Absolute Maximum Conditions
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.

2. 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.
3. All clock outputs loaded with 6" 60
4. The CY28312B-2 contains an internal crystal load capacitor between pin X1 and ground and another between pin X2 and ground. Total load placed on crystal
5. X1 input capacitance is applicable when driving X1 with an external clock source (X2 is left unconnected).
