Table 8. Characteristics of IC supply voltage …continued
T_amb = 25 °C; all parameters remain within limits but are only statistically tested for the temperature range; f_xtal = 10 MHz; all
currents flowing into the IC are positive; unless otherwise specified. Parameters specified as a function of
V_DD(INTF), V_DDI(REG), V_DD(INTREGD) or V_CC refer to the actual value at the time of measurement.
