56.2 Power Supply

Table 56-4. Power Supply Electrical Specifications
DC CHARACTERISTICS Standard Operating Conditions: VDD = AVDD = 1.71V to 3.63V (unless otherwise stated)

Operating temperature:

-40°C ≤ TA ≤ +125°C for Extended Temperature
Param. No. Symbol Characteristics Min. Typ. Max. Units Conditions
REG_45 VPOR Power-on Reset 0.97 — 1.65 V VDD Power up/Down (See Param REG_43, VDD Ramp Rate)
REG_47 VBOD33 (1,2) VDD BOD (All modes) 1.45 — 1.57 V

SUPC.BOD33.LEVEL[7:0] = 0x00 (Min Value) ,

SUPC.BOD33.HYST[3:0] = 0x02
1.60 — 1.72

SUPC.BOD33.LEVEL[7:0] = 0x19 (Recommended Value) ,

SUPC.BOD33.HYST[3:0] = 0x02
1.62 — 1.74

SUPC.BOD33.LEVEL[7:0] = 0x1C (Recommended Value) ,

SUPC.BOD33.HYST[3:0] = 0x02
2.93 — 3.32

SUPC.BOD33.LEVEL[7:0] = 0xFF (Max Value) ,

SUPC.BOD33.HYST[3:0] = 0x00
Note:
  1. VBOD(min) = (1.5 + (SUPC.BOD33.LEVEL[7:0] * VBOD33LEVEL_STEP))

    VBOD(max) = (VBOD(min) + (SUPC.BOD33.HYST[3:0] * VBOD33HYST_STEP))

  2. If a hysteresis value is programmed, the following equation must be respected to avoid any overflow on VBOD(max) : LEVEL[7:0] value < 255 - HYST[3:0] value.
