6. Extended Sleep mode consumption

Now, you have the ability to use your customized scatter file to squeeze RAM memory size. For Sleep mode configurations and power measurement you can refer to this Tutorial. This tutorial gives you details on the firmware, hardware, software/tools environment used to measure the current consumption of different power modes mainly for extended sleep mode.

The DA14585 Datasheet and DA14586 Datasheet show current consumption values in the section DC Characteristics for 32 KB RAM retained (48 KB RAM retained are not given in the datasheet)

for 25degC and with optimized LDO settings here are typical Buck application values for extended sleep current consumption:

Table 1 DC Characteristics

Retained RAM size	Values
32kB (Block 4 Retained)		1.8uA
64kB (Block 1 and 4 Retained)		2.9uA
96kB (Block 1, 2, 3 and 4 Retained)		4uA

Note

Please be aware that many factors can influence the overall power consumption measurements. The results given in the Table 1 are done in a specific laboratory characterization conditions.
