ADIN1110BCPZ

Overview

The ADIN1110BCPZ is a low-power, single-port 10BASE-T1L Ethernet MAC-PHY designed for industrial applications. It integrates an Ethernet PHY core with a MAC and associated analog circuitry, communicating via a 4-wire SPI interface. The device supports cable reaches up to 1700 meters with 1.0 V or 2.4 V transmit levels. Power consumption is typically 42 mW in dual-supply mode at 1.0 V p-p. It operates from a single 1.8 V or 3.3 V supply rail and features integrated voltage monitoring and power-on reset.

Feature Summary

• Integrated MAC with SPI interface for direct host connection
• Supports intrinsic safety applications via programmable transmit levels and external termination
• On-chip diagnostics including TDR cable fault detection and link quality monitoring
• IEEE 1588 timestamp support for precise time synchronization

Applications

• Field instruments
• Building automation and fire safety
• Factory automation
• Edge sensors and actuators
• Condition monitoring and machine connectivity

Procurement Notes

Verify the specific package variant (CP-40-292) and temperature grade when sourcing. Confirm that the ordering suffix corresponds to the desired operational range, as standard industrial grades cover -40°C to +85°C while extended grades reach +105°C. Ensure compatibility with the required SPI protocol configuration, either Open Alliance or generic, based on system design constraints.

Selection Notes

Select this component for systems requiring ultra-low power consumption without an integrated MAC processor. The ADIN1110 allows lower-power hosts to connect directly via SPI. Consider the available transmit amplitude options; 1.0 V p-p offers lower power, while 2.4 V p-p extends reach. Ensure the host controller supports the necessary SPI timing requirements for full 10 Mbps bandwidth.

Part Context

The ADIN1110 belongs to Analog Devices' Chronous industrial Ethernet portfolio, focusing on long-reach Single Pair Ethernet (SPE). It complements other devices like the ADIN1100 PHY by providing integrated MAC functionality. This integration simplifies designs for edge nodes, reducing component count and overall system power compared to solutions using separate MAC and PHY components.

Replacement Considerations

The ADIN1100 serves as a functional alternative if the host system already includes a MAC controller, as it provides only the PHY layer. Both devices share similar packaging and pinout characteristics for MDI interfaces. Designers should verify SPI versus standard Ethernet MAC interface requirements when substituting between these parts.
