The fido5100 and fido5200 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 fido5100/fido5200 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, SERCOS III, 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 fido5100 and fido5200 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.

Evaluation Kits (1)
The RapID Platform Network Interface solutions are pre-tested Industrial Network interfaces that manage the industrial protocol and network traffic. Thanks to the module’s Unified Interface, a single host interface hardware and software design supports PROFINET, PROFINET IRT, PROFIBUS, EtherNet/IP, EtherNet/IP with DLR, EtherCAT, and ModbusTCP. Choose the type of Network Interface to support the required Industrial protocols. The Unified Interface also ensures your host processor hardware or software interface does not need to change even when you switch or update protocols. The Network Interface connects to a host processor via a UART, 16-bit Parallel Interface, or Ethernet (future).
The evaluation kit provides a quick assessment for interfacing a host processor to the Network Interface module (module is sold separately). Once host-side communication is established, communication can be evaluated using third-party PC-based tools or vendor-specific Programmable Logic Controllers (PLC). The communication path between the host processor and a PLC can be completely verified before integrating the Network Interface into your end field device. Please take a moment to verify the contents of your evaluation kit.
