概述

Description

ENC424J600T-I/PT is Microchip’s stand-alone Ethernet controller with an SPI interface. It provides a full MAC and PHY plus a DMA-based packet engine, enabling a microcontroller without an integrated Ethernet MAC to connect to a 10/100 Mbps Ethernet network via SPI.
Key features (high level):
- 10/100 Mbps Ethernet with IEEE 802.3 framing, auto-negotiation, and full/half‑duplex support
- MAC/PHY with DMA for efficient data transfer between SPI host and Ethernet network
- Packet filtering, CRC/checksum offload, and interrupt signaling
- SPI host interface (to a microcontroller) with typical low-pin-count connection
- Power-management options and common I/O options for embedded use
- Industrial temperature variant (-I) and packaging (-PT means Plastic, Tape & Reel)
Typical use:
- Add Ethernet connectivity to MCUs without built‑in MAC/PHY (industrial controllers, gateways, IoT sensors)
Note: Requires appropriate software support (e.g., Microchip libraries) and may need external memory/buffers as per the design.

Features

Here are the key features of ENC424J600T-I/PT (standalone Ethernet controller with SPI interface):
- Standalone Ethernet controller with built-in hardware TCP/IP stack (IP/TCP/UDP/ICMP/ARP) and a DHCP client.
- 10/100 Mbps MAC/PHY with IEEE 802.3, auto-negotiation, supports full- and half-duplex operation.
- SPI host interface to a microcontroller (high-speed SPI, register/memory-mapped access).
- On-chip RAM for packet buffering and TCP/IP state; supports multiple sockets/queues.
- IEEE 802.3 compliant network interface with packet filtering (unicast/multicast/broadcast).
- Interrupts and status registers for event-driven operation; configurable LEDs for link/activity.
- Industrial temperature range (-40 °C to +85 °C); packaging variants -I/PT (RoHS plastic, tape & reel).
- Designed for low-pin-count embedded systems needing a complete Ethernet solution.
Notes: It’s a network controller, not a microcontroller, and is typically used with a host MCU via SPI to handle Ethernet connectivity.

Package

ENC424J600T-I/PT uses a 64‑pin Plastic TQFP (LQFP) package. The -PT suffix indicates Tape & Reel shipping.

Pinout

- Pin count: 100 pins (TQFP package).
- Function: Ethernet controller with MAC/PHY (10/100 Mbps) that is controlled via SPI from a host microcontroller (provides the Ethernet data path to RJ45 through magnetics).

Manufacturer

- Manufacturer: Microchip Technology Inc.
- What kind of company: An American multinational semiconductor company that designs and manufactures microcontrollers, memory, analog/mixed-signal ICs, and connectivity solutions for embedded systems (e.g., PIC microcontrollers, Ethernet/controllers).

Application

ENC424J600T-I/PT is a stand-alone 10/100 Ethernet MAC+PHY with SPI interface to add Ethernet to MCU-based designs. Applications: industrial automation and control (PLCs, remote I/O), data logging/telemetry and remote monitoring, building automation (HVAC, lighting, access control), energy meters and smart sensors, networked consumer devices (printers, gateways), medical instrumentation, and embedded networking gateways/bridges.
