SPI Flash power down current
We have an existing custom board that uses 14583. We have replaced the 14583 with the 14586 and all other circuitry is the same. The problem that we are having is that we are not able to reduce our current consumption to the values in the 14583
In our design we have an LCD whose enable pin is set on Port 2 Pin 3, which is also used by as SPI_EN_GPIO_PORT by the SPI FLASH. In our 14583 chip when we are about to go to sleep then set this Pin to Output low in order to turn off the power to the LCD and as a result our current consumption would be around 38uA in sleep mode.
