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 VIL = 0.0V and VIH = 3.0V.
4.
If THCE High < 2 s, TCE = 2 s.
5.
If THOE Low < 2 s, TOE = 2 s.
6.
This is the minimum possible TCYC. Actual TCYC = TCAC + FPGA Data setup time. Example: With the XCF32P in serial mode with VCCO at
3.3V, if FPGA data setup time = 15 ns, then the actual TCYC = 25 ns +15 ns = 40 ns.
7.
Guaranteed by design; not tested.
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 THCF minimum.
