    产品详情

    AD-EthernetAPLDevice-SL is a complete Ethernet-APL field platform designed for prototyping intelligent, secure, and connected field devices.

    The platform is certified for intrinsic safety (Ex ia IIC Ga) and tested for Ethernet-APL compliance. It is also functional safety ready (SIL2), featuring the MAX42500 voltage monitor, with integrated windowing watchdog, the MAX6613 temperature sensor, the ADFS7124-4 sigma-delta ADC functional safety approved to SC3, and complete FMEDA documentation.

    The system integrates the MAX32690—a dual-core ARM Cortex-M4 with FPU and a RISC-V co-processor. This MCU is paired with external RAM (512 Mb) and Flash (64 Mb) to meet the demands of high-performance applications.

    A 10 Mbps single-pair Ethernet link, enabled by the ADIN1110 10BASE-T1L MAC/PHY, supports remote data acquisition and system configuration.

    The platform is APL-compliant and powered via Single-Pair Power over Ethernet (SPoE), supporting an input voltage range of 9 V to 15 V. It is recommended to use the DEMO-ADIN1100D2Z as both the power source and media converter for Ethernet signals (10BASE-T1L ↔ 10BASE-T).

    The kit includes a third, non-intrinsically safe board that provides access to the RISC-V JTAG interface for debugging.

    An open-source software stack and supporting collateral are included, enabling seamless experience from evaluation and prototyping to production firmware and application development. The stack includes drivers and example applications for a wide range of ADCs, DACs, sensors, and other industrial components, accelerating development.

    The platform supports Zephyr (with an available board definition) and is also supported in Code Fusion Studio.

    An example PROFINET stack software application is available to enable easy evaluation and system prototyping (myanalog.com registration required).
