2commModule MBP
The commModule MBP is a surface mountable fieldbus communication module with minimum footprint. It
is typically integrated into an intelligent field device mapping industrial intrinsic safe fieldbus Profibus PA
and FOUNDATION Fieldbus to the field device.
CAUTION
The commModule MBP is certified for hazardous areas if used in accordance with its
specification and operating conditions. See also Operating conditions for use in hazardous
environment .
2.1 Diagram
The block diagram below shows the design of the commModule MBP:
2.2 Intended use
This product has been designed to be integrated as a system component by qualified hardware engineers.
2.3 Ordering information
The commModule MBP is available as a potted version (#STD), not suitable for reflow soldering and a non-
potted version (#STD_NOP), suitable for reflow soldering.
The Ex approval of commModule MBP STD_NOP/HW is void without potting. See certificates for
details. Potting must be applied on final assembly. Requirements specified in Section 6.6 of EN IEC 60079-
11 must be met. Potting process and the compound have to be assessed by the notified body of the
manufacturer of the complete equipment. Both versions can be ordered in units of 90 (VPE90). For
evaluation purposes sample packs in units of 5 (VPE5) are available.

3.3 Pullups and pulldowns
Weak pullups are provided on all GPIO pins. Pullups for TDO and TDI are not included on the commModule
MBP and must be included on the application base board (pullup to Pin 7 of commModule MBP).

3.4 Flash programming and debugging interface
The following signals of the microcontroller are required for programming with the Renesas Flash
Programmer.
See the commModule MBP Evaluation Kit user guide for details. The usage of the debugging interface is
detailed in document "E1/E20 Emulator – additional document for User’s Manual (RX User System Design)
from Renesas".

CAUTION
Some memory blocks are reserved for the bootloader or the firmware. They must not be
modified as this will invalidate the software and you will no longer be able to boot the
commModule MBP. Only programming project files provided by Softing must be used to
reprogram the module. Do not select the programmer option "Erase Chip"
3.5 Fault Disconnect Equipment
External fault disconnect equipment (FDE) can be optionally added using the assigned FDE pins. If not in
use, connect signal FDE_PO to FDE_PI and signal FDE_NO to FDE_NI.
3.6 Simulate enable
Fieldbus conformance testing requires switching the application to simulation mode. Simulation mode is
enabled by signaling low on pin SIM_EN_P31.
For the registration of the final device by the FieldComm Group this signal must be accessible to the
fieldbus testing personnel.
