Introduction

1.1About the Integrator/IM-AD1

The Integrator/IM-AD1 is an interface module that is designed to be used in conjunction with the Integrator/LM-XCV600E+ or LM-EP20K600E+ and future compatible logic modules. It provides several standard automotive and industrial interfaces, and can be used for:

•proof of concept and application development

•benchmarking

•PrimeCell development and testing

•SoC prototyping.

The interface module is designed to be mounted on top of the logic module and provides connectivity for peripherals in the logic module FPGA.

Figure 1-1 on page 1-3shows the layout of the IM-AD1 and identifies the connectors.

The IM-AD1 can be used to implement additional peripherals to aid software development, for example additional timers or a vector interrupt controller. The IM-AD1 product consists of:

•a fully populated PCB

•example bit files for an LM

•example driver source code

•this documentation.
