Figure 2-5. Supply configuration for ROM circuit operation by-passing the internal regulator.
Figure 2-6. Guaranteed speed as a function of supply voltage and for two temperature ranges when VREG=VBAT.
Important Note
Note that the acquisition chain will not operate if VBAT is below 2.4V. The internal reference voltage for the LCD
will not operate below 1.5V. If the internal reference is not used, the LCD voltage generator and the LCD driver will
operate down to 1.2V. The operation range of the different blocks is summarized in Figure 2-7.
