Electrical Specification

3.5.1

Supply Voltage

The SMARC sAT30 module operates over an input voltage range of 3.1V to 5.25V. Power is provided from the carrier

through 10 power pins as defined by the SMARC specification.

Caution!

The SMARC specification states that the input voltage range should extend down to 3.0V. The sAT30 lower

limit

is determined by a non-volatile register setting in the TI PMU used.

3.5.2

RTC/Backup Voltage

3.0V RTC backup power is provided through the VDD_RTC pin from the carrier board. This connection provides back up

power to the module PMU.

3.5.3

No Separate Standby Voltage

The SMARC sAT30 does not have a standby power rail. Standby operation is powered through the main supply voltage

rail, as defined in the SMARC specification.

3.5.4

Module I/O Voltage

The SMARC sAT30 module complies with the default I/O voltage (1.8V) level defined by SMARC Hardware

specification. Module pin S158 (VDD_IO_SEL#) is tied low on the Module, per the SMARC specification, indicating a

1.8V I/O voltage level.
