Description
Xilinx introduces the Platform Flash series of in-system programmable configuration PROMs. Available in 1 to 32 Megabit (Mbit) densities, these PROMs provide an easy-to-use, cost-effective, and reprogrammable method for storing large Xilinx FPGA configuration bitstreams. The Platform Flash PROM series includes both the 3.3V XCFxxS PROM and the 1.8V XCFxxP PROM. The XCFxxS version includes 4-Mbit, 2-Mbit, and 1-Mbit PROMs that support Master Serial and Slave Serial FPGA configuration modes (Figure 1). The XCFxxP version includes 32-Mbit, 16-Mbit, and 8-Mbit PROMs that support Master Serial, Slave Serial, Master SelectMAP, and Slave SelectMAP FPGA configuration modes (Figure 2).

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:
- 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 over- or undershoot lasts less then 10 ns and with the forcing current being limited to 200 mA.
- 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.
