Notes:

1. VDDD, VDDA =3.3 V.

2. VDDD, VDDA =5.25V.

3. IBAT = current from VBAT (the large negative supply). For a switched-mode power supply regulator efficiency of 71%,

the user can calculate the regulator current consumption as IBAT x VBAT/(0.71 x VDC).

VDDA =VDDA = 3.13 to 5.25 V, TA = 0 to 70 °C for F-Grade, –40 to 85 °C for G-Grade, CL =20pF)

Notes:

1. All timing (except rise and fall time) is referenced to the 50% level of the waveform. Input test levels are

VIH =VD – 0.4 V, VIL = 0.4 V. Rise and fall times are referenced to the 20% and 80% levels of the waveform.

2. Additional initialization guidelines apply; see section 1.2 ProSLIC Initialization in AN35.
