MicroFIP is designed to collect data over WorldFIP directly from I/Os,
as well as locally processed data. The MicroFIP provides all the key
functions to transmit information across WorldFIP. It is produced by the
MICROFIP component is an ASIC solution implementing the WorldFIP
protocol, to be used in field devices able to communicate at the three
standard speeds: 31.25 kbits/s, 1 Mbit/s, 2.5 Mbits/s. In addition its
static implementation guarantees low power consumption.
MICROFIP is a low-cost and easy-to-use solution which supplies a subset
of the WorldFIP services, in particular it can be configured as a
station, without being able to run the bus arbitrator. The frame
delimiters and control sequence can be selected in compliance with the
NFC46-604 FIP original standard or IEC11586-2. Network management
facilities are directly embedded in the chip, such as the presence and
identification variables. The identification contains a 32-bit tag.
The MICROFIP chip is packaged in the MQFP100 standard solution, and the
3.3-volt and 5-volt nominal power supply can be selected.
In 2009 Alstom decided to phase-out MicroFIP
