1 Introduction
The PCAN-MicroMod FD is a small plug-in board with CAN and CAN FD connection on
the one side and various physical inputs and outputs on the other side. The logical
linking of both sides is done by the microcontroller NXP LPC54618. With the MicroMod
FD, electronics developers can easily integrate I/O functionality with CAN connection
into their project.
The PCAN-MicroMod FD is configured using the supplied Windows software. In addi-
tion to simple I/O mapping to CAN IDs, function blocks are also available for
processing the data. The configuration created on the computer is transferred via
the CAN bus to the MicroMod FD which then runs as an independent CAN node.
Multiple modules can be configured independently on a CAN bus.
For the PCAN-MicroMod FD, ready-to-use motherboards in an aluminum housing and
an Evaluation Board for the development of own applications are available.
This document describes the hardware and the functions of the plug-in board PCAN-
MicroMod FD. Separate documents exist for the motherboards from PEAK-System
(e.g. Analog1) and for the Evaluation Board.

2 Electrical Connection
This chapter covers the signal assignment of the pins on the PCAN-MicroMod FD and
its possible circuitry.
2.1 Connectors
The PCAN-MicroMod FD has two double pin rows (A, B) with 50 pins each (first column
in the following tables). Thus, the MicroMod FD can be plugged onto boards with
matching socket strips (50-mil/1.27-mm grid, see also Appendix B Dimension Draw-
ings on page24).
Possible socket strip (2pieces) as counterpart to the PCAN-MicroMod FD: Amtek
5PS3MSA44-225GONPNRU-00
On request, PEAK-System offers an adapter for circuit boards with 100-mil/2.54-mm
grid). See also Appendix C CPU Adapter for 2.54mm Pitch on page25.
The MicroMod FD has a white mark on the upper left corner (pin A1) for better orient-
ation when plugged in.
Attention! Electrostatic discharge (ESD) can damage or
destroy components on the circuit board. Take precautions to
avoid ESD when handling the circuit board.

3.2 Reserved CAN ID 7E7h
To configure the PCAN-MicroMod FD, the 11-bit CAN ID 7E7h is used. Accordingly, the
PCAN-MicroMod FD Configuration program exchanges data with the module via the
CAN bus. When designing your CAN network, make sure not to use the CAN ID 7E7h in
any way.
3.3 Overview of Services
The PCAN-MicroMod FD provides various functions, called services. The availability of
services depends on the used motherboard.
Service Remark
Symbols
(CAN messages)
Definition of the CAN messages used by the PCAN-MicroMod FD with
Symbol names (CAN ID) and Variables resulting from Signals within the
data bits. Signals can contain initial values and timeout periods (e.g. for
CAN problems).
Digital Inputs
Assigned CAN messages can also be transmitted event-controlled. For
this purpose, the type of signal change (positive edge, negative edge or
both edges) is set as trigger.
Digital Outputs A Signal has influence either on the state of a digital output or on the
duty cycle at a preset frequency.
Analog Inputs An A/D value can be adjusted with scale and offset. Furthermore, a soft-
ware low-pass can be activated.
Analog Outputs
This service is only available with a D/A converter being applied to the
PCAN-MicroMod FD (e.g. using the Analog1 motherboard). A D/A value
can be adjusted with scale and offset.
Frequency Outputs Frequency and duty cycle are controlled independently with one Signal
each.
Digital Functions
The digital inputs can be logically combined with each other. The result
can be passed on to a Signal, to a digital output, or internally as feed-
back to an input.
Statistics Statistical data generated by the PCAN-MicroMod FD about the
processing and the environment can be passed to Signals.

Service Remark
Curve Definitions/Curves
(characteristic curves) Analog input data can be converted with the help of curves.
Rotary Encoders The service can process the signals of manual encoders connected to
digital inputs (standard quadrature with 2 bits, max. 500 pulses/sec.).
Functions
A collection of functions that convert one Signal value and place the
result on another Signal. Excerpt from the collection: Mult, Mod, And,
Hysteresis, Limit, RS Flip Flop, Switch Delay, Greater Than.

4 Configuration Program
With the enclosed configuration program PCAN-MicroMod FD Configuration for
Windows you can create, edit, and then transfer configurations to one or more PCAN-
MicroMod FD via CAN.
4.1 Prerequisites for the Configuration Transfer
Windows 10, 8.1 (32/64-bit)
PC-CAN interface from PEAK-System, e.g. PCAN-USB FD
CAN bus connection between the PCAN-MicroMod FD and the CAN interface of the
PC
On a computer without PCAN environment, you can create and edit a configuration
with the program and transfer the configuration later to the MicroMod FD using
another computer with PC CAN interface.
4.2 Installing the Configuration Program
The installation program for PCAN-MicroMod FD Configuration is located on the
supplied Product DVD.
Steps of the software installation:
1. Insert the Product DVD into the computer drive and execute the navigation
program either on request or manually (Intro.exe).
2. Klick on English >Tools.

Tip: In order to update the firmware, we recommend the use
of the Evaluation Board for the PCAN-MicroMod FD (IPEH-
003081 or kit IPEH-003082). This simplifies the connection of
the cabling on the one hand and the setting of the flash mode
on the other hand.
