Over Recommended Operating Conditions

Table 3.1. Absolute Maximum Ratings

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.

Table 3.2. Recommended Operating Conditions

Notes:

1. For correct operation, all supplies except VREF must be held in their valid operation range. This is true independent of feature usage.

2. All supplies with same voltage, except SERDES Power Supplies, should be connected together.

• 1. See recommended voltages by I/O standard in Table 3.4.
• 1. VCCAUX ramp rate must not exceed 30 mV/μs during power-up when transitioning between 0 V and 3 V.
• 1. Refer to ECP5 and ECP5-5G SERDES/PCS Usage Guide (FPGA-TN-02206) for information on board considerations for SERDES power supplies.
• 1. VCCHRX is used for Rx termination. It can be biased to Vcm if external AC coupling is used. This voltage needs to meet all the HDin input voltage level requirements specified in the Rx section of this Data Sheet.
