The AD-PQMON-SL provides a complete software and hardware platform for prototyping and evaluating high performance class S polyphase energy quality monitors. The design incorporates the ADE9430 high performance, polyphase energy monitoring IC that has an advanced metrology feature set (total and fundamental active power, volt amperes reactive (VAR), volt amperes (VA), watthour, VAR hour, VA hour, total and fundamental IRMS and VRMS, power factor) and the MAX32650 ultralow power ARM cortex-M4 with FPU-based microcontroller with 3 MB flash and 1 MB SRAM. The ADE9430 enables accurate energy monitoring over a wide dynamic range through its superior analog performance and digital signal processing (DSP) core. The ADE9430 simplifies the implementation and certification of energy and power quality monitoring systems by providing tight integration of acquisition and calculation engines. This solution can be used on a 3-phase system or up to three single-phase systems.

The design also features the MAX32650, which is a part of a new breed of low-power microcontrollers built to thrive in the rapidly evolving Internet of Things (IoT) named DARWIN. These MCUs are smart, with the biggest memories in their class and a massively scalable memory architecture. The MCU exposes all the necessary debug and programming features to enable a complete software development experience with the system. It is coupled with 512 Mb RAM and 64 Mb flash external memories to provide flexibility. The system's firmware is based on ADI's open-source no-OS framework and ADI proprietary ADSW-PQ-CLS library.

The solution has an on-board ADuM6424A Quad-Channel Isolator with Integrated DC-to-DC Converter. This DC-DC converter is used to supply all the components on the high voltage side. The ADUM6424A and the ADUM4152, which is a 5 kV, 7-Channel, SPIsolator™ Digital Isolator for SPI (with 1/2 Aux channel directionality), are used to isolate the connection between the ADE9430 and MAX32650.

The board can be supplied from the AC input through an isolated AC/DC converter or from the USB through the LTC3306, a 1.75 A Synchronous Step-Down Regulator. A logic based on several MAX40203, an Ultra-Tiny nanoPower, 1 A Ideal Diodes with Ultra-Low-Voltage Drop, selects based on availability the supply input with priority to the AC input.

The other 1.1 V and 1.8 V voltage rails needed by the MCU are converted from the 3.3 V input by the ADP225, a Dual, 300 mA Adjustable Output, Quick Output Discharge, Low Noise, High PSRR Voltage Regulator.

For high accuracy time keeping, the MAX31343 ±5 ppm, I2C Real-Time Clock with Integrated MEMS Oscillator is used.

The add-on board includes a standalone interface (a 64 x 4 display, 2 LEDs, and 5 buttons), an SD card for long time data logging, several industrial connectivity ports, and exposes an I/O prototyping area for I2C, SPI, GPIO, UART, 3V3, GND. The prototyping area can be also used for GPS / GNSS (e.g., Accurate Synchrophasor Measurement) or for external control signals.

For industrial connectivity, these are the following possibilities:

• T1L through the ADIN1110, an ultralow power, single port, 10BASE-T1L transceiver design for industrial Ethernet applications
• RS-485 implemented using the ADM2587E, a 2.5 kV Signal and Power Isolated, ±15 kV ESD Protected, Full/Half Duplex RS-485 Transceiver (500 kbps)

The ADMV96S-WGBE-EK1 is a complete evaluation and prototyping system for 60 GHz wireless data links. It consists of a pair of receiver and transmitter boards with a 1Gbp Ethernet interface on each side of the wireless link.

The 60 GHz wireless link is implemented by the ADMV9615 and ADMV9525 modules. These are coupled with a SerDes device which translates the modules’ SGMII interface to RGMII so that it can be connected to an ADIN1300 industrial low latency and low power 1 Gbps Ethernet PHY. This enables each side of the wireless link to act as an Ethernet port and essentially create a seamless wire-like connection between two ends of an Ethernet cable.

The on-board MAX32650 ultralow power ARM^® Cortex^®-M4 microcontroller controls the system’s operation and implements the algorithms to configure the wireless link in real time so that optimal link quality is constantly maintained over temperature and various operating conditions. An open-source software stack is provided for firmware development as well as reference applications. The MAX32650 can be programmed through a programming port which can also be used for firmware debugging.

The two sides of the wireless link are mounted on an adjustable rail so that the system can be configured and tested for various distances between the links. Each side of the link is powered from an external 12 V power supply.

An open-source GUI is provided for system configuration, monitoring, and control from a host PC.

• Industry standard form factor compatible with DIN rail mounts

The AD-SWIOT1L-SL provides a complete software and hardware platform for prototyping intelligent, secure, network capable field devices.

The design incorporates the AD74413R Quad-Channel, Software Configurable Input and Output and the MAX14906 Quad-Channel Industrial Digital Output/Digital Input ICs, allowing the multiplexing of several analog and digital functions on four channels which can be independently configurable through software to act as:

• voltage output / input
• current output / input
• digital input / output
• RTD measurement

A 10 Mbps single-pair Ethernet link, using the ADIN1110 10BASE-T1L MAC/PHY, enables remote data acquisition and device configuration. The 10BASE-T1L interface can also be used for powering the system via the Single-pair Power over Ethernet (SPoE) technology using the LTC9111 Powered Device (PD) controller. This way, power and data for the system is provided 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 24 V supply and up to 1.2 A 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 on-board MAX32650 Ultralow 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 a 1 Gb (128 MB) external RAM and a 64 Mb (8 MB) external flash memory to meet the most demanding applications and provide the flexibility to implement any protocol stack. Security features are enabled by the MAXQ1065 security coprocessor.

The system is accompanied by an open-source software stack and associated collateral, enabling a complete experience from evaluation and prototyping all the way to production firmware and applications development. An external programmer such as the MAX32625PICO MAXDAP Programming Adapter, or any other similar programmer supporting the SWD interface, is required to enable firmware programming and debug. The system’s firmware is based on Analog Devices’ open-source no-OS framework which includes all the tools required for embedded code development and debugging as well as 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 enable easy system configuration and displaying the acquired data in different ways.
