上周，在加州圣克拉拉举行的 Technology Days 活动上，NXP Semiconductors 推出了一系列新的 MCU，旨在将工厂自动化或边缘 IoT 环境中原本不可见的端点转变为基于 IP 的节点，这些节点的数据可以有效地为运营智能和自动化做出贡献。

其新的 MCX A5 系列 MCU 据称可简化工业和 IoT 边缘应用的安全连接，该公司声称这是业界首次在带有 10BASE-T1S 以太网数字 PHY 的有线 MCU 上实现拓扑发现，并由后量子密码学 (PQC) 保护。

在我们看来，拓扑发现在这里意义重大。过去，在多分支工业网络上添加多个端点时没有 IP 节点映射，而此功能可以使所有这些节点可见。NXP 安全连接边缘产品高级总监 Justin Mortimer 在活动上表示：“MCX A5 使 IP 网络真正普及到传感器、执行器、小型 HMI 和电机控制器，同时保留了现场总线的安装简便性。”

公司的官方公告称，集成的 10BASE-T1S 以太网使制造商能够将基于 IP 的连接更深地扩展到工业系统中，连接更多传感器、执行器和控制器，同时降低系统成本和复杂性。拓扑发现自动识别和映射连接的设备，提高网络可见性并简化部署。NXP 表示，这使 MCX A5 系列能够将更多设备转变为可访问的实时数据源，用于分析、自动化和其他工业边缘 AI 应用。

“我们通过 MCX A5 所做的是将 10BASE-T1S 以太网一直带到端点，关键是你可以看到网络上的所有节点，”Mortimer 说。

他进一步解释说：“今天，当你有一个像 RS 485 这样的现场总线时，它变得有点模糊：你有一个控制器或 PLC，然后所有这些节点串在多分支总线上。但你在所有这些端点上没有以太网 IP 地址，你也不一定能获得对整个网络的同等可见性。借助 MCX A5，我们能够通过新技术自动发现和映射工业网络，你可以在微控制器中进行拓扑发现。”

对于操作员和维护团队来说，这意味着以前不透明的网络突然变得可视化：HMI 可以显示整个总线布局并突出显示特定设备。

Mortimer 补充说，新的微控制器系列是缺失的一环，它将 IP 网络和强大的安全性一直带到最小的工业终端节点。这种可见性在以下情况下很有价值：例如，在棕色地带总线上更换单个传感器或执行器而不影响其他部分；或诊断故障，如电缆挤压或不可靠的节点；以及随着时间的推移从传统现场总线逐步升级到基于 IP 的网络。

他还强调，拓扑发现并非持续运行，它是一种配置、诊断和维护工具，而不是持续的背景进程。

在整个生命周期内维护设备安全

很明显，一旦你开始在多分支电缆上为更多节点分配 IP 地址，那么每个节点也会增加网络的潜在攻击面。因此，新的 MCX A5 系列不仅包含 PSA Certified Level 3 安全认证，还支持 PQC，包括基于 PQC 的硬件信任根，涵盖安全启动、安全固件更新、安全认证和安全调试认证。部分器件还支持 Rust 编程语言，使开发人员能够采用现代、内存安全的软件开发实践。

Mortimer 反复强调安全是设计的核心，而不是事后考虑。“这不仅是因为今天需要，而是关于未来 10-20 年保护我们的东西，”他说。

对于 OEM 来说，这很重要，因为工业节点通常必须在现场使用超过十年，而像 CRA（网络弹性法案）这样的法规开始要求长期可更新性和安全维护。

当与 NXP 的 TJF1410 10BASE-T1S 物理介质相关 (PMD) 收发器配合使用时，MCX A5 系列为工业和楼宇自动化应用提供了完整的单对以太网 (SPE) 解决方案，TJF1410 充当 MCX A5 集成数字 PHY 的模拟前端。TJF1410 针对符合 IEEE 802.3cg 的 10BASE-T1S 网络进行了优化，并补充了 MCX A5 的集成数字 PHY，NXP 表示这简化了系统设计并降低了工业自动化、楼宇自动化、能源基础设施和其他分布式边缘应用的物料清单成本。

推动工业和商业领域的实际采用

虽然 MCX A5 是一个通用工业 MCU 系列，但 Mortimer 强调了几个早期重点领域。这些包括物流和仓储、楼宇自动化以及机器人和物理 AI。

例如，他说其一个物流合作伙伴定期分阶段扩展其仓库输送机和分拣系统。随着每个新输送机段的添加，借助新的 MCU 和 10BASE-T1S，该合作伙伴可以沿每个输送机段添加基于 IP 的节点，并进行增量扩展和更换，而无需重新布线整个系统。

据 Mortimer 称，楼宇自动化是一个特别强大的早期采用者垂直领域。许多现有系统仍然使用 RS-485 现场总线用于 HVAC 风门、传感器、执行器和小型 HMI。新 MCU 中的拓扑发现功能提供了一种安装人员熟悉的插入式布线模型（单对、多分支），以及一条通往 IP 可寻址端点的路径，而无需转向笨重的 10/100 以太网硬件。

Mortimer 表示，公司正在积极向该领域的大型 OEM 和较小的子系统供应商提供样品并进行设计讨论。

机器人和物理 AI

机器人和物理 AI 主题是上周 NXP Tech Days 讨论中较大的一部分，演讲者扩展了 NXP 首席执行官 Rafael Sotomayor 今年早些时候在台湾 Computex 上讲述的故事，关于部署“适当大小的智能”以实现可扩展的物理 AI。

在此视频对话中，分析公司 Omdia 的工业半导体首席分析师 Saloni Gankar 就 NXP Tech Days 上的一些关键讨论和公告提供了她的观点，并讨论了工业半导体和物理 AI 市场的更广泛趋势。

这些系统的一个组成部分是分布式微控制器，控制着电机、关节、夹持器和触觉传感器等一切。虽然目前这些 MCU 通常通过短距离总线连接，无法提供良好的全局可见性，但 Mortimer 表示，其新的微控制器可以成为这些分布式控制器的标准构建块，因为机器人的每个肢体或部分——手臂、手、手指——都可以用 10Base-T1S 单对以太网布线。因此，每个执行器和传感器节点都将获得 IP 地址和安全身份。这样，顶级 AI 控制器可以看到并管理整个拓扑，而不是将下游 MCU 视为不透明的孤岛。

他表示，至少有一个机器人客户已经在积极使用相关技术进行设计，并认真考虑将 10BASE-T1S 用于终端节点连接。

MCX A5 系列基于 Arm Cortex-M33 内核，运行频率高达 240 MHz。它提供高达 2 MB 的 Flash、640 KB 的 RAM，以及包括 UART、I²C、I3C、SPI、CAN FD、高速 USB 和 FlexIO 在内的连接接口。除了 NXP 的 FRDM 开发板的支持外，MCX A5 系列还得到 MCUXpresso 开发者生态系统的支持，包括 Rust 支持、全面的 SDK、Visual Studio Code 集成和 LTS 软件版本。MCX A5 系列现已提供样品。

NXP 半导体

At its Technology Days event in Santa Clara, California, last week, NXP Semiconductors introduced a new family of MCUs designed to transform previously invisible endpoints in a factory automation or edge IoT setting into IP-based nodes from which data can usefully contribute to operational intelligence and automation.

Its new MCX A5 family of MCUs are said to simplify secure connectivity for industrial and IoT edge applications, delivering what the company claims is the industry’s first implementation of topology discovery enabled on a wired MCU with 10BASE-T1S Ethernet digital PHY, secured by post-quantum cryptography (PQC).

The topology discovery, in our view, is significant here. Where in the past multiple endpoints were added on a multi-drop industrial network without having IP-node mapping, this feature can make all those nodes visible. Speaking at the event, NXP’s senior director for secure connected edge products, Justin Mortimer, said, “The MCX A5 makes IP networking practical right down to sensors, actuators, small HMIs and motor controllers, while preserving the installation simplicity of fieldbus.”

Justin Mortimer of NXP Semiconductors explains the significance of the company’s new microcontrollers to Nitin Dahad of EE Times in this video interview.

The company’s official announcement stated that integrated 10BASE-T1S Ethernet enables manufacturers to extend IP-based connectivity deeper into industrial systems, connecting more sensors, actuators, and controllers, all while reducing system cost and complexity. Topology discovery automatically identifies and maps connected devices, improving network visibility and simplifying deployment. This, NXP said, enables the MCX A5 family to turn more devices into accessible sources of real-time data for analytics, automation, and other industrial edge AI applications.

“What we do with MCX A5 is we’re bringing 10BASE-T1S Ethernet all the way to the endpoint, and the key is that you can see all the nodes on the network,” Mortimer said.

Explaining further, he said, “Today, when you have a field bus like RS 485, for example, it kind of becomes a little bit gray: you have a controller or a PLC, and then you have all these nodes strung out on a multi-drop bus. But you don’t have an Ethernet IP address at all those endpoints, and you don’t necessarily get the same level of visibility to the whole network. With the MCX A5, we have the ability to automatically discover and map industrial networks with the new technology where you can do topology discovery in the microcontroller.”

For operators and maintenance teams, this means that a network that was previously opaque suddenly becomes visualizable: an HMI can display the entire bus layout and highlight specific devices.

Mortimer added that the new microcontroller family is the missing piece that brings IP networking and strong security all the way down to the smallest industrial end nodes. That visibility pays off when, for example, you are swapping a single sensor or actuator on a brownfield bus without touching the rest; or diagnosing faults such as pinched cables or unreliable nodes; and incrementally upgrading from legacy fieldbus to an IP‑based network over time.

He also stressed that topology discovery isn’t meant to run continuously, it’s a configuration, diagnostics, and maintenance tool, not a constant background process.

Maintaining device security across the entire lifecycle

It’s obvious that once you start giving IP addresses to more nodes on a multi‑drop cable, then each of those nodes also add to the network’s potential attack surface. Hence the new MCX A5 family not only includes PSA Certified Level 3 security, but they also have support for PQC, including a PQC-based hardware root of trust including secure boot, secure firmware updates, secure attestation, and secure debug authentication. Selected devices also support the Rust programming language, enabling developers to adopt modern, memory-safe software development practices.

Mortimer repeatedly framed security as being at the core of the design, and not an afterthought. “It’s not just because that’s what’s needed today, but it’s about what’s going to protect us going into the future for the next 10–20 years,” he said.

For OEMs, this matters because industrial nodes often must stay in the field well beyond a decade, and regulations like the CRA (Cyber Resilience Act) are beginning to require long‑term updatability and security maintenance.

When paired with NXP’s TJF1410 10BASE-T1S physical medium dependent (PMD) transceiver, the MCX A5 family provides a complete single pair Ethernet (SPE) solution for industrial and building automation applications, with the TJF1410 acting as the analog front-end to the MCX A5’s integrated digital PHY. The TJF1410 is optimized for IEEE 802.3cg-compliant 10BASE-T1S networks and complements the MCX A5’s integrated digital PHY, which NXP said simplifies the system design and reduces the bill-of-material costs for industrial automation, building automation, energy infrastructure, and other distributed edge applications.

Driving real-world adoption in industrial and commercial spaces

While MCX A5 is a general‑purpose industrial MCU family, Mortimer highlighted several early focus areas. These include logistics and warehousing, building automation, and robotics and physical AI.

For example, he said one of its logistics partners regularly expands its warehouse conveyors and sorting systems in stages. As each new conveyor segment is added, with the new MCU and 10BASE-T1S, that partner can add IP‑based nodes along each conveyor section, and conduct incremental expansion and replacement without having to re‑wire the entire system.

Building automationis a particularly strong early adopter vertical, according to Mortimer. Many existing systems still use RS‑485 fieldbuses for HVAC dampers, sensors, actuators, and small HMIs. The topology discovery capability in the new MCUs offers a drop‑in wiring model (single pair, multi‑drop) that installers understand, and a path to IP‑addressable endpoints without moving to bulky 10/100 Ethernet hardware.

Mortimer said the company is actively sampling and in design discussions with large OEMs and smaller subsystem vendors in this segment.

Robotics and physical AI

The robotics and physical AI themes were a larger part of the discussions at NXP Tech Days last week, in which the speakers extended the story that NXP’s CEO, Rafael Sotomayor, talked at Computex in Taiwan earlier this year, about deploying “right-sized intelligence” for scalable physical AI.

In this video conversation, Saloni Gankar, principal analyst for industrial semiconductors at analyst firm Omdia, offers her perspectives on some of the key discussions and announcement at NXP Tech Days, and discusses broader trends in the industrial and physical AI market for semiconductors.

An integral part of those systems are the distributed microcontrollers controlling everything like the motors, joints, grippers, and tactile sensors. While currently those MCUs are often connected by short‑reach buses that don’t offer good global visibility, Mortimer said its new microcontroller can become a standard building block for those distributed controllers, in that each limb or section of a robot—arms, hands, fingers—can be wired with 10Base‑T1S single‑pair Ethernet. As a result, every actuator and sensor node would gain an IP address and secure identity. This way, the top‑level AI controller can see and manage the entire topology, rather than treating downstream MCUs as opaque islands.

He indicated that at least one robotics customer is already actively designing with related technology and looking seriously at 10BASE‑T1S for end‑node connectivity.

The MCX A5 family is built on an Arm Cortex-M33 core, running up to 240 MHz. It offers up to 2 MB Flash, 640 KB RAM, and connectivity interfaces including UART, I²C, I3C, SPI, CAN FD, High-Speed USB, and FlexIO. Along with support from NXP’s FRDM development boards, the MCX A5 family is supported by the MCUXpresso developer ecosystem, including Rust support, comprehensive SDKs, Visual Studio Code integration, and LTS software releases. The MCX A5 family is sampling now.
