1.1 About 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 1-3 shows 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.

1.2 Interface module features and architecture
This section describes the main features of the interface module and its architecture.
1.2.1 Features
The main features of the interface module are as follows:
• two Bosch CC770 Controller Area Network (CAN) controllers
• two 8-channel 12-bit Analog to Digital Converters (ADC) with 200ksamples/s
sampling rate and 0-5V buffered inputs
• two 12-bit Digital to Analog Converter (DAC) channels with 0-5V outputs
• two L298 stepper motor drivers configured for bipolar motors
• two stepper motor control outputs for use with off-board drivers
• two 3A MOSFETs configured as switches for the Pulse Width Modulated (PWM)
outputs
• RS232 serial transceiver
• two 32-bit General Purpose Input Output (GPIO) connectors
• JTAG (Multi-ICE) pass-through connector
• logic analyzer connector connected to the GPIO bus.

1.3 Links and LEDs
The interface module provides one link and one LED. These are the CONFIG link and
CONFIG LED.
Fitting the CONFIG link places all of the modules in the stack on which the interface
module is mounted into CONFIG mode. This mode enables you to reprogram the FPGA
image in the configuration flash on the logic module(s) using Multi-ICE (see the user
guide for the logic module).
The CONFIG LED lights to indicate when the stack is in CONFIG mode.

1.4 Care of modules
This section contains advice about how to prevent damage to your Integrator modules.
Caution
To prevent damage to your Integrator system, observe the following precautions:
• When removing a core or logic module from a motherboard, or when separating
modules, take care not to damage the connectors. Do not apply a twisting force to
the ends of the connectors. Loosen each connector first before pulling on both
ends of the module at the same time.
• Use the system in a clean environment and avoid debris fouling the connectors on
the underside of the PCB. Blocked holes can cause damage to connectors on the
motherboard or module below. Visually inspect the module to ensure that
connector holes are clear before mounting it onto another board.
• Observe ElectroStatic Discharge (ESD) precautions when handling any
Integrator board.
Integrator/IM Interface Modules are designed to connect with ARM and third party
development platforms that meet the interface specification. Interface Modules connect
to the top of a stack because there are no EXPA/B connectors on the top side.
