Introduction6
• "Technical Data" on page 40
contains the technical data of the ES1651.1 Carrier Board.
1.1 Applications and Features
The ES1651.1 Carrier Board acts as a carrier board for up to four I/O modules
in VMEbus systems. All modules of types ”PB4350XXX” and ”PB1651XXX”
can be used in any combination. An SPI control unit realized in the FPGA of the
board converts the parallel data flow of the processor into a serial bit flow for
the SPI interfaces of the I/O modules.
The ES1651.1 Carrier Board has a crankshaft angle clock bus for testing engine
ECUs in LABCAR projects; this can be used to synchronize I/O modules with a
central crankshaft angle clock for speed-synchronous signal acquisition and
signal generation. The crankshaft angle clock bus is routed to the 9-pin Sub-D
connector on the front panel of the board so that the crankshaft angle clock
can be both supplied externally as well as routed to the outside.
Synchronization Bus
The ES1651.1 has a synchronization bus to synchronize the I/O modules of an
ES1651.1 Carrier Board with each other. It consists of four lines which can be
configured independently of each other. The bus is also routed to the 9-pin
Sub-D connector on the front panel of the board so that the signals can be
Note
Some components of the ES1651.1 Carrier Board may be damaged or
destroyed by electrostatic discharges. Please keep the board in its storage
package until it is installed.
The ES1651.1 Carrier Board should only be taken from its package, config-
ured and installed at a working place that is protected against static dis-
charge.
Note
The components, connectors and conductors of the ES1651.1 Carrier Board
may carry dangerous voltages.
These voltages may even exist when the board is not installed in the VMEbus
system or the VMEbus system is powered off.
Make sure that the board is protected against contact during operation.
Disconnect all connections to the ES1651.1 Carrier Board before removing
the board from the VMEbus system.

Introduction 7
supplied externally or routed to the outside to synchronize I/O modules on
other carrier boards. The synchronization lines can also be stimulated from
within the simulation model.
CAN Interfaces
There are two identical CAN channels on the ES1651.1 Carrier Board for con-
necting the board to the CAN bus. The transceiver functionality is realized on
piggybacks so that, if necessary, different transceivers can be used than those
intended, i.e. than the PCA82C251 transceiver by Philips for high-speed CAN
applications 1and the MAX3055 transceiver by Maxim for low-speed CAN
applications2.
The ETAS PB1651CAN1 transceiver module is a combined high-speed/low-
speed CAN transceiver module3with galvanic isolation of the CAN channels.
Relays are used to toggle between high-speed and low-speed functionality.
The CAN controller functionality is realized in the MPC555 processor of the
board which has two CAN channels on board.
VMEbus Interface
The ES1651.1 Carrier Board has a VMEbus slave interface and reacts to ”A24
non privileged data access” accesses (VMEbus address modifier 39 hex).
The position of the 64-kByte VMEbus address space of the board can be set
either dynamically or statically. Data is exchanged with VMEbus master boards
via a 32-kByte DPRAM. The board can trigger interrupts at the VMEbus.
Inspection and Versioning Data
Inspection and versioning data of the board are stored in a serial non-volatile
data memory. PB1651CAN1 transceiver modules also have serial data memo-
ries for version and inspection data.
Processor
In addition to the CAN channels listed, the MPC555 processor of the board
also has a 448-kByte ROM memory which is large enough for program code
and data; this is why the optional external ROM memory is not assembled.
1. High-speed CAN systems (data rates between 125 kBaud and 1 MBaud) are
used e.g. for engine and transmission controls, ESP, ASR, ACC and ABS.
2. Low-speed CAN systems (data rates up to 125 kBaud) are used in the field
of convenience electronics.
3. The terms fault-tolerant CAN and low-speed CAN are synonymous.
