6.7 Power Consumption Summary

Table 6-3 and Table 6-4 summarize the power consumption at the power terminals.

Table 6-3 Maximum Current Ratings at Power Terminals
PARAMETER(1)SUPPLY NAMEDESCRIPTIONMINTYPMAX(1)UNIT
Current consumptionVDD, VDD_SRAM, VNWATotal current drawn by all nodes driven by 1.2V rail2000mA

(1) The specified current values are at Max supply voltage level (Recommended operating conditions).
(2) The exact value will depend on the system use case and design.
Table 6-4 Average Power Consumption at Power Terminals
PARAMETER CONDITION(2) DESCRIPTION MIN TYP(1) MAX UNIT
Average power consumption in single chip mode. 3TX, 4RX 25% duty cycle Use Case:

76-77GHz chirps (for 50% duty cycle) and 80-81GHz chirps (for 25% duty cycle);

Regular mode, 37.5Msps sampling rate, 25.6 ms frame periodicity, 256 chirps/frame, 2-µs idle time, 50-µs ramp end time, 7us ADC start time and excess ramp time
Activity of cores :
  • 70% MSS R5F
  • 70% C66x DSP and HWA
  • 50% Arm M4F

All the above cores under-clocked/clock-gated during idle times);

Ethernet is enabled for data transfer		 1.37 W
50% duty cycle 1.98
4TX, 4RX 25% duty cycle 1.44
50% duty cycle 2.11
(1) The Power consumption numbers are for a typical usecase i.e. for a Nominal device at 25C ambient temperature and nominal voltage conditions.
(2) Frame duty cycle represents the ratio of Frame Active and Total Framing time (including Interchirp and Interframe time).
