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 company Alstom.
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 support.
