Absolute Maximum Ratings
| Symbol | Description | XCF01S, XCF02S,
XCF04S | XCF08P, XCF16P, XCF32P | Units |
| VCCINT | Internal supply voltage relative to GND | –0.5 to +4.0 | –0.5 to +2.7 | V |
| VCCO | I/O supply voltage relative to GND | –0.5 to +4.0 | –0.5 to +4.0 | V |
| VCCJ | JTAG I/O supply voltage relative to GND | –0.5 to +4.0 | –0.5 to +4.0 | V |
| VIN | Input voltage with respect to
GND | VCCO < 2.5V | –0.5 to +3.6 | –0.5 to +3.6 | V |
| VCCO ≥ 2.5V | –0.5 to +5.5 | –0.5 to +3.6 | V |
| VTS | Voltage applied to High-Z
output | VCCO < 2.5V | –0.5 to +3.6 | –0.5 to +3.6 | V |
| VCCO ≥ 2.5V | –0.5 to +5.5 | –0.5 to +3.6 | V |
| TSTG | Storage temperature (ambient) | –65 to +150 | –65 to +150 | °C |
| TJ | Junction temperature | +125 | +125 | °C |
Notes:
1. Maximum DC undershoot below GND must be limited to either 0.5V or 10 mA, whichever is easier to achieve. During transitions, the device pins can undershoot to –2.0V or overshoot to +7.0V, provided this overshoot or undershoot lasts less then 10 ns and with the forcing current being limited to 200 mA.
2. Stresses beyond those listed under Absolute Maximum Ratings might cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those listed under Operating Conditions is not implied. Exposure to Absolute Maximum Ratings conditions for extended periods of time adversely affects device reliability.

Supply Voltage Requirements for Power-On Reset and Power-Down
| Symbol | Description | XCF01S, XCF02S,
XCF04S | XCF08P, XCF16P,
XCF32P | Units |
| Min | Max | Min | Max |
| TVCC | VCCINT rise time from 0V to nominal voltage(2) | 0.2 | 50 | 0.2 | 50 | ms |
| VCCPOR | POR threshold for the VCCINT supply | 1 | - | 0.5 | - | V |
| TOER | OE/RESET release delay following POR(3) | 0.5 | 3 | 0.5 | 30 | ms |
| VCCPD | Power-down threshold for VCCINT supply | - | 1 | - | 0.5 | V |
| TRST | Time required to trigger a device reset when the VCCINT supply drops below the maximum VCCPD threshold | 10 | - | 10 | - | ms |
Notes:
1. VCCINT, VCCO, and VCCJ supplies can be applied in any order.
2. At power up, the device requires the VCCINT power supply to monotonically rise to the nominal operating voltage within the specified TVCC rise time. If the power supply cannot meet this requirement, then the device might not perform power-on-reset properly.
3. If the VCCINT and VCCO supplies do not reach their respective recommended operating conditions before the OE/RESET pin is released, then the configuration data from the PROM is not available at the recommended threshold levels. The configuration sequence must be delayed until both VCCINT and VCCO have reached their recommended operating conditions.
