LAN9255-V/ZMX018

Controllers Overview

The LAN9255-V/ZMX018 is a System-In-Package (SIP) combining the Microchip LAN9253 EtherCAT device controller and SAM E53J ARM Cortex-M4F MCU. It features integrated 100Mbps Ethernet PHYs with HP Auto-MDIX, 8 FMMUs, and 8 SyncManagers. The MCU includes 256 KB in-system programmable flash, 128 KB SRAM, dual 1 Msps 12-bit ADCs, USB 2.0, and an Ethernet MAC with 1588 PTP/TSU. Operating at -40°C to +105°C, it uses a single 3.3V supply and comes in a 128-pin TQFP package.

Controllers Feature Summary

• Integrates an ARM Cortex-M4F microcontroller with 256 KB of flash memory and 128 KB of SRAM alongside an EtherCAT device controller.
• Includes dual integrated 100Mbps Ethernet transceivers supporting HP Auto-MDIX and transformer-less link configurations.
• Supports distributed clock synchronization via 8 Fieldbus Memory Management Units (FMMUs) and 8 SyncManagers.
• Features comprehensive power management capabilities including multiple sleep modes and various wake-up sources.

Controllers Applications

• Motor Motion Control
• Process and Factory Automation
• Communication Modules and Interface Cards
• Hydraulic and Pneumatic Valve Systems

Controllers Procurement Notes

Verify the ordering suffix ZMX018 confirms the 256 KB memory configuration and V indicates extended industrial temperature range (-40°C to +105°C). Ensure the package type matches the 128-pin TQFP specification. Confirm that the specific silicon revision aligns with the current datasheet DS00003646B requirements for optimal interfacing between the LAN9253 and SAM E53J dies.

Controllers Selection Notes

Select this variant when 256 KB of program memory is sufficient for the application logic within the Cortex-M4F core. The extended industrial temperature rating makes it suitable for harsh environments where standard commercial or industrial grades are insufficient. Verify that the host interface requirements match the available SPI/QSPI or HBI modes supported by the integrated controller.

Controllers Part Context

This component belongs to the LAN9255 family of EtherCAT controllers. The ZMX018 suffix specifically denotes the 256 KB memory configuration, distinguishing it from the 512 KB (ZMX019) and 1024 KB (ZMX020) variants. All variants share the same pinout and core functionality but differ in available on-chip storage capacity.

Controllers Replacement Considerations

LAN9255-I/ZMX018 offers the same memory size but operates at -40°C to +85°C. LAN9255/ZMX018 provides commercial temperature range (0°C to +70°C). For higher memory needs, consider LAN9255-V/ZMX019 (512 KB) or LAN9255-V/ZMX020 (1024 KB).
