FIDO5210BBCZ-R7

Controllers Overview

The FIDO5210BBCZ-R7 is a Real-Time Ethernet Multiprotocol (REM) switch manufactured by Analog Devices Inc. It features two independent Ethernet ports supporting 10 Mbps and 100 Mbps speeds with half and full duplex capabilities. The device operates on a core voltage of 1.08 V to 1.32 V and an I/O voltage of 2.97 V to 3.63 V, consuming a maximum core current of 48 mA at 85°C. It supports IEEE 1588 Version 2 for precise time synchronization and includes an internal precision timer with 1 ns resolution. The component is housed in a 144-lead CSP_BGA package and is rated for industrial temperatures from -40°C to +105°C.

Controllers Feature Summary

• Supports multiple industrial protocols including PROFINET Class B/C, EtherNet/IP, Modbus TCP, and EtherCAT.
• Integrates PriorityChannel technology for efficient data transfer and immunity to network loading effects.
• Provides hardware timestamping via IEEE 1588 Version 2 support for ordinary and transparent clock modes.
• Includes an internal precision timer capable of generating programmable periodic waveforms synchronized to system time.

Controllers Applications

• Industrial automation
• Process control
• Instrumentation

Controllers Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing components. Confirm that the BBCZ designation corresponds to the standard RoHS-compliant CSP_BGA package variant. Ensure compatibility with the required host interface configuration before procurement.

Controllers Selection Notes

Select this model for applications requiring multiprotocol Real-Time Ethernet support without external PHY dependencies for basic switching logic. Consider the 144-lead CSP_BGA package constraints during PCB layout. Verify that the host processor can accommodate the 32-bit parallel interface timing requirements specified in the datasheet.

Controllers Part Context

This component belongs to the fido5100/fido5200 family of Real-Time Ethernet switches. While the fido5100 focuses on PROFINET and EtherNet/IP, the fido5200 series adds native support for EtherCAT. Both share the same REM architecture and physical interface specifications.

Controllers Replacement Considerations

The fido5100BBCZ serves as a functional alternative if EtherCAT support is not required. Verify pinout and software driver compatibility when substituting between fido5100 and fido5200 variants within the same package.

Controllers FAQ

Does the FIDO5210BBCZ-R7 integrate physical layer transceivers?

No, the device provides MII and RMII digital interfaces. External PHYs are required to connect to the physical Ethernet cables.

What is the resolution of the internal precision timer?

The internal precision timer maintains system time with a resolution of 1 nanosecond.

Can the device operate in both big-endian and little-endian modes?

Yes, the endianness is configurable via the LE pin. Setting the pin high enables little-endian format, while low enables big-endian format.
