Product Details

The fido5100 and fido5200 (REM switch) are programmable IEEE 802.3 10 Mbps/100 Mbps Ethernet Internet Protocol Version 6 (IPv6) and Internet Protocol Version 4 (IPv4) switches that support virtually any Layer 2 or Layer 3 protocol. The switches are personalized to support the desired protocol by firmware that is downloaded from a host processor.

The firmware is contained in the real-time Ethernet multiprotocol (REM) switch driver and is downloaded at power-up. The REM switch can be ready for network data operation in less than 4 ms to support fast startup and quick connect type network functionality. The REM switch devices have the same signal assignments as defined in this data sheet.

The fido5100 supports the following protocols: PROFINET real time (RT) and isochronous real time (IRT), EtherNet/IP with and without device level ring (DLR), Modbus TCP, and POWERLINK.

The fido5200 supports the following protocols: EtherCAT and all protocols defined for the fido5100.

The REM switch is intended for use with a host processor. Network operation is handled using the functions and services provided in the REM switch driver. The host processor can implement any protocol stack by integrating it with the REM switch driver. An example application is shown in Figure 11.

The REM switches are available in a 144-ball chip scale package ball grid array (CSP_BGA) package.

Note that throughout this data sheet, multifunction pins, such as A02/ALE, are referred to either by the entire pin name or by a single function of the pin, for example, ALE, when only that function is relevant.
