Notes:

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 the Lattice Thermal Management document is required.

3. All voltages referenced to GND.

4. Undershoot and overshoot of -2V to (VIHMAX +2) volts is permitted for a duration of <20ns.

1. If VCCIO or VCCJ is set to 2.5V, they must be connected to the same power supply as VCCAUX.

2. See recommended voltages by I/O standard in subsequent table.

3. When VTT termination is not required, or used to provide the common mode termination voltage (VCMT), these pins can be left unconnected

on the device.

4. VCC12 cannot be lower than VCC at any time. For 1.2V operation, it is recommended that the VCC and VCC12 supplies be tied together with

proper noise decoupling between the digital VCC and analog VCC12 supplies.

5. VCC, VCCIO (all banks), VCC12 and VCCJ must reach their minimum values before conﬁguration will proceed.

6. If VCCIO for a bank is nominally 1.2V/1.5V/1.8V, then VCCAUX must always be higher than VCCIO during power up.
