The PAC024 is a fully featured single board
computer using Motorola's MC68376 32-bit microcontroller.
The board has a rich set of hardware features, including 4 channels of bipolar
stepper motor control, to enable it to control a variety of applications.
It can be used either as a standalone controller or used via the CANbus
or RS485 multidrop serial interface to provide slave capablities to a variety
of controllers. On-board addressing allows up to 64 boards to be used on
the same bus.
Powerful Motorola 32-bit MC68376 microcontroller, using
the CPU32 instruction set.
Programmable up to 20 MHz.
512 Kbytes Flash memory 16 bits wide for program storage.
128 Kbyte x 8 battery backed SRAM.
32 Kbyte x 8 serial EEPROM for long term data storage.
4 channels bipolar stepper motor interface. Individually link selectable
in full-, half-, quarter- and
eighth-steps.
8 digital inputs, individual link selectable to switch PNP or NPN.
8 digital outputs. All outputs PNP, Drive capability 4 amps per 4 channels.
1 channel 0-10 volt analogue output.
1 Serial communication channel, selectable for RS232 or RS485 full duplex.
1 channel CANbus interface at 1 Mbits/second. Full implementation protocol
CAN 2.0 A and B.
10 way Motorola recommended BDM header for development support in 68000
assembler or 'C'
languages. Addition of PAC018 debug board allows full program debugging,
hardware breakpoints etc. via PC.
On board support for programming on-board Flash memory via PC COM port.
Board rotary switch addressable 0 – 63 for use in CANbus or RS485
multidrop mode.
All interfaces fully opto-isolated.
Single 24 volt supply. Reverse voltage protected.
All connectors simple screw terminal blocks, 3.81 mm pitch.
Board size 230 x 115 mm.
