87 / 210 page ![]() 2011 Microchip Technology Inc. Preliminary DS41585A-page 87 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 VDD and I/O pins to operate at a higher voltage. When VDD 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 Table 13-1. Tracking mode is selected automatically when VDD 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. VREGPM1 Bit Sleep Mode Memory Bias Power Mode IVR Power Mode x No EC Mode or INTOSC = 16 MHz (HP Bias) High INTOSC = 1 to 8 MHz (MP Bias) INTOSC = 31 kHz to 500 kHz (LP Bias) Low 0 Yes Don’t Care Low 1Yes No HFINTOSC Power Save(1) No Peripherals Note 1: Forced to Low-Power mode by any of the following conditions: • BOR is enabled • HFINTOSC is an active peripheral source • Self-write is active • ADC is in an active conversion |
