This product includes circuitry specifically designed for the protection of its internal devices from the damaging effects of excessive
static charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying greater than the rated maximum.
Parameters are valid over the operating temperature range unless otherwise specified. All voltages are with respect to V
otherwise noted.
Based on package heat transfer, not device power consumption.

6.6.9 Power-down mode
The SC18IS600/601 can be placed in a low-power mode where the internal oscillator is
stopped and it will no longer respond to SPI messages. Enter the Power-down mode by
sending the power-down command (0x30) followed by the two defined bytes, which are
0x5A followed by 0xA5. If the exact message is not received, the device will not enter the
power-down state.
Before entering the power-down state, WAKEUP/IO4 should be placed in a HIGH state.
To exit the power-down state, the WAKEUP/IO4 should be brought LOW. After leaving the
power-down state, the WAKEUP/IO4 can once again be used as a general-purpose IO
pin.
