PSWITCH MID LEVEL & STARTUP
PSWITCH HIGH LEVEL
Maximum Ambient Operating Temperature may be limited due to on-chip power dissipation. T
Assumes 6-layer PCB and still air. Actual thermal performance may vary based on board and enclosure composition and
design.
A MID LEVEL PSWITCH state can be generated by connecting the VDDXTAL output of the SOC to PSWITCH through a
switch.
PSWITCH acts like a high impedance input (>300 kΩ) when the voltage applied to it is less than 1.5V. However, above 1.5V
it becomes lower impedance. To simplify design, it is recommended that a 10 kΩ resistor to VDDIO be applied to PSWITCH
to set the HIGH LEVEL state (the PSWITCH input can tolerate voltages greater than 2.45 V as long as there is a 10 kΩ resistor
in series to limit the current).
