The KIT33660 Evaluation board supports the MC33660, which 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 MC33660 is designed to meet the Diagnostic System ISO9141 specification. The device’s K line bus driver’s output is fully protected against bus shorts and over-temperature conditions.

The evaluation board comes with an on-board 5.0 V source via a zener diode with a resistor in series, to optionally provide Chip Enable (CEN) and/or VDD input voltage by a simple jumper and three-position switch configuration. Transitioning from Normal to Sleep mode and vice versa is made simple with a three-position switch. The status of VBB, VDD, and CEN can be visually monitored via on-board LEDs. The ISO Bus signal is provided through a terminal block connector with simple slave or master configuration via jumper settings.

An isolated terminal block connector is implemented for the user to provide power to the board with an external DC power supply. TX and RX signals are routed on a separate terminal block connector and the user has the option to connect an external DC power supply for CEN and VDD for greater system flexibility.

Applications: Farm Equipment, Automotive Systems, Industrial Equipment, Robotic Equipment, Marine and Aircraft Networks
