Note:

1. Maximum condition for tpr, tpo, tpi, and tpv: wcs model, 1.1 V, I/O 1.65 V, and 105 °C. Minimum condition for tpr, tpo, and tpv:

bcs model, 1.3 V, I/O 1.95 V and –40 °C. Input transition time from core is 1 ns (20%–80%).

2. Minimum condition for tps: wcs model, 1.1 V, I/O 1.65 V, and 105 °C. tps is measured between VIL to VIH for rising edge and

between VIH to VIL for falling edge.

3. Maximum condition for tdit: bcs model, 1.3 V, I/O 1.95 V, and –40 °C.

4. Maximum condition for tpi and trfi: wcs model, 1.1 V, I/O 1.65 V and 105 °C. Minimum condition for tpi and trfi: bcs model, 1.3 V,

I/O 1.95 V and –40 °C. Input transition time from pad is 5 ns (20%–80%).
