PIC10(L)F320/322
13.0 INTERNAL VOLTAGE
REGULATOR (IVR)
The Internal Voltage Regulator (IVR), which provides
operation above 3.6V is available on:
•PIC10(L)F320
•PIC10(L)F322
This circuit regulates a voltage for the internal device
logic while permitting the V
DD and I/O pins to operate
at a higher voltage. When V
DD approaches the
regulated voltage, the IVR output automatically tracks
the input voltage.
The IVR operates in one of three power modes based
on user configuration and peripheral selection. The
operating power modes are:
-High
-Low
- Power Save Sleep mode
Power modes are selected automatically depending on
the device operation, as shown in Tabl e 1 3- 1. Tracking
mode is selected automatically when V
DD drops below
the safe operating voltage of the core.
TABLE 13-1: IVR POWER MODES - REGULATED
Note: IVR is disabled in Tracking mode, but will
consume power. See Section 24.0
“Electrical Specifications” for more
information.
