The section provides information about the AC characteristics and timing of the
eZ80F91 device. All AC timing information assumes a standard load of 50 pF on
all outputs. See Table 234.
All data is preliminary and subject to change following completion of production
characterization.
Table 235 shows simulated inductance, capacitance, and resistance results for
the 144-pin LQFP package at 100 MHz operating frequency.
