Product Details

The MAX22199 evaluation kit (EV kit) provides the hardware and software necessary to evaluate the MAX22199 Octal Industrial Digital Input device. The MAX22199 EV kit receives commands from a PC through the USB port to create a SPI interface for communication between the software and the MAX22199 on the EV kit. The MAX22199 EV kit also has a Pmod™ compatible connector for SPI communication with an external host device such as a MCU or FPGA.

The EV kit includes a graphical user interface (GUI) that provides communication between the target device and the PC. The MAX22199 EV kit has a MAX22199 device that supports Type 1, 3 inputs with the current sink limit set by an on-board resistor. The MAX22199 EV kit is designed to support transient immunity testing for ESD, EFT, and Surge according to IEC 61000-4-2, IEC 61000- 61000-4-4, and IEC 61000-4-5 respectively. The EV kit can operate in multiple modes, as shown in the System Block Diagram:

1) USB Mode: If SW1 are all closed, the MAX22199 SPI receives commands through the USB port from the Maxim-supplied EV kit software.

2) Pmod Mode: If SW1 are all open, the MAX22199 SPI receives commands through the PMOD1 connector. This industry standard connector connects to popular MCU or FPGA platforms. The user is required to generate firmware to provide the SPI commands.

Applications

  • Building Automation
  • Distributed Control System
  • Motor Control
  • Programmable Logic Controllers
