Switching Characteristics
Over recommended operating supply and temperature ranges unless otherwise specified. (Note 2)
Recommended Input Timing Requirements
Over recommended operating supply and temperature ranges unless otherwise specified. (Note 2)
Note 1: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the device
should be operated at these limits. The tables of “Electrical Characteristics” specify conditions for device operation.
Note 2: Typical values are given for VDDIO = 1.8V and VDD = VDDA = 3.0V and T
Note 3: Current into a device pin is defined as positive. Current out of device pins is defined as negative. Voltages are referenced to Ground unless otherwise
specified.
Note 4: UFBGA assumes 4 layer PCB, LLP assumes 2 layer PCB for thermal calculations.
Note 5: This parameter is Guaranteed by Design (GBD) based on simulation or bench characterization.
Note 6: This parameter is guaranteed by a ATE tester delay, actual turn off time is faster.
Note 7: Typical supply condition is V
