Since the 80's, ST has pioneered the market offering robust,
viable and cost-effective solutions for communication over
power lines.
Following the first power-line modems (ST7536 and ST7537),
new breakthrough transceivers have been designed using ST’s
sub-micron mixed-signal technologies and multi-segment design
experience.
Enel S.p.A., one of the largest electric utilities worldwide
has already integrated millions of ST power-line transceivers
in its digital meters in the Italian power network for remote
automatic meter reading and other functions.
With integrated an analog front end (AFE) and power-line
driver, the ST7538 and the new ST7540 are nowadays the most
integrated power-line transceivers available on the market.
They can be inserted into an existing static meter or home-appliance
main board by connecting them through the general-purpose
I/Os of the microcontroller which is responsible for handling
the upper layer of the communication protocol stack and
the application commands. more...
