TIDM-HAHSCPTO

High Availability High Speed Counter (HSC) and Pulse Train Output (PTO) Reference Design

TIDM-HAHSCPTO

Design files

Overview

This reference design provides firmware and test platform for two different industrial input/output functions related to motion control: high-speed counter (HSC) and pulse-train output (PTO). The design is based on a microcontroller platform that is suitable for use in industrial applications where high availability and/or functional safety are important requirements.

Features
  • High-speed (up to 400 KHz) 32-bit HSC counter with two-counter input pins, four-auxiliary input pins, two-input capture registers and two-compare output pins
  • PTO generates output pulse trains and trapezoidal profiles up to 100 KHz with 9.1-ns resolution
  • Count/Dir, clockwise/counter-clockwise and quadrature modes
  • Reduces CPU load and interrupt latency requirements by operating autonomously on N2HET-timing coprocessor
  • Reduces system cost by replacing FPGA or ASIC
  • Includes N2HET firmware and test platform as well as host CPU-driver functions
