What would be the typical current or power savings for a TMS320F28074 to be in IDLE mode instead of active? Assume operation at 120 MHz. In idle mode, the peripherals of interest would be the ADC and DMA and PWM. PWM will be used to turn on LEDs in a round robin fashion for 400 µs pulses. ADC values will need to be taken and stored to RAM using the DMA. Is the CLA of the TMS320F28075 considered a peripheral or a CPU that will be gated or powered down?
The datasheet doesn't include a whole lot of detail about low power consumption or active mode consumption for the C2000. I understand the MSP430 is designed specifically for low power operation, but the peripherals of the C2000 are more appealing.
