Maximum condition for tpr, tpo, tpi, and tpv: wcs model, 1.1 V, I/O 3.0 V, and 105 °C. Minimum condition for tpr, tpo, and tpv:
bcs model, 1.3 V, I/O 3.6 V 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, 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, and –40 °C.
Maximum condition for tpi and trfi: wcs model, 1.1 V, I/O 3.0 V and 105 °C. Minimum condition for tpi and trfi: bcs model, 1.3 V,
I/O 3.6 V and –40 °C. Input transition time from pad is 5 ns (20%–80%).
