1 EBI timing specified at: VDDE = 1.6–3.6 V (unless stated otherwise); TA = TL to TH; and CL = 30 pF with DSC = 0b10.
2 Speed is the nominal maximum frequency. Max. speed is the maximum speed allowed including frequency modulation (FM).
82 MHz parts allow for 80 MHz system clock + 2% FM; 114 MHz parts allow for 112 MHz system clock + 2% FM; and
135 MHz parts allow for 132 MHz system clock + 2% FM.
3 The external bus is limited to half the speed of the internal bus.
4 Refer to fast pad timing in Table 17 and Table 18 (different values for 1.8 V and 3.3 V). 5 SIU_ECCR[EBTS] = 0 timings are tested and valid at VDDE = 2.25–3.6 V only; SIU_ECCR[EBTS] = 1 timings are tested and
valid at VDDE = 1.6–3.6 V.
