The PIC operates from a 2.0 V to 5.5 V supply and, as listed in the textbook, draws 220 at 4 MHz, 11 at 32 KHz and about 50 nA in standby.
In its feature overview the textbook specifies the PIC's electrical operating limits. The device works over a wide supply-voltage range of 2.0 V to 5.5 V, which lets it run from batteries or regulated supplies. Its current consumption depends on the clock speed: about 220 at 2.0 V with a 4 MHz clock, dropping to 11 at 2.0 V with a 32 KHz clock, and only around 50 nA in the power-saving standby (sleep) mode. The wide voltage range and very low standby current make the PIC well suited to low-power, battery-operated appl …
