SAM7S Series
USART: DCD is active High instead of Low
Voltage Regulator: Current Consumption in Deep Mode
Voltage Regulator: Load Versus Temperature
The transmitter may use the timeguard feature or send two STOP conditions. Only one STOP
condition is taken into account by the receiver state machine. After this STOP condition, as there
is no valid data, the receiver state machine will go in idle mode and enable the RXBRK flag.
The DCD signal is active at High level in the USART Modem Mode.
DCD should be active at Low level.
Add an inverter.
Current consumption in Deep Mode is maximum 60 µA instead of 25 µA.
Due to current rejection from VDDIN to VDDCORE, the current consumption in Deep Mode can-
not be guaranteed. Instead, 60 µA is guaranteed whatever the condition.
None.
Maximum load is 50 mA at 85 °C (instead of 100 mA).
Maximum load is 100 mA at 70°C.
None.
