Notes:
1. AC test load = 50 pF for XCF01S/XCF02S/XCF04S; 30 pF for XCF08P/XCF16P/XCF32P.
2. Float delays are measured with 5 pF AC loads. Transition is measured at 200 mV from steady-state active levels.
3. All AC parameters are measured with V = 0.0V and V = 3.0V.

8. CF, EN_EXT_SEL, REV_SEL[1:0], and BUSY are inputs for the XCFxxP PROM only.
9. When JTAG CONFIG command is issued, PROM drives CF Low for at least the T
minimum.
