LIN Communications
The DEMO908GZ60 implements a single Local Interconnect Network (LIN) interface on the
ESCI port. The LIN physical interface consists of a MC33661 transceiver at U5 and 2 4-
position Molex Mini-Fit connectors at CON1 and CON2. The LIN interface supports data
transmission speeds up to 20 kbps. The LIN interface is configured in a Master – Slave con-
figuration with a single master controlling multiple slaves.

CAN Communications
The DEMO908GZ60 implements a single Fault-Tolerant Controller Area Network (CAN) inter-
face. CAN is used to high-speed and fault-tolerant automotive networks. The CAN physical
interface consists of a MC33388 transceiver at U 4 and a single 3-position header. The trans-
ceiver converts serial data from the MCU to differential data for the CAN bus. The physical
layer implemented supports data rates up to 125 kbps. The differential bus termination voltage
is provided by the physical interface. The figure below details the pin-out of the CAN bus con-
nector.

MON08 Communications
The DEMO908GZ60 provides 2 methods for accessing the internal monitor. Serial MON08
access is provided through the COM port. A MON08 compatible programming pod may also
attach to the 14-pin MON08 port. Monitor mode is enabled by the COM_Mode, MON_EN, and
VTST_EN option jumpers. Some MON08 pods can supply VTST directly eliminating the need
