STN1110 Multiprotocol OBD II to UART Interpreter

Quick Overview

STN1110 is a multiprotocol OBD to UART interpreter (OBD chip) that supports all OBD-II protocols, and is fully compatible with the ELM327 command set, while outperforming the original ELM327 IC in every category: stability, performance, features, and price. 


Product Description

STN1110

Overview

On-Board Diagnostics, Second Generation (OBD-II) is a set of standards for implementing a computer based system to control emissions from vehicles. It was first introduced in the United States in 1994, and became a requirement on all 1996 and newer US vehicles. Other countries, including Canada, parts of the European Union, Japan, Australia, and Brazil adopted similar legislation. A large portion of the modern vehicle fleet supports OBD-II or one of its regional flavors.

Among other things, OBD-II requires that each compliant vehicle be equipped with a standard diagnostic connector (DLC) and describes a standard way of communicating with the vehicle’s computer, also known as the ECU (Electronic Control Unit). A wealth of information can be obtained by tapping into the OBD bus, including the status of the malfunction indicator light (MIL), diagnostic trouble codes (DTCs), inspection and maintenance (I/M) information, freeze frames, VIN, hundreds of real-time parameters, and more.

STN1110 is an OBD to UART interpreter that can be used to convert messages between any of the OBD-II protocols currently in use, and UART. It is fully compatible with the de facto industry standard ELM327 command set. Based on a 16-bit processor core, the STN1110 offers more features and better performance than any other ELM327 compatible IC.

Feature Highlights

  • Fully compatible with the ELM327 AT command set
  • Extended ST command set
  • UART interface (baud rates from 38 bps to 10 Mbps)
  • Secure bootloader for easy firmware updates
  • Support for all legislated OBD II protocols:
    • ISO 15765-4 (CAN)
    • ISO 14230-4 (Keyword Protocol 2000)
    • ISO 9141-2 (Asian, European, Chrysler vehicles)
    • SAE J1850 VPW (GM vehicles)
    • SAE J1850 PWM (Ford vehicles)
  • Support for non-legislated OBD protocols:
    • ISO 15765
    • ISO 11898 (raw CAN)
  • Support for SAE J1939 OBD protocol
  • Superior automatic protocol detection algorithm
  • Large memory buffer
  • Voltage input for battery monitoring
  • Available in SPDIP, SOIC and QFN-S packages
  • RoHS compliant
