LAN9255/ZMX020

Controllers Overview

The LAN9255/ZMX020 is a System-In-Package (SIP) combining the Microchip LAN9253 EtherCAT device controller and SAM E53J ARM Cortex-M4F MCU in a 128-pin TQFP package. It features integrated 100Mbps Ethernet PHYs with HP Auto-MDIX, 8 FMMUs, and 8 SyncManagers. The MCU includes 1024 KB flash, 256 KB SRAM, dual 1 MSPS 12-bit ADCs, and USB 2.0 interfaces. Operating at a single 3.3V supply, it supports extended industrial temperatures (-40°C to +105°C).

Controllers Feature Summary

• Integrates an ARM Cortex-M4F MCU with extensive memory and peripherals alongside an EtherCAT device controller.
• Includes dual integrated 100Mbps Ethernet transceivers with automatic polarity detection and cable diagnostics.
• Supports distributed clock synchronization and comprehensive power management including multiple sleep modes.

Controllers Applications

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

Controllers Procurement Notes

Verify the specific ordering suffix to confirm the temperature range and memory configuration. The ZMX020 suffix indicates the 128-pin TQFP package with 1024 KB of programmable memory. Ensure the selected variant matches the required thermal operating conditions for the target application environment.

Controllers Selection Notes

Select this component when a combined EtherCAT communication interface and processing unit is required. The integrated design reduces board space compared to discrete solutions. Verify that the host system can utilize the available SPI or HBI interfaces for optimal data throughput and control.

Controllers Part Context

This part belongs to the LAN9255 family of EtherCAT controllers. Variants differ by temperature rating and internal memory size. The ZMX020 designation specifically identifies the extended industrial temperature version with the maximum 1024 KB memory capacity within the standard TQFP packaging.

Controllers Replacement Considerations

Discrete alternatives require separate components for the MCU and EtherCAT controller. Direct pin-compatible replacements are not publicly documented for this specific SIP configuration. Evaluate the LAN9253 controller paired with a standalone SAM E53J MCU if modular design is preferred.
