Evaluates: MAX32000 MAX32000 Evaluation Kit General Description Quick Start The MAX32000 evaluation kit (EV kit) is a fully assembled Required Equipment and tested printed circuit board (PCB) that simplifies This section lists the recommended test equipment to evaluation and demonstrates the functionality of the verify operation of the MAX32000. It is intended as a MAX32000, a quad-channel pin electronics driver with guide only and some substitutions are possible. calibration comparator and level-setting DACs. Standard MAX32000 EV kit 50 SMA connectors are included on the EV kit for the inputs and outputs to allow for quick and easy evaluation Windows PC (Windows 10) with one to two USB 2.0 on the test bench. ports available The MAX32000 EV kit contains a microcontroller that Triple-output DC power supply translates between the SPI interface and USB to allow +9.25V/500mA the user to configure internal registers and modes -5.25V/500mA with graphical user interface (GUI) software running on +3.3V/100mA a PC. The EV kit includes Windows 10-compatible software that provides a simple GUI for configuration of all Function/pulse generator (recommend differential output high speed up to 1.5GHz) the MAX32000 registers through SPI. The EV kit is fully assembled and tested at the factory. High-speed oscilloscope (recommend 5GHz bandwidth) This document provides a list of equipment required to Digital multimeter evaluate the device, straightforward test procedure to SMA/SMA cable as needed for connection to the verify functionality, description of the EV kit circuit, com- oscilloscope ponent list, circuit schematic, and artwork for each layer of the PCB. Software and Drivers The MAX32000 EV kit is used in conjunction with Features the Arm Cortex -M4F microcontroller MAX32625PICO Low Power at High Speed Maximizes Driver application platform, or PICO board, to provide power Performance and control the device through a software application or 700mW per Channel GUI. Users also have the option to connect using SPI 2.57Gbps at +1V Programmed through their system with the J1 header on the EV kit. 280ps Typical Rise/Fall Times at +2V (20% to 80%) Install the MAX32000 EV Kit GUI Software Very Low Timing Dispersion at 50ps (typ) Wide Voltage Range from -2V to +6V The installation process should take less than 10 minutes Integrated VHH Programming Mode (4th-Level after downloading the software package.
