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.
