The MPU is a 68000 microprocessor with 32-bit data, address and stack registers. It has a 16 MByte direct addressing range, 16-bit data path and runs at 16 MHz.
The local memory consists of two 32-pin JEDEC sockets for 1-, 2- or 4-MBit type EPROMs and two 32-pin JEDEC sockets for 1- or 4-MBit type SRAMs. This configuration gives a maximum EPROM and SRAM space of 1 MByte each.
The 68681 DUART (Dual Asynchronous Universal Receiver Transmitter) has programmable operating modes and data formats for each channel. It can operate at baudrates from 50 to 38.4k Baud. Channel A has an RS-232 interface on a front panel connector. The channel B signals are available at TTL levels via the VMEbus P2 connector.
The 82C200 from Philips is a highly integrated stand-alone protocol controller for the Controller Area Network (CAN). It contains all the necessary features required to implement a high performance communication protocol. The programmable transfer rate of the 82C200 goes up-to 1 MBaud.
The 82C251 is the interface between the CAN protocol controller and the physical bus. It is intended for high speed applications up-to 1 MBaud and is fully compatible with the ISO/DIS 11898 standard.
