Microchip Ethernet MCU/MPU Product Line Overview

Microcontrollers (MCUs) and microprocessors (MPUs) serve as the core of embedded systems, and their network connectivity capabilities directly impact the intelligence level of devices. Microchip's Ethernet MCU/MPU product line covers a wide range of application scenarios from basic 10/100Mbps to gigabit Ethernet, combining high performance with low power consumption, offering developers flexible and diverse options.

High-Performance Ethernet Microcontroller Series

Microchip's Ethernet MCU series integrates Ethernet MAC controllers and rich peripheral interfaces, significantly simplifying the development of embedded network devices. These devices are typically based on ARM Cortex-M or Microchip's proprietary PIC architecture, offering processing performance ranging from 48MHz to 300MHz to meet the computational requirements of different application scenarios.

Key features include:

Integrated MAC+PHY design: Some models, such as the LAN8740/LAN8742, integrate a 10/100Mbps Ethernet PHY, requiring only an external network transformer to achieve full Ethernet functionality, significantly reducing PCB area and BOM costs.

Industrial-grade reliability: Operating temperature range from -40°C to +105°C, with strong anti-interference capabilities, suitable for harsh environments such as industrial automation and power communication.

Low-power optimisation: Dynamic power consumption as low as 100μA/MHz, with power consumption of only 3μA in deep sleep mode, supporting fast wake-up (deep sleep wake-up time <18μS), ideal for battery-powered IoT devices.

Rich peripheral interfaces: Integrated high-speed SPI, I2C, UART, CAN-FD communication interfaces, and built-in high-speed ADC/DAC modules to meet real-time data acquisition and multi-sensor connection requirements.

Security features: Some high-end models support secure boot and encryption engines (such as AES-256), enhancing system security and preventing firmware tampering and data leakage.

Gigabit Ethernet microprocessor solutions

Microchip's Gigabit Ethernet MPU processors are based on high-performance ARM Cortex-A cores, with clock speeds exceeding 500MHz, and support complex operating systems such as Linux, making them suitable for gateways, edge computing, and other scenarios.

Typical application scenarios:

Industrial IoT gateways: Aggregate data from multiple devices via Gigabit Ethernet and connect to the cloud via Wi-Fi/4G modules.

Smart home hubs: Process network requests from multiple smart devices and run complex home automation logic.

Industrial control host: Runs real-time control systems and communicates with multiple PLC and HMI devices via Ethernet.

Medical monitoring equipment: Transmits medical imaging data at high speeds while ensuring network connection reliability and low latency.

Ethernet AVB/TSN terminal device solutions

With the development of industrial internet and autonomous driving technology, traditional Ethernet faces challenges in terms of real-time performance and determinism. Audio Video Bridging (AVB) and Time-Sensitive Networking (TSN), as IEEE-standardised real-time Ethernet extensions, provide deterministic low-latency communication guarantees for audio-video transmission and industrial control. Microchip Ethernet AVB/TSN terminal devices integrate the necessary protocol stacks, significantly simplifying the development process and accelerating time-to-market.

AVB/TSN Technology Overview

AVB/TSN is a set of IEEE 802.1 standards designed to enhance the real-time performance of standard Ethernet. Its key technical features include:

Time Synchronisation: Achieves nanosecond-level clock synchronisation via the IEEE 802.1AS-Rev protocol, providing a unified time reference for distributed systems.

Traffic Scheduling: The IEEE 802.1Qbv Time-Aware Shaper (TAS) ensures that critical traffic is transmitted within a predefined time window, avoiding conflicts.

Frame Preemption: IEEE 802.1Qbu allows high-priority frames to interrupt the transmission of low-priority frames, reducing latency for critical traffic.

Seamless Redundancy: IEEE 802.1CB frame replication and elimination mechanisms enhance network reliability.

These technologies enable standard Ethernet to meet the stringent requirements for deterministic latency and reliability in applications such as industrial automation, in-vehicle networks, and professional audio/video.

Microchip AVB/TSN Terminal Product Features

High Protocol Integration: Built-in complete AVB/TSN protocol stack, including IEEE 802.1AS time synchronisation and IEEE 1722 audio/video transmission protocol, eliminating the need for developers to build software protocol stacks from scratch, saving months of development time.

High hardware timestamp accuracy: Integrated IEEE 1588v2 hardware timestamp functionality with synchronisation accuracy of ±15ns, meeting the most stringent industrial synchronisation requirements.

Audio/video clock generation: Generates media clocks (wall clock synchronisation) and supports FSYNC/SCLK generation via I2S/TDM8 interfaces, directly driving audio codecs.

Low-power design: Supports TC10 low-power sleep mode with sleep current below 20 µA, and features both local and remote wake-up functionality, making it suitable for battery-powered devices.

Rich diagnostic features: Built-in temperature, voltage, and ESD monitors, data throughput calculator, signal quality indicator, and TDR-based cable fault detection functionality simplify system debugging and maintenance.

Typical application scenarios

Industrial automation:

Motion control systems: Achieve precise synchronisation of multi-axis servo drives with synchronisation accuracy down to the microsecond level.

Distributed I/O systems: Achieve deterministic response of remote I/O modules via TSN networks, replacing traditional fieldbuses.

Automotive Electronics:

Advanced Driver Assistance Systems (ADAS): Real-time transmission and synchronised processing of sensor data from cameras, radars, and other sensors.

Professional Audio/Video:

Live Audio/Video Production: Lossless transmission of multi-channel audio and 4K video streams with ultra-low latency.

Digital Signage Systems: Synchronised control of content playback across multiple display terminals.

IoT Edge Computing:

Industrial IoT Gateways: Aggregate data from various field devices and ensure real-time transmission of critical data via TSN.
