ENC28J60T/ML

Controllers Overview

The ENC28J60T/ML is a standalone Ethernet controller manufactured by Microchip Technology, designed for IEEE 802.3 compatibility. It integrates a MAC and a 10Base-T PHY within a single package, supporting both full-duplex and half-duplex communication modes. The device features an SPI interface with clock speeds up to 20 MHz for host communication. Internal resources include an 8-Kbyte dual-port SRAM buffer for packet storage and hardware-managed circular receive FIFO. Key electrical specifications include an operating voltage range of 3.1V to 3.6V (typical 3.3V) and an industrial temperature rating from -40°C to +85°C. The component utilizes a 25 MHz crystal oscillator input.

Controllers Feature Summary

• Integrated MAC and 10Base-T PHY with automatic polarity detection and correction capabilities.
• Hardware-assisted checksum calculation and internal DMA for efficient data throughput.
• Configurable packet filtering including unicast, multicast, broadcast, and pattern matching support.
• Programmable LED outputs for link status and network activity indication.

Controllers Applications

• Embedded systems requiring low-cost wired network connectivity.
• Industrial automation controllers and sensors.
• Smart home devices and remote monitoring equipment.
• Consumer electronics with Ethernet interface requirements.

Controllers Procurement Notes

Verify the specific suffix 'ML' against official datasheets to confirm package type and temperature grade. Ensure ordering documentation matches the required RoHS compliance status. Confirm availability through authorized distributors as supply levels fluctuate. Check for any recent product change notifications regarding packaging or assembly modifications.

Controllers Selection Notes

Select this component when a cost-effective solution for 10Mbps Ethernet is required without external PHY chips. Suitable for microcontrollers lacking native MAC interfaces but possessing SPI capability. Consider the 8KB RAM limitation for high-throughput applications. Verify that the host system can provide the necessary 25MHz clock source via crystal or external oscillator.

Controllers Part Context

This part belongs to the ENC28J60 family of standalone Ethernet controllers. It shares core functionality with variants like the ENC28J60-I/SO and ENC28J60T-I/SS, differing primarily in package style and reel configuration. The ML suffix typically denotes a specific surface-mount package variant offered by Microchip for automated assembly processes.

Controllers Replacement Considerations

Direct replacements include other packages within the same ENC28J60 family such as SOIC or SSOP versions. For pin-compatible alternatives with integrated protocol stacks, consider W5500 or W6100 series controllers, though these offer different architectural approaches and higher performance.
