1 EBI timing specified at V

DD = 1.35–1.65 V, VDDE = 1.6–3.6 V (unless stated otherwise),

VDD33 and VDDSYN = 3.0–3.6 V, TA = TL to TH, and CL = 30 pF with DSC = 0b10.

2 The external bus is limited to half the speed of the internal bus.

3 Refer to fast pad timing in Table 17 and Table 18 (different values for 1.8 V and 3.3 V).

4 The EBTS = 0 timings are tested and valid at V

DDE = 2.25–3.6 V only,

whereas EBTS = 1 timings are tested and valid at VDDE = 1.6–3.6 V.

5 The EBTS = 0 timings are tested and valid at V

DDE = 2.25–3.6 V only,

whereas EBTS = 1 timings are tested and valid at VDDE = 1.6–3.6 V.
