5.3 Electrical Characteristics
5.3.1 Power Consumption
NOTE
Power consumption on this device depends on several operating parameters such as operating
voltage, operating frequency, and temperature. Power consumption also varies by end applications
that determine the overall processor, CPU, and peripheral activity. For more specific power
consumption details, see Estimating Power Consumption on the TMS320C5517 Digital Signal
Processor [literature number SPRABV3]. This document includes a spreadsheet for estimating
power based on parameters that closely resemble the end application to generate a realistic
estimate of power consumption on this device based on use-case and operating conditions.

(1) For test conditions shown as MIN, MAX, or TYP, use the appropriate value specified in the recommended operating conditions table.
(2) The USB I/Os adhere to the Universal Bus Specification Revision 2.0 (USB2.0 spec).
(3) V_DD is the voltage to which the I2C bus pullup resistors are connected.
(4) Applies to all input pins except WAKEUP, I2C pins, GPAIN[3:0], RTC_XI, and USB_MXI.
(5) I_SD is the amount of current the LDO is ensured to deliver before shutting down to protect itself.
(6) I_I applies to input-only pins and bidirectional pins. For input-only pins, I_I indicates the input leakage current. For bidirectional pins, I_I
indicates the input leakage current and off-state (Hi-Z) output leakage current.
(7) When CV_DD power is "ON", the pin bus-holders are disabled. For more detailed information, see Section 5.7.2.3, Digital I/O Behavior
When Core Power (CV_DD) is Down.
(8) Applies only to pins with an internal pullup (IPU) or pulldown (IPD) resistor.
