AM4379 RTC mode power consumption

Other Parts Discussed in Thread: AM4379

Hi,

RTC only Mode Current consumption of AM4379 is not mentioned in its datasheet & Power Consumption Summary sheet.

Please tell about the power consumption (current consumption of AM4379 in 1.8V RTC supply rail)

And I am using TPS65218B1 PMIC for powering AM4379 when i am entering RTC only mode. DCDC5, DCDC6 are will be in on condition. Remaining section will be OFF in PMIC. At that time what will be the leakage or shutdown current in all remaining DCDC converters and LDOs?

Thanks,

Ganesh.

Table 5-4 from the AM437X Datasheet Rev. B also gives numbers for VDDS_RTC.

Hi Biser,

Thanks for your immediate reply.

Table 5-4 from the AM437X Datasheet Rev. B is giving the maximum possible current consumption on each rail.

The next link you shared is giving the Suspended(64.58mW) and standby mode(101.7mW) power consumption. Whether any one of this is same as RTC only mode of Processor?

Thanks,
Ganesh.

At the moment this is the only data available. processors.wiki.ti.com/.../AM437x_Power_Consumption_Summary will be updated once new data is available, but I cannot give a time frame for this.
