iCE40 HX-Series Ultra-Low Power Family
Electrical Characteristics
All parameter limits are specified under worst-case supply voltage, junction temperature, and processing conditions.
Absolute Maximum Ratings
Stresses beyond those listed under Table 2 may cause permanent damage to the device. These are stress ratings only;
functional operation of the device at these or any other conditions beyond those listed under the Recommended
Operating Conditions is not implied. Exposure to absolute maximum conditions for extended periods of time
adversely affects device reliability.

Notes:
1. VPP_2V5 must be connected to a valid voltage, when the iCE40HX device is active.
2. VPP_FAST, used only for fast production programming, must be left floating or unconnected in application.
3. VCCPLL must be tied to VCC when PLL is not used.
