Abstract
A slave device includes: a serial communications slave having an address designated for performing serial communications with a master; a single address determination pin configured to be, selectively, connected to a power terminal without being connected to a first external resistor, connected to a ground terminal without being connected through a second external resistor, connected to the power terminal through the first external resistor, or connected to the ground terminal through a second external resistor; and an address allocator configured to designate the address of the serial communications slave based on a plurality of state bits determined depending on a connection state of the single address determination pin.
