I could have failed to notice certain significant entries amongst all these guides, but so far what I have found is:
TMS3320C5515 DSP System User's Guide (SPRUFX5)
p 33 - 1.5 Power Management ... There are two components to power consumption: active power and leakage power.
p 34 - 1.5.3 Clock Management... The device supports clock gating features that allows software to disable clocks to entire clock domains or modules within a domain in order to reduce the domain's active power consumption to very-near zero (a very small amount of logic will still see a clock).
p 38 - 1.5.3.2 Peripheral Domain Clock Gating The peripheral clock gating allows software to disable clocks to the DSP peripherals, in order to reduce the peripheral's active power consumption to zero. ... Some peripherals provide additional power saving features by clock gating components within its peripheral boundary. See the peripheral-specific user's guide for more details on these additional power saving features.
p 21 - 1.3 Device Clocking ... RTC core (CVDDRTC) must be powered all the time
p 45 - 1.5.3.5 RTC Domain Clock Gating ... Note that the RTC oscillator, and by extension the RTC domain, can be permanently disabled by not connecting a crystal and tying off the RTC oscillator pins. However, in this configuration, the RTC must still be powered ...
p 48 - 1.5.4.3 Internal Memory Low Power Modes
To save power, software can place on-chip memory (DARAM or SARAM) in one of two power modes: memory retention mode and active mode.
TMS320C5515 Data Sheet (SPRS645B)
p 67 - ICDD:
Core (CVDD) supply current ...
Analog PLL (V VDDA_PLL) supply current ...
SAR Analog (VDDA_ANA) supply current ...
I have found no power or current consumption specifications in:
TMS320C5515/14/05/04 DSP Real-Time Clock (RTC) User's Guide (SPRUFX2)
TMS320C5515/14/05/04 DSP External Memory Interface (EMIF) User's Guide (SPRUGU6)
TMS320C5515/14/05/04/VC05/VC04 DSP Universal Asynchronous Receiver/Transmitter (UART) User's Guide (SPRUFO5)
TMS320C5515/14/05/04 DSP Inter-IC Sound (I2S) Bus User's Guide (SPRUFX4)
TMS320C5515/14/05/04/VC05/VC04 DSP Inter-Integrated Circuit (I2C) Peripheral User's Guide (SPRUFO1A)
TMS320C5515/14/05/04 DSP Direct Memory Access (DMA) Controller User's Guide (SPRUFT2)
So, have I failed to look in the right place, or are the following not specified?:
1. Where are clock domain active supply currents specified and at what clock / data rates?
2. Where are peripheral active supply currents specified and at what clock / data rates and under what configurations?
3. Where is RTC supply current specified?
4. Where is DSP leakage current specified?
5. Where are internal memory active supply currents specified for each mode?
