UART Over Powerline Transceiver - ISL40 |
|
Datasheet
|
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. 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 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 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.
