ADIN1111BCPZ-R7

Overview

The ADIN1111BCPZ-R7 is a low-power Ethernet MAC-PHY integrated circuit designed for Single Pair Ethernet (SPE) applications. It complies with the IEEE 802.3cg-2019 standard for 10BASE-T1L, supporting data rates of 10 Mb/s over distances up to 1.7 km. The device integrates an Ethernet PHY core, MAC, and associated analog circuits within an LFCSP-32 package. It operates on a supply voltage ranging from 1.71 V to 3.46 V and supports both half-duplex and full-duplex communication modes.

Feature Summary

• Integrates 10BASE-T1L MAC and PHY functions for simplified system design
• Supports Single Pair Ethernet (SPE) connectivity for industrial sensor networks
• Features SPI interface for host configuration and management

Applications

• Industrial automation and process control systems
• Smart building infrastructure and lighting controls
• Automotive sensor networks and body electronics
• Energy metering and utility infrastructure

Procurement Notes

Verify the specific suffix 'R7' against official Analog Devices documentation to confirm reel packaging specifications. Ensure compatibility with the intended PCB footprint, specifically the LFCSP-32 package dimensions. Confirm moisture sensitivity level handling requirements during assembly, as indicated in the datasheet. Cross-reference the part number with current manufacturer availability status to avoid obsolescence risks.

Selection Notes

Select this component when a combined MAC-PHY solution is required for 10BASE-T1L networks. It is suitable for designs needing reduced bill-of-materials count compared to discrete PHY and MAC controllers. Consider the power consumption profile for battery-operated or energy-harvesting applications. Verify that the host processor can support the necessary SPI interface speed and register map access.

Part Context

The ADIN1111 belongs to Analog Devices' portfolio of Single Pair Ethernet solutions, complementing devices like the ADIN1100 PHY and ADIN2111 switch. This series targets the growing market for IoT endpoints and industrial fieldbus replacements. The BC variant typically denotes specific temperature or package grading within the broader ADIN1111 family line.

Replacement Considerations

Direct pin-to-pin replacements are limited within the same family. The ADIN1110 serves as a related MAC-PHY alternative but may lack the dual MDI capability found in some CC variants. Verify software driver compatibility if migrating between closely related models.
