STN1110-IMM
General Description
The STN1110-IMM is a multiprotocol OBD-II to UART interpreter integrated circuit designed for automotive diagnostic, telematics, and vehicle communication applications. The device translates OBD-II network traffic into a UART serial data stream for communication with external microcontrollers, embedded processors, and host systems. It supports all legislated OBD-II protocols and provides compatibility with ELM327-based software while offering enhanced processing performance, expanded memory resources, advanced message filtering, firmware upgrade capability, and low-power operation. The device is intended for use in automotive diagnostic tools, fleet management systems, vehicle monitoring equipment, data acquisition systems, and embedded automotive communication products.
