GENERAL DESCRIPTION:

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.

GENERAL FEATURES:

• Operating voltage: 3V 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

• LS7366R (DIP), LS7366R-S (SOIC), LS7366R-TS (TSSOP)

SPI/MICROWIRE (Serial Peripheral Interface):

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

• Slave mode only.
