HT1200M HART Communication Controller

HT1200M

Product Overview

The HT1200M communication controller is a single-chip, low-power controller with full independent intellectual property rights and 100% domestic localization. When combined with external passive components, it provides all functions required to meet HART physical layer requirements, including modulation, demodulation, receive filtering, carrier detection, and transmit signal shaping. It is widely used in various products such as transmitters, smart measurement devices, and instruments.

  • Simple and convenient design:Integrating a full-featured, HART compliant FSK modem, it requires no complex design, just a few external components, to quickly achieve HART communication, greatly simplifying development and lowering production costs.
  • Flexible and diverse configuration:It supports multiple clock configuration methods, allowing either an external crystal oscillator or an external clock input, flexibly adapting to design requirements in different scenarios and enhancing product application compatibility and flexibility.
  • Industrialgrade reliable design:Designed to industrial-grade standards, it operates over a temperature range of -40°C to +85°C, enabling stable performance in various harsh industrial environments and ensuring continuous and reliable operation of the chip under complex working conditions.
  • Reliable control of proprietary intellectual property:The controller has fully independent intellectual property rights, with the entire process from wafer manufacturing to packaging and testing completed domestically. This effectively mitigates supply chain risks and ensures stable chip availability and controllable supply.
  • Wide voltage compatibility:Supporting a wide 3.3V–5V operating range, the chip adapts to different industrial power supply scenarios, eliminating the need for extra voltage conversion circuits and improving compatibility and convenience.
  • Wide range of package types:Supporting both LQFP32 and QFN32 packages, it offers flexible choices for different product designs and space constraints, making it suitable for a wide range of applications.
