ADIN2111BCPZ-R7

Overview

The ADIN2111BCPZ-R7 is a low-complexity, dual-port Ethernet switch IC integrating two 10BASE-T1L PHYs compliant with IEEE 802.3cg-2019. It supports cable reach up to 1700 meters and operates at 10 Mbps full duplex. Power consumption is 77 mW (dual supply, 1.0 V p-p) or 90 mW (single supply). The device features an integrated switch supporting cut-through or store-and-forward modes, 28 kB buffer memory, and 16 MAC address filters. It interfaces via SPI, supports OPEN Alliance or generic protocols, and includes diagnostics like TDR. Operating voltage ranges from 1.8 V to 3.3 V, with industrial (-40°C to +85°C) and extended (-40°C to +105°C) temperature options.

Feature Summary

• Integrates a 2-port switch with 10BASE-T1L PHYs for line, daisy-chain, or ring topologies
• Supports OPEN Alliance SPI and generic SPI with optional CRC data protection
• Includes comprehensive on-chip diagnostics such as Time Domain Reflectometry (TDR)
• Features integrated power monitoring and reset circuits for system robustness

Applications

• Building automation and fire safety systems
• Factory automation networks
• Condition monitoring and machine connectivity

Procurement Notes

Verify the specific suffix against the manufacturer's current ordering guide to confirm package type and temperature range. Ensure compatibility with host controller SPI timing requirements. Confirm EMC compliance needs against IEC standards relevant to the deployment environment.

Selection Notes

Select based on required network topology support and power budget constraints. Evaluate whether single or dual supply configurations fit the system design. Consider the need for managed versus unmanaged switching capabilities when designing the host interface logic.

Part Context

This component belongs to Analog Devices' portfolio of industrial Ethernet solutions designed for Single Pair Ethernet (SPE) applications. It complements other PHY and switch devices by offering a compact, low-power solution for edge nodes in constrained environments.

Replacement Considerations

Consult official documentation for qualified substitute part numbers within the same product family or series before implementation.
