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 

- 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.

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

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.
