REM switches support virtually any Layer 2 or Layer 3 protocol
Connectors, Switches & EMECH
Analog Devices fido5100/fido5200 Real-Time Ethernet Multiprotocol (REM) Switches are produced as programmable IEEE 802.3 10Mbps/100Mbps Ethernet Internet Protocol Version 6 (IPv6) and Internet Protocol Version 4 (IPv4) switches supporting practically any Layer 2 or Layer 3 protocol.
The switches are created to support the protocol used by the firmware downloaded from a host processor. These two-port, embedded Ethernet switches can interface to any processor, which includes any ARM CPU and the fido1100 Communication Controller. The host processor can execute any protocol stack by combining it with the REM switch driver. To support fast startup and quick-connect type network process, the firmware is downloaded in power-up mode and held in the REM switch driver. The REM Switches can be ready for network data operation in only 4ms. These switches also include a powerful memory bus interface that supports both 16 and 32-bit wide busses and delivers data transfer rates up to 167Mbytes/sec.
