STN1110-I/MM

The STN1110-I/MM is a compact, cost-effective OBD-II (On-Board Diagnostics) interpreter IC from STMicroelectronics. It decodes vehicle diagnostic data (e.g., engine codes, live sensor readings) via standard protocols (CAN, ISO, KWP, etc.) and outputs them in a user-friendly ASCII format.
Key features:
- Supports SAE J1850, ISO 9141, ISO 14230 (KWP2000), and CAN (ISO 15765-4).
- Built-in UART interface for easy microcontroller communication.
- Low power consumption (3.3V or 5V operation).
- Small 10-pin DFN package (3x3mm), ideal for space-constrained designs.
Commonly used in OBD-II scanners, telematics, and automotive diagnostics tools, it simplifies access to vehicle data without complex firmware.
For detailed specs, refer to the STN1110 datasheet.
