The ADI AD-SWIOT1L-SL Platform features a 10Mbps single-pair Ethernet link, using the ADIN1110 10BASE-T1L MAC/PHY, that allows remote data acquisition and device configuration. The 10BASE-T1L interface can also power the system through the Single-pair Power over Ethernet (SPoE) technology employing the LTC9111 Powered Device (PD) controller. This way, power and data for the system are supplied over the same cable to significantly simplify the cabling infrastructure and cost.

For applications requiring high current capabilities, the system can be powered from an external 24V supply, and up to 1.2A can be output on any of the channels configured as digital outputs. The power supply solution also includes the ADP1032 high-performance, isolated micropower management unit (PMU) to provide power and digital control for software configurable I/O devices in one of the most compact formats. The LT8304 micropower no-opto isolated flyback converter completes the power tree to provide isolated power to the digital part of the design.

The onboard MAX32650 ultra-low power ARM® Cortex®-M4 microcontroller exposes all the necessary debug and programming features to enable a complete software development experience with the system. It is coupled with 1Gb (128MB) external RAM and 64Mb (8MB) external flash memory to meet the most demanding applications and provide the flexibility to implement any protocol stack. The MAXQ1065 security coprocessor enables security features.

The system is accompanied by an open-source software stack and associated collateral, enabling a complete experience from evaluation and prototyping to production firmware and application development. An external programmer must help with firmware programming and debugging, such as the MAX32625PICO MAXDAP programming adapter or any similar programmer supporting the SWD interface. The system’s firmware is based on Analog Devices’ open-source no-OS framework, which includes all the tools needed for embedded code development and debugging and libraries enabling host-side connectivity for system configuration and data transfer over the UART or the 10BASE-T1L interfaces. A PC application with a user-friendly graphical interface is provided to allow for easy system configuration and to display the acquired data differently.
