US Digital 32-bit Quadrature Counter with Serial Interface LFLS7366R-S

The LSI Computer Systems LFLS7366R-S is a 32-bit CMOS counter with a direct interface to quadrature signals from incremental encoders. It also interfaces with the index signals from incremental encoders to perform a variety of marker functions. A 4-wire SPI/MICROWIRE bus is used for communication with a host microprocessor.
