Forum: µC & Digital Electronics SAM7S Low Power Design Suggestion

Hi all.

I am trying to minimize the AT91SAM7S64 MCU power consumption. I 
measured the MCU consumes around 15mAH Current which is very high for 
3.7V Li-Poly Battery Power Device.

Can anyone advise the basic Schematic idea to design a low power Board 
... by minimizing the Current Consumption?

My Target is to fix the current consumption within 1mAH, where I need to 
use:

- Three ADC (AD4, AD5, AD6).
- Two UART (UART0 and UART1)
- Few GPIO's (LED and PushButtons)
- USB or RS232 SAM-BA (for only Firmware Update)

Is it possible using SAM7S64?

Thanks in advance.

Regards.
Sakibnaz.

I believe the datasheet provides achapter about this subject...

Hi.

I checked the datasheet of SAM7S, and found "Running out of SRAM" can 
reduce Power Consumption.

Can you please advice how to achieve or enable "Running out of SRAM"?

Thank you.

Sakibnaz.
