Absolute Maximum Ratings[4]
Stresses greater than those listed in this table may cause
permanent damage to the device. These represent a stress
rating only. Operation of the device at these or any other condi-
tions above those specified in the operating sections of this
specification is not implied. Maximum conditions for extended
periods may affect reliability.

Notes:
4. Multiple Supplies: The voltage on any input or I/O pin cannot exceed the power pin during power-up. Power supply sequencing is NOT required.
5. CY24242 logic inputs have internal pull-up resistors.
6. X1 input threshold voltage (typical) is VDDQ/2.
7. The CY24242 contains an internal crystal load capacitor between pin X1 and ground and another between pin X2 and ground. Total load placed on crystal is
14 pF; this includes typical stray capacitance of short PCB traces to crystal.
8. X1 input capacitance is applicable when driving X1 with an external clock source (X2 is left unconnected).
