ADIN1110CCPZ-R7

Overview

The ADIN1110CCPZ-R7 is a low-power, single-port 10BASE-T1L Ethernet MAC-PHY compliant with IEEE 802.3cg-2019. It integrates an Ethernet PHY core, MAC, and analog circuitry, communicating via a 4-wire SPI interface. Operating from a single supply of 1.8 V or 3.3 V (AVDD_H/L: 1.71 V to 3.46 V; VDDIO: 1.71 V to 3.46 V), it supports data rates of 10 Mb/s. The device features programmable transmit levels of 1.0 V p-p and 2.4 V p-p, enabling cable reaches up to 1700 m. It includes on-chip FIFOs (20 kB RX, 8 kB TX), IEEE 1588 timestamp support, and operates within an extended temperature range of −40°C to +105°C.

Feature Summary

• Integrated MAC with SPI interface for direct connection to host processors without integrated MAC
• Supports intrinsic safety applications via programmable transmit levels and external termination resistors
• Advanced diagnostics including Time Domain Reflectometry (TDR) for cable fault detection
• High and low priority queues with 28 kB buffer supporting cut-through or store-and-forward operation

Applications

• Field instruments in process automation
• Building automation and fire safety systems
• Factory automation and edge sensors
• Condition monitoring and machine connectivity

Procurement Notes

Verify the specific suffix -R7 indicates reel packaging when sourcing. Confirm that the component meets RoHS compliance requirements for your region. Ensure the host system voltage rails align with the specified AVDD and VDDIO ranges. Check for moisture sensitivity level handling requirements during assembly. Validate that the LFCSP-40 package footprint matches your PCB design guidelines.

Selection Notes

Select this component when a low-power solution is required for 10BASE-T1L networks without a host processor containing an integrated MAC. It is suitable for applications needing long cable reach up to 1700 meters. Consider this part for environments requiring robust EMC performance and intrinsic safety certification support. It simplifies design by integrating MAC functions accessible via SPI.

Part Context

The ADIN1110 belongs to Analog Devices' portfolio of industrial Ethernet solutions designed for Single Pair Ethernet (SPE). It complements other devices like the ADIN1100 PHY and ADIN2111 switch by providing a complete MAC-PHY solution. This integration reduces system complexity and power consumption compared to using separate MAC and PHY components in industrial IoT deployments.

Replacement Considerations

Public confirmed substitutes include the ADIN1110CCPZ tray version, which shares identical electrical specifications but differs in packaging format. No other functional equivalents are publicly documented as direct replacements with identical pinouts and feature sets.
