LS7366R-S 32-BIT QUADRATURE COUNTER WITH SERIAL INTERFACE IC

LS7366R-S 32-BIT QUADRATURE COUNTER WITH SERIAL INTERFACE IC

The LS7366R is a 32-bit CMOS counter, with direct interface for quadrature clocks from incremental encoders. It also interfaces with the index signals from incremental encoders to perform variety of marker functions. For communications with microprocessors or microcontrollers, it provides a 4-wire SPI/MICROWIRE bus. The four standard bus I/OS are SS/, SCK, MISO and MOSI. The data transfer between a microcontroller and a slave LS7366R is synchronous. The synchronization is done by the SCK clocks supplied by the microcontroller. Each transmission is organized in blocks of 1 to 5 bytes of data. A transmission cycle is Initiated by a high to low transition of the SS/ input. The first byte received in a transmission cycle is always an instruction byte, whereas the second through the fifth bytes are always interpreted as data bytes.
