Voltage regulator
The regulator has five operating modes:
●
Regulator ON
–
Main regulator mode (MR)
–
Low power regulator (LPR)
–
Power-down
●
Regulator OFF
–
Regulator OFF/internal reset ON
–
Regulator OFF/internal reset OFF
Regulator ON
The regulator ON modes are activated by default on LQFP packages.On WLCSP66
package, they are activated by connecting both REGOFF and IRROFF pins to VSS, while
only REGOFF must be connected to VSS on UFBGA176 package (IRROFF is not available).
VDD minimum value is 1.8 V
(a).
There are three regulator ON modes:
●
MR is used in nominal regulation mode (Run)
●
LPR is used in Stop mode
●
Power-down is used in Standby mode:
The regulator output is in high impedance: the kernel circuitry is powered down,
inducing zero consumption (but the contents of the registers and SRAM are lost).
Regulator OFF
●
Regulator OFF/internal reset ON
On WLCSP66 package, this mode is activated by connecting REGOFF pin to VDD and
IRROFF pin to VSS. On UFBGA176 package, only REGOFF must be connected to VDD
(IRROFF not available).
The regulator OFF/internal reset ON mode allows to supply externally a 1.2 V voltage
source through VCAP_1 and VCAP_2 pins, in addition to VDD.
The following conditions must be respected:
–VDD should always be higher than VCAP_1 and VCAP_2 to avoid current injection
between power domains.
–
If the time for VCAP_1 and VCAP_2 to reach 1.08 V is faster than the time for VDD to
reach 1.8 V(a), then PA0 should be connected to the NRST pin (see Figure 6).
a.
VDD/VDDA minimum value of 1.65 V is obtained when the device operates in a reduced
temperature range.
