Power consumption reduction at different modes
Currently I am using CY8C29466-24PXI to develope a device which wakes up in a short time interval and goes into sleep modes for most of the time. After reading a related application note: AN47310. I have got a brief idea how I should implement the sleep mode with different modifiers. After doing several test, this is the amount of current draw by the development board (I am using CY3210-PSoCEval1 so the current drawn by LED and voltage regulator are also included):
Operating mode: ~26mA
Sleep mode (No other configurations): ~23mA
Sleep mode with sleep timer activated: 15mA~17mA
Sleep mode with sleep timer activated (Sleep timer API used): 23mA
Sleep mode (With all configured modifiers and sleep mode is inactivated): ~9mA
So I do not know how I should utilise the sleep timer module whilst minimising power consumption. So far as I observed, the PSoC does not reduce much energy with activated sleep timer module? Also, the system halts and some point when I implement sleep timer API, I have no idea how should overcome this.
Enclosed please find my project file. I used the example code from AN47310 and modifed it for my own purpose.
Any ideas/assistance are much appreciated. Thank you very much!
