Pad AC Specifications

2 For maximum flash performance, this should be set to 0b11.

3 For maximum flash performance, this should be set to 0b110.

4 For maximum flash performance, this should be set to 0b1.

5 This setting allows for 100 MHz system clock with 2% frequency modulation.

6 This setting allows for 128 MHz system clock with 2% frequency modulation.

Table 17. Pad AC Specifications (VDDEH = 5.0V, VDDE = 1.8V)1

1 These are worst case values that are estimated from simulation and not tested. The values in the table are simulated at

FSYS = 132MHz, VDD = 1.35V to 1.65V, VDDE = 1.62V to 1.98V, VDDEH = 4.5V to 5.5V, VDD33 and VDDSYN = 3.0V to 3.6V,

TA = TL to TH.

2 This parameter is supplied for reference and is not guaranteed by design and not tested.

3 Out delay is shown in Figure 3. Add a maximum of one system clock to the output delay for delay with respect to system clock.

4 Delay and rise/fall are measured to 20% or 80% of the respective signal.
