2.4.2
The speed of the flash devices is not highly dependent upon the supply voltage. However, by limiting the
temperature range, the speed can be increased. The minimal guaranteed speed as a function of the supply voltage
and maximal temperature operating temperature is given in Figure 2-4.
2.4.3
For the ROM version, two possible operating modes exist: with and without voltage regulator. Using the voltage
regulator, a low power consumption will be obtained even with supply voltages above 2.4V. Without the voltage
regulator (i.e. VREG short-circuited to VBAT) , a higher speed can be obtained.
