Hi all.

I am trying to minimize the AT91SAM7S64 MCU power consumption. I
measured the MCU consumes around 30mAH.

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 SAM-BA (for only Firmware Update)

I found at Datasheet by "Running Out Of SRAM" Power Consumption can be reduced a lot.

- Can anyone please suggest how to achieve "Running Out Of SRAM"?

- Or any other Schematic Design Consideration to reduce Power Consumption?

Thanks in advance.

Regards.
