Maximum condition for tpr, tpo, and tpv: wcs model, 1.1 V, I/O 3.0 V (3.0–3.6 V range) or 1.65 V (1.65–1.95 V range), and 105
°C. Minimum condition for tpr, tpo, and tpv: bcs model, 1.3 V, I/O 3.6 V (3.0–3.6 V range) or 1.95 V (1.65–1.95 V range), and
–40 °C. Input transition time from core is 1 ns (20%–80%).
Minimum condition for tps: wcs model, 1.1 V, I/O 3.0 V (3.0–3.6 V range) or 1.65 V (1.65–1.95 V range), and 105 °C. tps is
measured between VIL to VIH for rising edge and between VIH to VIL for falling edge.
Maximum condition for tdit: bcs model, 1.3 V, I/O 3.6 V (3.0–3.6 V range) or 1.95 V (1.65–1.95 V range), and –40 °C.
Maximum condition for tpi and trfi: wcs model, 1.1 V, I/O 3.0 V (3.0–3.6 V range) or 1.65 V (1.65–1.95 V range), and 105 °C.
Minimum condition for tpi and trfi: bcs model, 1.3 V, I/O 3.6 V or 1.95 V (1.65–1.95 V range), and –40 °C. Input transition time
from pad is 5 ns (20%–80%).
Hysteresis mode is recommended for input with transition time greater than 25 ns.
