50% reads to/from SDRAM (50% bit-switching)] McBSP: 2 channels at E1 rate

Timers: 2 timers at maximum rate

Low-DSP-Activity Model:

CPU: 2 instructions/cycle with 1 LDH instruction [L1 Data Memory: 16 bits/cycle; L1 Program Memory: 256 bits per 4 cycles; L2/EMIF EDMA: None]

McBSP: 2 channels at E1 rate

Timers: 2 timers at maximum rate

The actual current draw is highly application-dependent. For more details on core and I/O activity, refer to the TMS320C6711D/12D/13B Power Consumption Summary application report (literature number SPRA889A).
