Over recommended operating conditions.

Table 4.5. DC Electrical Characteristics

Notes:

• 1. Input or I/O leakage current is measured with the pin configured as an input or as an I/O with the output driver tri-stated. It is not measured with the output driver active. Internal pull-up resistors are disabled.
• 1. T^J 25 ^oC, f = 1.0 MHz.
• 1. Refer to VIL and VIH in Table 4.13.
• 1. Input pins are clamped to VCCIO and GND by a diode. When input is higher than VCCIO or lower than GND, the Input Leakage current will be higher than the IIL and IIH.

Table 4.1. Absolute Maximum Ratings

Notes:

• 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.
• Compliance with the Thermal Management document is required.
• All voltages referenced to GND.

Table 4.2. Recommended Operating Conditions

Notes:

• 1. Like power supplies must be tied together if they are at the same supply voltage and they meet the power up sequence requirement. See the Power-up Supply Sequence section. VCC and VCCPLL are recommended to be tied together to the same supply with an RC-based noise filter between them. Refer to iCE40 Hardware Checklist (FPGA-TN-02006).
• 1. See recommended voltages by I/O standard in subsequent table.
• 1. VCCIO pins of unused I/O banks should be connected to the VCC power supply on boards.
• 1. VPP_2V5 can, optionally, be connected to a 1.8 V (+/–5%) power supply in Slave SPI Configuration modes subject to the condition that none of the HFOSC/LFOSC and RGB LED driver features are used. Otherwise, VPP_2V5 must be connected to a power supply with a minimum 2.30 V level.
