ADIN1110BCPZ-R7

Overview

The ADIN1110BCPZ-R7 is a low-power, single-port 10BASE-T1L Ethernet MAC-PHY transceiver compliant with IEEE 802.3cg-2019. It integrates an Ethernet PHY core with a MAC and analog circuitry, operating from a single 1.8 V or 3.3 V supply rail. The device features a 4-wire SPI interface for host communication, supporting up to 10 Mbps full-duplex data rates. Power consumption is typically 42 mW in dual-supply mode with 1.0 V p-p transmit levels. It supports cable reaches exceeding 1700 meters and includes integrated voltage monitoring and power-on reset circuitry.

Feature Summary

• Integrated MAC with SPI interface supporting Open Alliance and generic protocols
• Programmable transmit levels (1.0 V p-p and 2.4 V p-p) suitable for intrinsic safety applications
• On-chip diagnostics including Time Domain Reflectometry (TDR) and link quality monitoring
• IEEE 1588 timestamp support with high and low priority receive queues

Applications

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

Procurement Notes

Verify the specific suffix BC indicates the extended temperature range (-40°C to +105°C) as defined in the manufacturer's ordering guide. Confirm package type is the 40-lead LFCSP. Check for RoHS compliance status in the latest datasheet revision. Ensure the source document explicitly lists this part number variant to avoid confusion with industrial grade versions.

Selection Notes

Select this component for systems requiring ultra-low power consumption in industrial Ethernet environments. It is ideal for host controllers lacking an integrated MAC, as the SPI interface reduces overall system power. Consider the external termination resistor requirement and independent Rx/Tx pins when designing for intrinsic safety zones. Verify that the host processor supports the required SPI timing characteristics for reliable communication.

Part Context

This part belongs to the ADIN1110 family of 10BASE-T1L MAC-PHY devices designed for long-reach, single-pair Ethernet applications. The series targets industrial automation and IoT edge nodes where power efficiency and robustness are critical. The BC suffix typically denotes the extended temperature range variant within the product line, distinguishing it from standard industrial temperature options.

Replacement Considerations

Publicly confirmed substitutes include other 10BASE-T1L MAC-PHY devices from Analog Devices such as the ADIN1100, though pinouts and feature sets may differ. Evaluate alternative vendors only if they offer IEEE 802.3cg compliance and similar SPI interfaces. Verify thermal performance and supply voltage compatibility before substitution.

FAQ

What is the maximum cable reach supported by the ADIN1110?

The device supports a cable reach of over 1700 meters when configured with 1.0 V p-p or 2.4 V p-p transmit levels.

How does the ADIN1110 handle intrinsic safety applications?

It is suited for intrinsic safety due to programmable transmit levels, external termination resistors, and independent Rx/Tx pins which allow for safe energy limiting in hazardous areas.

Does the ADIN1110 support hardware-based configuration?

Yes, it supports unmanaged configuration using hardware pin strapping for settings such as master/slave selection, transmit amplitude, and clock input type.
