1. Stress above those listed under the “Absolute Maximum Ratings” may cause permanent damage to the device. Functional
operation of the device at these or any other conditions above those indicated in the operational sections of this specification
is not implied.
2. Compliance with Lattice Thermal Management document is required.
3. All voltages referenced to GND.
4. Undershoot of -2V and overshoot of (V IH (MAX) + 2V), up to a total pin voltage of 6.0V, is permitted for a duration of < 20ns.
5. Maximum of 64 I/Os per device with VIN > 3.6V is allowed.

1. Insensitive to sequence of V CC or V CCO. However, assumes monotonic rise/fall rates for V CC and V CCO, provided (V IN - V CCO ) ? 3.6V.
2. 0 < V CC < V CC (MAX), 0 < V CCO < V CCO (MAX).
3. I DK is additive to I PU , I PD or I BH . Device defaults to pull-up until fuse circuitry is active.
