GENERAL DESCRIPTION:

LS7366 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.

GENERAL FEATURES:

? Operating voltage: 3.0V to 5.5V (VDD - VSS)

? 5V count frequency: 40MHz

? 3V count frequency: 20MHz

? 32-bit counter (CNTR).

? 32-bit data register (DTR) and comparator.

? 32-bit output register (OTR).

? Two 8-bit mode registers (MDR0, MDR1) for programmable functional modes.

? 8-bit instruction register (IR).

? 8-bit status register (STR).

? Latched Interrupt output on Carry or Borrow or Compare or Index.

? Index driven counter load, output register load or counter reset.

? Internal quadrature clock decoder and filter.

? x1, x2 or x4 mode of quadrature counting.

? Non-quadrature up/down counting.

? Modulo-N, Non-recycle, Range-limit or Free-running modes of counting

? 8-bit, 16-bit, 24-bit and 32-bit programmable configuration synchronous (SPI) serial interface

? LS7366 (DIP); LS7366-S (SOIC); LS7366-TS (TSSOP)

SPI/MICROWIRE (Serial Peripheral Interface):

? Standard 4-wire connection: MOSI, MISO, SS/ and SCK.

? Slave mode only.
