The ISL40 is an innovative VLSI solution for low cost network of I/O peripheral devices communicating
over a noisy single wire or a battery power line using the LIN protocol. It provides the means for an
economical network of multiple slave devices for applications as controlling motors, reading sensors
etc., eliminating the need for a dedicate controller for slave modules.
The device operates as an independent LIN slave in a network controlled by a SIG40 master device,
which transmits five types of messages to each one of its slaves; Read, Read Change, Write, Sleep
and Change Frequency.
The ISL40 slave device identifies a LIN message addressed to its predefined ID. When a Write
message is received, the data part of the message is directed to the corresponding 4 or 8 output pins.
When a Read or Read Change message is detected, the slave responds with a LIN2.0 message that
contains information on all its 8 inputs or 4 input pins and 4 output pins.
A Sleep command enables power saving. Wakeup messages awaken remote devices.
The device is based on an original multiplex signaling technology. The ISL40 has a LIN message
handler, a unique signaling modem and coder/decoder that overcome the hostile communication
environment over vehicle battery lines.
The ISL40 capability of communicating over battery-powered line is useful for a wide range of vehicular
and industrial applications, such as doors, seats, mirrors, climate control, lights etc.
The ISL40 device operates as an independent slave in a network controlled by a SIG40 master device
that can transmit asynchronous LIN messages to any one of its 15 slave devices. An ISL40 slave device
which identifies a Write message addressed to its ID, takes the data part of the message and outputs it
to its output pins, while a master Read message is responded by the slave with a message consisting of
its sampled input pins. The device receives and transmits special narrow band signaling carrier, which
can be differentiated from noise. The receiver receives the signaling patterns, extracting them into the
original bits. The rest of the spectrum is reserved for additional communication channels over the same
DC noisy lines.
