Abstract:
A fingerprint sensor with programmable sensing patterns is disclosed in one embodiment of the invention as including a fingerprint sensing circuit having multiple I/O interconnects. The I/O interconnects are configured to sequentially drive a plurality of fingerprint sensing elements. A memory device may be operably coupled to the fingerprint sensing circuit. A programmable data structure, such as a table, file, character string, numeric value, array, or the like may be stored in the memory device to designate a pattern for driving the fingerprint sensing elements. The fingerprint sensing circuit is configured to drive the fingerprint sensing elements according to the designated pattern. In selected embodiments, the fingerprint sensing elements may include transmitting elements, receiving elements, or a combination thereof.
