Freescale Semiconductor Advance Information
Document Number: MC33660 Rev 5.0, 10/2013
ISO K Line Serial Link Interface
The 33660 is a serial link bus interface device designed to provide bi-directional half-duplex communication interfacing in automotive diagnostic applications. It is designed to interface between the vehicle’s on-board microcontroller, and systems off-board the vehicle via the special ISO K line. The 33660 is designed to meet the Diagnostic Systems ISO9141 specification. The device’s K line bus driver’s output is fully protected against bus shorts and overtemperature conditions. The 33660 derives its robustness to temperature and voltage extremes by being built on a SMARTMOS process, incorporating CMOS logic, bipolar/MOS analog circuitry, and DMOS power FETs.
