ON Semiconductor – Integrated HART modem IC: NCN5193 requires few external components


NCN5193: 1,200bits/s data rate


ON Semiconductor’s NCN5193 is a single-chip, CMOS modem for use in Highway Addressable Remote Transducer (HART) field instruments and masters.

The modem and a few external passive components provide all of the functions needed to meet the requirements of communication over the HART physical layer, including modulation, demodulation, receive filtering, carrier detect, and transmit-signal shaping.

In addition, the NCN5193 also has an integrated 16-bit DAC for implementing a current-loop slave transmitter. It uses phase continuous frequency-shift keying to communicate at a data rate of 1,200bits/s.

  • Compatible with 1.8V and 3.3V MCUs
  • Serial peripheral interface
  • Operating temperature range: -40°C to 85°C
