FEATURES
:● 30 MHz count frequency in non-quadrature mode, 17MHz in x4 quadrature mode.
● Dual 24-bit counters to support X and Y axes in motion control applications.
● Dual 24-bit comparators.
● Digital filtering of the input quadrature clocks
● Programmable 8-bit separate filter clock prescalers for each axis.
● Error flags for noise exceeding filter band width.
● Programmable Index Input and other programmable I/Os.
● Independent mode programmability for each axis.
● Programmable count modes: Quadrature (x1, x2, x4) / Non-quadrature, Normal / Modulo-N / Range Limit / Non-Recycle, Binary / BCD.
● 8-bit 3-State data I/O bus.
● 5V operation (VDD-VSS).
● TTL/CMOS compatible I/Os.
● LS7266R1 (DIP); LS7266R1-SD (Skinny DIP); LS7266R1-S (SOIC); LS7266R1-TS (TSSOP) LS726 6R1 V SS (GND) 12 C/D 13 WR 14 LS7266R1 Registers: LS7266R1 has a set of registers associated with each X and Y axis. All X-axis registers have the name prefix X, whereas all Y-axis registers have the prefix Y. Selection of a specific register for Read/Write is made from the decode of the three most significant bits (D7-D5) of the data-bus.
